Map of Saipan Showing the Invasion Forces

I like to think that I am an expert on WWII psychological operations in the Pacific. I wrote 30,000 words on the U.S. Army Psychological Warfare Branch operations in the Philippines, and another 53,000 words on the U.S. Navy and Office of War Information leaflets prepared on Saipan. Then I ran across the name of U.S. Marine Corps Lieutenant Bob Sheeks, a name I had never heard of. As I studied his actions during the initial American assault on Japanese-occupied Saipan in WWII, I discovered that he had done things that were not officially credited to U.S. forces until much later. He decided that trying to talk the Japanese into surrendering was important and began writing leaflets and loudspeaker messages. Up until that time it was believed that no Japanese would ever surrender and for the Marines it was a lot easier to just shoot them, burn them or blow them up. Sheeks also thought that the Japanese needed to be taught how to surrender because the concept was unknown in Japan. He obtained a loudspeaker, and talked a Marine motor sergeant into placing it on a jeep. He also bought portable loudspeakers and took it upon himself to try and talk the Japanese military and civilians out of caves. It was an amazing story and totally unknown to me. So, this short story will mention some of the ground-breaking PSYOP actions that Bob Sheeks did.

Marines Hit the Beach during the Invasion of Saipan

Let me start with a very brief introduction to the battle for Saipan. The Battle was fought from 15 June to 9 July 1944. The Allied invasion fleet embarking the expeditionary forces left Pearl Harbor on 5 June 1944. The U.S. 2nd Marine Division, 4th Marine Division, and the Army's 27th Infantry Division, commanded by Lieutenant General Holland Smith, fought the 43rd Infantry Division of the Imperial Japanese Army, commanded by Lieutenant General Yoshitsugu Saito.

The invasion surprised the Japanese high command, which had been expecting an attack in the Pacific further south. Admiral Soemu Toyoda, Commander-in-Chief of the Japanese Navy, saw an opportunity to attack the U.S. Navy forces around Saipan. On 15 June, he gave the order to attack. But the resulting battle of the Philippine Sea was a disaster for the Imperial Japanese Navy, which lost three aircraft carriers and hundreds of planes. The garrisons of the Marianas would have no hope of resupply or reinforcement. Without resupply, the battle on Saipan was hopeless for the defenders, but the Japanese were determined to fight to the last man. The Japanese used the many caves in the volcanic landscape to delay the attackers, by hiding during the day and making sorties at night. The Americans gradually developed tactics for clearing the caves by using flamethrower teams supported by artillery and machine guns.

The Banzai Charge

The Banzai Charge is a human wave attack mounted by infantry units. This term came from the Japanese cry Tennoheika Banzai i.e. “Long live the Emperor.” It was a suicidal attack, where Japanese troops gave up their lives willingly to kill as many enemies as possible before their own death. Those that were unable to make the charge would kill themselves by holding a grenade against their chest. Surrender was unthinkable and the worst form of cowardice to the Japanese soldier.

By 7 July on Saipan, the Japanese had nowhere to retreat. Saito made plans for a final suicidal banzai charge. On the fate of the remaining civilians on the island, Saito said, “There is no longer any distinction between civilians and troops. It would be better for them to join in the attack with bamboo spears than be captured.” At dawn, the remaining able-bodied troops, about 3,000 men, charged forward in the final attack. Amazingly, behind them came the wounded, with bandaged heads, crutches, and barely armed. The Japanese surged over the American front lines, engaging both army and Marine units. Of course, sharp sticks cannot defeat weapons so the Japanese were beaten back with terrible losses.

JapCivilianSuicides.JPG (215380 bytes)

Believing the horrific tales of American atrocities fabricated by Japanese military propagandists, Japanese civilians commit suicide by flinging themselves and their children from the cliffs at Marpi Point on the island of Saipan. Unable to intervene, U.S. Marines watch helplessly as the civilians end their lives by drowning or falling on the rocks below.

Author Mark Riggs says in Flamethrower:

Saipan was the first Pacific battlefield where the Americans also encountered a large enemy civilian population, possibly as high as 27,000. This was problematic because the Japanese population was mixed in with Japanese troops and about 3,350 Chamorros and Carolinians making the bombardment of targets somewhat restricted. A pamphlet given to the 2nd Marne Division cautioned:

“We…sure that a civilian is fighting us or harming our installations before we shoot him. International law…demands that civilians who do not fight back ...must, whenever possible be taken alive and must not be injured or have their possessions taken from them except after a due trial by competent authority.”

By the end of the first week of July, the Marines had defeated most of the Japanese forces on Saipan and had pushed the remaining units and most of the Japanese civilians to the north of the island around Mount Marpi. The enemy was now crowded around hundred-foot precipices that plummeted from a plateau surrounding Mount Marpi overlooking the ocean. This mountain was bolstered on almost all sides by imposing cliffs dotted with caves and the damage caused by shell blasts from U.S. warships. Civilians moved north with retreating troops stopping at the shore with no place to escape, and, just like their soldiers, the civilians started killing themselves instead of allowing themselves to be taken prisoner by the Americans. Many Marines did all they could to help civilians. As soon as the Marines ascertained those suicides were occurring at Marpi Point, they had interpreters on megaphones and loudspeakers tell them they would not hurt them. Scout planes dropped fliers notifying civilians of U.S. servicemen’s good intentions.

Lieutenant General Yoshitsugu Saito, the Japanese garrison’s commander, had ordered civilians to commit suicide in the event of defeat. For years, Japan had fed its citizens the propaganda describing Americans wanting to cut the “testicles” off of Japanese and as “sadistic, redheaded, hairy monsters who committed unspeakable atrocities before putting all Nipponese, including women and infants, to the sword.” One document claimed Americans were “barbarous and execute all prisoners” and kill some “by cutting them up and crushing them with steam rollers.” Believing the propaganda, many civilians trapped at Marpi Point decided to kill themselves. Mothers threw their infants off cliffs and then jumped. A group of a hundred passed grenades out to everyone from young children to elderly adults; then they held the grenades next to their stomachs, pushed the pins and blew themselves up. Women, men, boys, and girls slit each other’s wrists and bled out. Others took cyanide.

Japanese soldiers hid with women and children. When some infants started crying and threatened to reveal their hideout, a sergeant said, “Kill them yourself or I’ll order my men to do it.” With that order, “several mothers killed their own children.”

Government-controlled news reports in Japan glorified this suicidal fanaticism. One newspaper extolled the mothers who killed their children and themselves as the flowers of womanhood. This was obviously crude propaganda, but to its purpose was chilling to convince civilians that they too were expected to fight to the bitter end to protect the homeland. The army had imposed its standard of no surrender onto the civilian population to legitimize the notion of death before dishonor and collective suicide for all Japanese.

We also find this Japanese “Hate Propaganda” mentioned in The Conquering Tide:

The root was in hate propaganda. It described Americans as non-humans, “they were something like demons or beasts.” They were the “hairy ones” or the Anglo-American demons. They would have raped women and girls. They would have crushed civilians captured under tracks of the tanks. The Marines were especially dreaded.

According to a story that circulated widely among the Japanese in Saipan, all Marine recruits were forced to kill their parents before being inducted into service. It was said that captured Japanese soldiers would be tortured excruciatingly, noses, limbs and ears would be cut off, blinded and castrated, cooked and fed to dogs. Japanese newspapers reproduced photos of Japanese skulls mounted on American tanks.

A cartoon in a magazine by an American soldier, which was later reproduced and translated in the Japanese press, had suggested that the Marines had received a “Japanese hunting license” with the promise of “open season” on the enemy, with free ammunition and equipment and with pay. Other cartoons, reproduced in Japan, characterized the Japanese as monkeys, rats, beetles or lice.

It seems clear that many of the comments and cartoons made by patriotic Americans attacking the Japanese were used by the enemy to convince their troops that the Americans were monsters.

A Leaflet to General Saito to save Civilian Lives

Although we do not know exactly who prepared and dropped this leaflet, it is addressed to Lieutenant General Saito and was dropped on Saipan at 1630 on 7 July 1944. The text is:

Lieutenant General Saito,

This is the last chance to save the lives of non-combatants on Saipan Island.

If the Japanese troops want to sacrifice their lives uselessly, that is their affair; but the American forces do not want to kill non-combatants. If the Japanese military authorities are human beings they will allow the innocent civilians to come over to the American lines and save their lives. This is the last chance.

This is what to do: all non-combatants, whether Japanese, Koreans or Natives will come down the Banadero Road on the northeast side of Saipan towards Tanapag at 0900, Friday 7 July. They will come unarmed and carrying white flags held high. If they do this, the American forces will receive them and save their lives. Americans do not want to kill non-combatants. 7,000 civilians of Saipan are already safe in American hands. As human beings, let us save the lives of the innocents.

Civilians can come to the American lines individually before the specified time but Friday, 7 July at 0900 in the morning is the last chance.

Tell everyone the time and place, Banadero Road at 0900 Friday morning.

The Commander of All American Forces on Saipan Island.

At the end of June, Hirohito sent out an imperial order encouraging the civilians of Saipan to commit suicide. The order authorized the commander of Saipan to promise civilians who died there an equal spiritual status in the afterlife with those of soldiers perishing in combat. More than a 1,000 Japanese civilians committed suicide in the last days of the battle to take the offered privileged place in the afterlife, some jumping from places later named "Suicide Cliff" and "Banzai Cliff". Today the sites are a memorial and Japanese people visit to console the victims' souls.

In Japan the suicides were considered to be the highest form of patriotism. Jeff Kingston wrote in the JAPAN TIMES:

The suicides in Saipan drew considerable attention and praise in Japan. A correspondent from the Yomiuri praised the women who committed suicide with their children by jumping from the cliff, writing that they were, “the pride of Japanese women.” He even went so far as to call it, “The finest act of the Showa period.” Similarly, Tokyo University professor Hiraizumi Kiyoshi gushed in the Asahi Shimbun, “100 or 1,000 instants of bravery emit brilliant flashes of light, an act without equal in history.”

The Japanese commander, Gen. Yoshitsugu Saito, reportedly said: “There is no longer any distinction between civilians and troops. It would be better for them to join in the attack with bamboo spears than be captured.”

The loss of Saipan, with the death of at least 29,000 troops and heavy civilian casualties, precipitated the resignation of Japanese Prime Minister Hideki Tojo and left the Japanese mainland within the range of Allied B-29 bombers.

Lieutenant Robert B. Sheeks on Saipan 1945

There is a website dedicated to Major Robert B. Sheeks; and a book The Conquering Tide: War in the Pacific Islands, 1942-1944 that mentions Lieutenant Sheeks early PSYOP activities; and a book titled One Marine’s War by Gerald A. Meehl, published by the Naval Institute Press, Annapolis, Maryland, in 2012. These were a great help in learning of Sheeks background. Bob Sheeks and his son Robert were also very helpful, opening up their files to me and allowing me to use whatever I desired in this article. They were extremely generous.

In most cases, young men are born liberal and as they grow older become more conservative and learn to hate their enemies. In the case of Bob Sheeks it was just the opposite. Brought up in Shanghai before America entered the war and seeing the brutal way that Japanese troops treated the Chinese, Bob had an early hate for the Sons of Nippon. As he grew older and was taught Japanese by American Nisei instructors, and later interviewed and saw wounded and dying Japanese troops and civilians on Saipan he increaingly wanted to try to save their lives.

Born 8 April 1922 in China to American parents, Bob grew up spending his early boyhood in Shanghai.He attended the Shanghai American School until thirteen years of age. While in China, as a child, Bob met and admired members of the Fourth Marine Regiment that had been stationed in Shanghai since 1937. He decided at an early age that he would be a Marine someday.

Japan's attack on Shanghai took place in 1932. Bob witnessed some horrific scenes of brutal Japanese attacks on Chinese civilians. He mentioned them in a War in the Pacific Oral History Collection. Some of his comments were:

The Japanese did all kinds of things to terrify the Chinese and keep them from resisting. They would tie up a whole bunch of people and douse them with fuel and ignite them, or they would shoot a whole lot of people needlessly.

The Sheeks family returned to the U. S. in 1935, thus avoiding the large-scale Japanese invasion and occupation of China which followed in 1937.

In 1938, Robert Sheeks enlisted in the Marine Corps Reserve, at Spokane, Washington. Robert had submitted his application to Harvard. He was accepted on a scholarship and entered Harvard College in September 1940. After Pearl Harbor, Sheeks was recruited out of college by the U.S. Navy intelligence in Washington D.C., to be crash-trained in Japanese language and intelligence; then to be commissioned in the Marine Corps. It was thought he would learn Japanese rapidly, as he could speak Chinese, and had studied some written Chinese and Japanese.

JapLanguageSchoolBook.jpg (44272 bytes)

One of the U.S. Navy Language School’s Japanese Text Books

The Navy's Japanese language training lasted a year, first at U.C. Berkeley, then at The University of Colorado at Boulder. Curiously, the American government did not want the Nisei who were helping in the war effort to be near the ocean where they might signal Japanese submarines or spy for the enemy. The books that Bob used to study Japanese were the six-volume Naganuma Readers. The students were issued books and bound notebooks. They were told that for the period of instruction they would read and learn each book, memorize everything they learned, speak only Japanese, and take a test each week. Those that could not keep up would be returned to their units and end up fighting the war. The language books were to be kept in good condition and returned at the end of the course. Bob was the kind of officer that wanted to have his references nearby in case of emergency, so he “confiscated” several of the books and took them with him when assigned to the Pacific. One wonders what the library fees would be after seven decades. Curiously, when I spoke to an individual that had knowledge of the Marine interpreters he told me:

Actually, most of the language officers kept their books and dictionaries for their duties in the Pacific and in Washington, DC. Many of the interpreters still had those school books marked “Property of the US Navy,” and carrying stamps stating that they must be returned long after the war was over. I don’t believe the Navy or the Marine Corps ever wanted those books back. If they did, the turn in of books would have been part of their out-processing.

He was assigned to the Second Marine Division Intelligence Section in New Zealand; landed at Tarawa on D-Day in November 1943; likewise on the D-Days at Saipan and Tinian in June and July 1944. It was on Saipan that Sheeks innovative theory of how to conduct PSYOP to save both American and Japanese lives came to fruition. What I really want to stress at this time is that Sheeks did not go to any military Psychological Operations school and apparently was not trained to talk enemy troops out of fortified caves. He was an interpreter. His orders were to read captured paper looking for any strategic value and to interview captured prisoners to see if they had any information of tactical or strategic value. His PSYOP activities, which would have been called "propaganda" at the time, were mainly his own ideas.

When I mentioned my amazement at his accomplishments, Sheeks was quick to share the praise. He said:

Leaflets and the loudspeakers seemed essential to try to reduce enemy resistance. What had made the initial and strongest impact on me was my great frustration at being unable to communicate to resisting Japanese on Betio Island (Tarawa). At times they were in a bunker only several feet or yards away. Our action was bullets, explosives, flamethrowers, or live burial by bulldozer. I wanted us to be able to do better in subsequent land actions. The next one was the Marianas, Saipan/Tinian.

These leaflets and translation documents were produced at the Pearl Harbor Joint Intelligence Center Pacific Ocean Area (JICPOA) just prior to the Saipan invasion in early 1944. My immediate boss, Captain John C. Pelzel, USMCR, Assistant. D-2 (Intelligence), wrote the supporting translation documents to accompany the leaflets to Marine Corps headquarters (Saipan) as part of the file.

It was my job to bundle the leaflets into stacks bound by easily breakable string, attached to a strong cord, with its end fastened inside the cockpit of the aircraft. We used a single-engine Marine Corps artillery spotter plane for dissemination.

In fact, there was no person or source available to use as a guide. I received no relevant training.In fact, the term "psychological operations" was unfamiliar to me, and was not in use in the Marine Corps. Although a deadly serious effort, the Second Marine Division leaflet drop project that I headed came with no instructions or orders from top level command. I worked on the leaflets alone, but with approval and in consultation of my superiors, Captain Pelzer, and Colonel Thomas Colley.

After the leaflets were dropped, some Japanese military and civilians and some Koreans who surrendered carrying our leaflets.

Today, seven decades after WWII, the United States Marines have started their own PSYOP School and military occupational specialty 0521. We could say that Bob Sheeks is a foundation of that school.

PSYOP Activities

Sheeks had been in the Tarawa invasion and seen the death and destruction there. He thought there must be a better way to get prisoners and information. At that time they only got a prisoner when the man was badly wounded or knocked unconscious by artillery or aerial bombing. When the Marines returned to Hawaii he put his mind to figuring out how he could do his job better by involving other interpreters. This is mentioned by Meehl who wrote:

Near the top of the list was how to communicate surrender instructions to Japanese holed up in fortified positions. It was very difficult for anyone to hear anything over the noise of combat, least of all potential POWs in concrete bunkers. Amplified megaphones loudspeakers could be the answer…Bob proposed dropping leaflets printed with basic surrender information, and then using amplified sound systems to broadcast surrender appeals to civilians and to Japanese military in fortified positions.

Some of the loudspeaker and megaphone messages appeared in Field Directives 1 through 4. I will quote a few of them:

You are completely surrounded and the rest of the Island has been taken.

We do not wish to harm you. It is safe to come out now.

It is all right to carry children and help the wounded.

Foolish resistance will bring only useless death.

Be wise, come out immediately

Notice that this is one man without PSYOP training coming up with ideas like aerial propaganda leaflets, jeep-mounted loudspeakers and other advanced concepts. Since the Marines were busy training and had no time to play, he talked his commander into giving him some troop recreation funds to buy extra speakers and megaphones. Bob emphasized on his leaflets that surrender was an honorable act and explaining actually how to go about surrendering. He composed four different leaflets; three to be Japanese and one to be Korean.

SheetsPatrolCard01.jpg (171673 bytes)

SheetsPatrolCard02.jpg (226348 bytes)

The Patrol Card

Sheeks also prepared what he called a patrol card. In later wars like Vietnam, Afghanistan and Iraq this would be called a "pointee-talkie card," where an American could point to a phrase in a foreign language and make himself understood. Bob put a sentence on the card to remind the Marines how important it was to take prisoners:

Every prisoner turned in means the saving of American lives, time, and material.

The card was folded with four sides. On the front there is an English-language message and a series of phrases in Japanese and English that can be used as a pointee-talkee card. The back has one long message in Japanese and another in Korean. The Japanese language message is:

You and your comrades have fought well; no one can be expected to do more. Those who remain can die or kill themselves if they wish. However, before the lives of brave Japanese men are exchanged for a little cheap ammunition, let them think for a moment.

If you have been badly led or overwhelmed by sheer numbers, it is not your fault. You and your comrades have done your duty; you will be treated honorably as fellow military men. We do not wish to kill needlessly. Help us prevent further useless loss of Japanese lives. If there are people in the vicinity, of whom you know, accompany us to their place of hiding and tell them to come out in safely.

We will show you how we wish you to approach the position on a map, or by some other way. Watch us so we can make our actions clear to each other. When you are close enough to call to them, tell them the truth, that they will be given food, water, tobacco, and medical care. Tell them to come forth unarmed with hands up. When we motion you to return, come back in single file.

We will keep you “covered” by guns. Make no quick motions which may be suspicious. Stay in our line of vision.

The Korean-language text is:

This war is between Japan and the United States

Korea has been under Japanese occupation for 26 years. We realize that Koreans have not had their freedom and have been forced to work for the Japanese. You are not our enemies. Koreans who were at Tarawa in the Gilberts and at Kwajalein in the Marshalls are now happy and well in American camps. You too, will be given food, tobacco and medical care. If you wish to work you will be given a fair wage.

We want you to help us prevent useless loss of Korean and all civilian lives. We also want you to help us take Japanese prisoners. If you know of Koreans, civilians, or Japanese troops in this immediate vicinity, point out their position to us.

If you think you can induce them to surrender, we will show you how we wish you to approach them, by pointing on a map, or by some other way. Watch us so we can make our actions clear to each other. When you are close enough to call to them, tell them the truth, that they will be given food, drink, tobacco, and medical care. Tell them to come forth unarmed with hands up. When we motion you to return, lead them back in single file.

We will keep you “covered.” Make no quick motions which may be suspicious. Stay in our line of vision.

Although not on the card above, language officers were often given a list of words and phrases that would be valuable in the field. One of the lists is shown below:

Hurry! Isoge (or) Hayaku
Slowly Yukkuri
Dangerous Abunai
Stop (halt) Tomare
Don’t worry Shimpai shinade
Don’t shoot Utsu na
Be careful Chui nasai
Stand Tate
Good Yoshi
Raise your hands Te o agero
Come out raising your hands Te o agete detekoi
Come out (polite form used towards civilains) Detekinasai
Come follow me Tsuitekoi
Immediately Sugu ni
If you don’t obey we will fire Kikanaito utsuzo
Wait here Kokode matte
There is drinking water Nomimizu ga aru

One of the rules of psychological warfare is that you constantly test your propaganda on the enemy to find out if it was effective. Bob Sheeks seemed to figure this out on his own and prepared a Psychological Warfare Interrogation Guide for the interpreters with the concept that the answers would provide a basis for an estimate of the effectiveness of the PSYWAR program and provide data for preparation of further leaflets and broadcasts in the future. There are about 40 questions but I will just mention a few of the more interesting ones:

What lies were told by your superiors to encourage fighting morale or to discourage dissension?

Did you see any leaflets? Where? How many? Were you afraid to pick them up? Were there any official measures against the leaflets? What was your impression of the leaflets?

Did you hear any public address broadcasts? When? Where? What were your listening habits impressions? What measures were taken by your officers or NCOs to prevent surrender?

Did you see any patrol cards? Were you taken prisoner by our troops? Did one of their members load them to the side as directed by the patrol card?

What are your personal and general outlooks on postwar conditions?

What do you think about the Emperor, Tojo, the Army, the Navy, and your leadership?

The Marine Intelligence Section actually prepared a paper in the field on 5 February 1945 to be read to the Marines to explain the importance of taking prisoners. Titled “Know Your Enemy,” it said:

Prisoners, either civilian or military, are able to provide descriptions of anything they have seen or heard, and that can cover a very wide range of factual material. Information gained from prisoners has been and will continue to be vitally important in saving lives, saving time and wining a campaign…It is an interesting fact that despite the fanaticism which the Japanese soldier often displays, he is very often willing upon capture to tell the truth about a great many important things.

To illustrate the value of prisoner of war information, at Saipan, a military prisoner was able to indicate a tank park, a munitions and food dump, a watering place, several unit’s headquarters, and a sizable concentration of troops…vital Jap tanks, supplies and troops were knocked out of the picture. And commands were further scattered. All this without a single casualty to us….

Bob had spent all his funds but still needed the leaflets printed. He visited the Honolulu Advertiser, explained his problem and asked for help. The newspaper agreed to print the leaflets in color free of charge. Thousands of the leaflets were printed about 5 x 10-inches in size. Today there are PSYOP battalions with printing plants that could design, print and cut millions of leaflets in a day. Bob did the same thing on his own with a friendly newspaperman. What do we know about the Sheeks leaflets?

SheeksLeaflet001.jpg (118468 bytes)

One had the characters for “Common Sense” overprinted in red. The theme was “use common sense, don’t die uselessly." The leaflet described the defeat the Japanese were facing and asked why they must die for the mistakes of others. The leaflet ended with:

Let us use common sense and examine our respective realities. On land, you know that all roads are blocked. In the air, our planes are without opposition. Try as your Navy would like to, it cannot hope to bring help. Every avenue of escape is denied you.

You have fought well; no one could do more, or be expected to do more. Our artillery, mortars, bombers, ships all await only the signal to completely annihilate you. But, before your brave lives are exchanged for cheap shells, let us use common sense.

Are all those who have fought as well as possible to die like animals? Are all Japanese to die for the mistakes of others? What can dead men do? Does the dead blossom bear fruit?

Let the men of intelligence come forth! Come during daylight, singly, with hands up. Food, water, tobacco, and medical care await you. Act now! There is no time for waiting.

Although not involved with the American invasion of Saipan, the Australian Military Forces Weekly Intelligence Review from the year 1943-44 does mention the use of surrender leaflets there:

At the time of the attack when the Americans started to land on SAIPAN, one POW was told by a Hawaiian-born Japanese soldier that the Americans would treat him well if he were captured because they are a humane people. This contradicted what the POW had previously heard that Americans had tortured Japanese prisoners captured on GUADALCANAL and NEW GUINEA but accorded with the POWs conception of what Americans were like. At the time, however, the thought of becoming a prisoner did not enter his head.

Later in the war when Saipan became a giant forward propaganda base for the U.S. Navy and the Office of War information the same sort of leaflets were prepared, but reminded the Japanese that it was only their leaders that were to blame and they needed to live to rebuild Japan.

SheeksLeaflet002.jpg (145973 bytes)

Another leaflet was in the form of a personal letter from a Japanese soldier who had surrendered. It was addressed to “You troops who have fought bravely” and told of good life in an American POW camp. This leaflet ended with the comment:

To you troops who have fought bravely, it is my hope that you are well. I am a soldier just as you are, and am writing from an American camp among a great many others whose message is the same as mine.

Some of us came from the Marshall Islands, others from the Gilbert Islands. Many are from the Aleutians or New Guinea. We are what is left of units that were all over the Pacific.

Our life is good. Those who wish to work are paid a fair wage. Everyone receives excellent and healthy foods and medical care. There is recreation and study.

Just as crumbling Germany or Italy we can see that Japan is being encircled and is fighting a losing battle. Are those who have fought as well as humanly possible to die? Are all Japanese to die because the fleet and our forces can no longer fight back?

What part in culture or progress can dead men play? Food, drink, and good living conditions await you. We are all hoping that you will save your life. From a comrade in America

The idea of having prisoners write letters was used more in Vietnam than in WWII by American forces. However, there are dozens of wartime leaflets that show happy Japanese enjoying sports and music, playing board games and eating. The POW camp was made to look like a vacation resort.

Lying heaped in a shell hole, a large number of dead Japanese soldiers have yet to be buried. The Japanese mostly fought to the death on Saipan, perishing in pitched banzai charges or at the hands of American troops determined to capture the island despite the heavy resistance.

SheeksLeaflet003.jpg (92595 bytes)

A third leaflet had color as well as black. The characters for “Military Secret” were stamped at the top in bright red. It was written like a military field order. It pointed out that Japan was losing the war and this was a military secret that the Japanese troops were not to know. The secrets:

Your territorial and troop loses all over the Pacific have, until now, been kept a secret from you.

That you have fought well in spite of bad leadership, and that you are now being overwhelmed has been kept from you.

That we give you food, water, medical care, and tobacco has also been kept secret from you by lies and threats from your officers.

Come forth in daylight, singly, with hands up. You will be treated honorably and fairly.

Do not waste your life for lies.

The United States did not prepare leaflets like this later in the war, but it did print numerous newspapers that were designed to keep the Japanese up-to-date on how the war was going. It mentioned every Japanese defeat and every time the homeland was bombed by B-29s. Other later leaflets showed newspaper people or radio broadcasters gagged or with hands tied, unable to tell the truth because the Japanese military wanted to keep secrets from the public.

SheeksLeaflet004.jpg (106902 bytes)

The last leaflet in the Korean language script stressed the theme of independence from the Japanese. It mentioned the brutal occupation of Korea and exploitation of its people and resources. The Cairo Conference had already laid plans for Korean Independence after the Japanese defeat. There was also a red banner line of the name of a famous Korean battle for independence, “Kap O Nyen Nal Li.” Some of the text is:

Koreans! Why die for the Japanese?

You know well the story of Japan’s treacherous attack on Korea and of “March, the First.” Ever since then they have used all of you and your country as a great beast of burden.

Strike a blow now for Korean freedom! You have a chance now to free yourselves!

Come to our lines in daylight with hands up. Come singly, not in groups, and unarmed.

Koreans are not our enemies! Food, water, tobacco and medical we have here to share with you

For Korean independence the time is now!

[Note]: The March 1st Movement was one of the earliest public displays of Korean resistance during the rule of Korea by Japan from 1910 to 1945. The name refers to an event that occurred on March 1, 1919, hence the movement's name, literally meaning "Three-One Movement" or "March First Movement" in Korean.

[Note]: I asked some Korean friends about the Kap O Nyen Nal Li reference on the leaflet. Even they were confused. The best they could come up is Kap O Nyen is a year based on an ancient calendar system that means 1894. Nal Li means coup d'etat. Apparently there was a failed coup d'etat in Korea in 1894 led by Japanese opposition party against the Chinese rulers. The Koreans resented Kap O Nyen Nal Li because it was staged by a pro Japanese group and Japanese Ronins were hired to kill the Queen of Korea in that melee. This attempted coup led to a war Japan and China.

An interesting cartoon from that time. Japan and China fight over the body of a beaten Korea while Russia watches and waits in the background. The cartoon and many more were drawn by a French war correspondence named G. Bigot who was embedded with the Japanese Imperial Forces.

Later in the war, leaflets were prepared also for the foreign workers used by the Japanese and also told the Filipinos and Formosans that their freedom was assured. Toward the end of this article we will show some of the later leaflets that mention Saipan and the themes described above.

Once Lieutenant Sheeks had leaflets and loudspeakers in Hawaii, what to do next? He looked into using artillery shells or U.S carrier planes to drop the leaflet over the enemy. John Pelzel, Assistant Commander of the Intelligence section recommended using artillery spotter planes. Sheeks designed a system of placing about 100 leaflets in a brown paper wrapper, tied with a 15-foot string and throwing them from the aircraft. The string would be secured inside the aircraft so when the package got 15 feet away it would burst open. Since the spotter plane was looking for Japanese troops concentrations to call in fire, the leaflets would be sure to fall on the Japanese.

Sheeks also needed a jeep to carry the heavy loudspeaker, amplifier and generator. The Marine Corps provided the jeep and the system was fitted onto the vehicle.

The next project was messages to be broadcast. Later in the war, the U.S. would spend much thought trying to find a suitable term to use instead of "surrender." They came up with “I Cease Resistance” and this was used in all their broadcasts and leaflets. Sheeks came up with his own term, a simple “Come out.” The final effort was to convince Marine combat leaders that the Japanese would surrender. None of the sergeants and combat teams believed that the Japanese would surrender, but Sheeks at least put the idea in their mind that it could be worthwhile to try.

Bob Sheeks landed on Saipan with the first wave of Marines. Although he was an interpreter, every Marine is also a rifleman and so he landed on the beach.

His actual assignment was to read Japanese documents. On the side he arranged for his leaflet drops. It was unknown if the leaflets would work but it was worth the try. The answer appeared a few days later. Sheeks took his jeep to an area where the Japanese were hiding in caves and started to broadcast a “come out” message. A group of men, women and children emerged from a cave. Sheeks approached them and one of the men took out a piece of paper from a shirt pocket. He had hidden it for days since the Japanese would kill him if they saw it. When the chance arose, the group used the directions on the leaflet to surrender. The leaflets worked on civilians. A week later, using the same technique, a group of about 10 armed Japanese soldiers surrendered. The loudspeakers worked on the Japanese military. Some Japanese will surrender!

Lieutenant Sheeks is awarded the Bronze Star by General Watson,
Commandant of the 2nd Marine Division, for his actions on Saipan, August 1944

BronzeStarVSh.GIF (9371 bytes)

First Lieutenant Robert B. Sheeks was awarded the Bronze Star with “V” device in 1944. The citation said in part:

For heroic achievement as an interpreter of the Intelligence Section of the Second Marine Division, during operations against enemy Japanese forces on Saipan and Tinian, Marianas Islands, from 15 June to 1 August 1944. Pioneering in devising methods of directing combat propaganda at the Japanese prior to the Marianas Campaign, First Lieutenant Sheeks prepared several means of propaganda used during this campaign. When large numbers of civilians were driven into hiding by our advance during the latter stages of the operations, he moved with front line units despite considerable personal danger and utilized public address systems to call civilians and soldiers out of hiding, thereby effecting the surrender of large numbers of the enemy. By his ability, perseverance and devotion to duty, he materially reduced hostile resistance and upheld the highest traditions of the United States Naval Service.

I should note that as handsome as that Bronze Star medal is, it is the tiny “V” on the ribbon that makes it special. The medal can be awarded for administrative excellence and many other accomplishments, but that “V” for “Valor” indicates that the individual put his life at risk and earned the medal under combat conditions. A combat veteran will recognize that immediately.

The number of civilians that eventually came out of the mountains and caves is quite astounding. During the first weeks there were already several thousand civilians in in Camp Susupe. By the time things had settled down, 15,000 Japanese civilians, local Chamorro natives and Carolinian islanders came out of hiding.

One Japanese prisoner of war told the Australians what he thought about the propaganda leaflets on Saipan.

The POW believes that propaganda leaflets could have a good deal of effect if properly used and in sufficient quantity. He said that there were far too few leaflets on SAIPAN, that most of the troops had never seen any of them. The POW stated that it was extremely unlikely that any troops would surrender in the company of fellow soldiers but that it was probable that only men cut off from their units could be induced to give up, even by the most skillful leaflets. He thought that any believable propaganda would work but that it must be couched in immediate terms and not in the terms of general statements about wicked warlords. Leaflets which stated that the Japanese position was helpless, that the Japanese Navy would not help the troops, and material of a similar nature would be believed and would be effective under the conditions stated above. Leaflets attacking overall Japanese strategy, the military clique or the like would not be understood by most of the troops and would probably produce no results. The POW was most emphatic in stating that pictures of PW held by Americans would have a bad, even contrary effect, causing those who saw them to determine never to become prisoners themselves.

Sheeks went on to take part in further battles and in 1945 the Office of Strategic Services offered him a position in China, but his duties with the 2nd Marine Division did not allow him to accept the position. He later became the State Department's Information Officer on Taiwan and was recommended for the Commendable Service Award.

The battle for Saipan was bloody. The official statistics for American forces were 13,790 casualties: 3,426 killed and missing and 10,364 wounded. The Japanese military suffered 29,000 dead: 24,000 killed in action and 5,000 suicides. The Japanese civilian population on Saipan suffered 7,000 dead (many of which were suicides) and 22,000 other civilians killed.

One of the young Marines wounded during the fight for Saipan would later become a Hollywood legend, actor Lee Marvin. Marvin came ashore with Company I, 3rd Battalion, 23rd Marines on Yellow Beach 2. He said later:

During a firefight there are two parts of the body the enemy can pretty much see while hugging the deck, the head and the butt. If you present one, you get killed. If you raise the other, you get shot in the butt. I got shot through the wallet. I received my Purple Heart in a hospital on Guadalcanal. I got a permanent scar on my keister and a check once a month for life.

We said above that we would show some of the later leaflets designed by the U.S. Navy and the Office of War Information at Admiral Nimitz’s forward base of Saipan which opened February 1945, months before the end of WWII.

114Fuji.jpg (40450 bytes)

Leaflet 114a

We mention the Sheeks leaflet above where he talks about common sense and not dying uselessly. The same theme was used many times later in the war. Leaflet 114a depicts a Japanese mother and child in the forefront, dead Japanese soldiers behind her with what appears to be cherry blossoms, and the towering presence of Mt. Fuji in the background. Surprisingly, the leaflet is in black and white. One might expect such a picturesque scene to be in full color. The text is:


The question is whether or not the policy of aggression which the militarists took for the happiness and prosperity of the Japanese people has backfired. Although wars are supposed to bring happiness to the people, the more you fight the more unhappy you are. What is the meaning of this war, which continues to destroy your homeland? To die in battle for the cause of making your people unhappy is obstinate and foolish.

Now is the time to bring strong reason into play. Deliver your homeland. Deliver your compatriots who unwittingly seek the path of annihilation. Moreover, think profoundly of saving the lives of your comrades who are uselessly committing suicide and wasting lives that they should revere.

I should point out one curious fact. There are dozens of leaflets that implore Japanese troops not to commit suicide. But, I have never seen one in which a Japanese officer was asked not to commit suicide. It is just the opposite. There are some leaflets that point out the weaknesses of the officer corps and suggest that suicide would be their only honorable option.

OWI Propaganda Leaflets that mention Saipan

There are numerous propaganda leaflets that mention Saipan to show the Japanese that Americans are a kind people that follow the rule of law. Since the Japanese were told by their leaders that the Americans were mad-dog killers, psychological warfare was needed to convince the Japanese that they could safely surrender to the Americans. Here are some examples.

OWI Leaflet 409

Did American troops take skulls? Some did, but only a tiny number of the troops. I have mentioned in the past that I saw some skulls in tents, usually decorated with a cap or a pipe or cigar. Americans are great souvenir collectors and will also look for weapons, swords, flags, medals, or other items that show they were in warfare in a distant place and survived. Apparently, the Japanese told their men these stories to make them hate the Americans and fight to the bitter end. The military knew this and at least one leaflet was prepared on this very subject. The leaflet is very plain with no images. It was prepared to dispel Japanese beliefs of American cruelty. It is tiny by most standards, just 4 x 4-inches. The title on the front is:

In Memory of General Saito

The back is all text:

Your leaders and newspapers have accused us of sending home the skulls od dead Japanese soldiers and of making paper knives [Letter openers?] from the bones of corpses. Such statements are nothing but vicious lies. They have been told to you and your families at home to make you hate us.

When we found the dead body of General Saito on Saipan, we buried it with full military honors and fired a salute of 101 guns over the grave. Thus, we honored a fallen soldier. Is such treatment the conduct of barbarians?

The world is well-aware of the long history of American generosity. Don’t be deceived by lies!

Leaflet 412

This is a beautiful photograph filled with emotion. It is meant to illustrate the kind treatment American forces accord civilians in occupied territories. It depicts an American marine sharing his food rations and water with a Japanese child found in a pillbox on Saipan. The text on the back in a blue ink is:

On the reverse side is a photograph taken on Saipan shortly after the battle there ended. The boy and the American Marine are apparently good friends, and everybody is happy.

OWI Leaflet 500

This bright yellow leaflet depicts captured Japanese prisoners being treated well. They eat from heaping bowls of rice. Their faces are disguised to protect them. Later, after the Japanese claimed that these partially masked faces showed that they were not truly Japanese soldiers, the masks were removed so the prisoners could be clearly seen. The text tells the Japanese that their navy can no longer supply them. The leaflet’s purpose is to destroy the Japanese will to fight. The text on the back is:

Your navy abandoned your troops at Makin; it abandoned them at Tarawa: it abandoned them at Kwajalein; it abandoned them at Saipan, Tinian, and Guam.

It has now abandoned you! You are brave soldiers, but you can obtain no weapons or supplies and reinforcements. Join us and we will feed you and treat your wounds. We respect international law.

OWI Leaflet 509

This all-text leaflet assures Japanese civilians that they will be treated well if they surrender to American troops. It mentions the civilian suicides on Saipan. The text on the front is:

Japanese Civilians!

The text on the back is:

Despite what you have been told, Americans have no quarrel with civilians. On Saipan alone, 18,125 civilian men, children, and women came over to us and are now safe and happy under the kind care of Americans. Only a few who believed false stories of cruelty perished foolishly.

Do not believe falsehoods about American cruelty. See for yourselves. Select representative to come forward and observe the treatment they will receive. Then these representatives can return and guide you to safety. You will receive, food, water, clothing, and medical treatment.

Come during the daylight and wear white or colored clothes. We do not wish to mistake you for troops. Come quickly! You will be treated well!

514WWII.jpg (26072 bytes)

OWI leaflet 514

OWI leaflet 514 stresses the American military and industrial might. The leaflet is larger than usual at about 7 x 9.5 inches and printed in a bright red ink. The leaflet depicts a sky full of American aircraft and a sea full of American naval vessels all aimed at Japan. The purpose of the leaflet is to weaken Japanese morale by stressing American industrial and military might. References are made to America’s vast forces of men and equipment, and comments of prisoners of war are quoted generally to support the theme’s contentions. Text on the back is:

Powerful American forces, supported by innumerable planes, tanks, and ships, have already landed on your shores. Resistance against such overwhelming masses of men and equipment can only be futile. We know your valor, but you can't do the impossible.

As some of your soldiers who, at Tarawa and Saipan, expressed their thanks to us for fine medical treatment, admitted: "You Americans keep pouring in men and Materials. What can we do?" Yes, and this time we have even more than at Tarawa and Saipan.

515OWI.jpg (37022 bytes)

OWI Leaflet 515

Leaflet 515 shows the civilians of Saipan and a number of children who have surrendered and adds in part:

Japanese Civilians!

On Saipan, in addition to officers and men, 18,125 civilians accepted the generosity of the American forces. These civilians were given food, water, clothing, and medical treatment. You will be treated similarly if you come over to us. Do not believe the false stories that you will be mistreated and killed. If you destroy yourselves, you die in vain!

I mentioned above that Bob Sheeks used his own phrase substituted for "Surrender" to get the Japanese to leave their caves. It was simply “COME OUT.” By 1945 the USA was using “I Cease Resistance” on their surrender leaflets. 



Mariana News 2523

The OWI published many newspapers in Japanese, Korean, and Chinese. One of the papers that was read on Saipan was the Mariana News. This Japanese-language newspaper was first printed to give the Japanese homeland true news of Allied progress on all fronts. It was printed as a single sheet, 8 x 11-inches in size. This may be the most impressive single copy of the newspaper because it depicts Japanese ship under attack by carrier aircraft on the front, and the atomic bombing of Hiroshima on the back. Some of the other stories are Japan’s militarists resist peace terms, President Truman announces the dropping of the atomic bomb on Hiroshima, British fleet attacks Malaya, Kweilin recaptured, and the Japanese routed at Borneo. OWI files indicate that 50,000 newspapers were printed for each edition all coded in the 2500s. After the Americans took the island, this newspaper leaflet was produced on Saipan. The Japanese prisoners-or-war and civilians read this paper and it had a section just on Saipan. It was almost like a local newspaper for a small American town with tips and recommendations on things to do and what was happening. Some of the comments in the Saipan Military Government Camp News are:

2516 – Demonstrations and assemblies must have official permission. Worm eradication starts. Planting banana trees starts,
2518 – News reels to be shown at Japanese camp. Buddhist masses held. Military government relief work.
2520 – 127 children in new orphanage. Cautions about bathing in the sea. Take more care of ID cards.
2521 – Regulations for ration books. Hints for the home.
2522 – No outdoors after 2000. Red Cross presents for children. The library is crowded to capacity.
2523 – Best fishing spots. Health notes on the hookworms. Number of nurses now 30.

810WWII.jpg (155231 bytes)

OWI Leaflet 810

OWI Leaflet 810 is a safe conduct passes that instruct the Japanese how to come over to the American side. 810 is designed to affect a rapid surrender of Japanese troops and is entitled “Lifesaving guarantee.” The leaflet does not mention the word "surrender." It is printed with colorful red, white and blue stripes that make it visible for some distance. It was important that the passes be clearly marked because suspicious American soldiers were known to shoot first and ask questions later. The leaflet has the instructions in English on one side and in Japanese on the other.

I said above that the American POW camps were described as "resorts." Here is an example from the Army, dropped on the Philippines.

Japan18J1.jpg (179024 bytes)

Leaflet 18-J-1

Several American leaflets show the Japanese playing games such as Chess, Chinese checkers or Go. This leaflet shows some happy prisoners playing pool in an American prisoner-of-war camp in the Philippines. Some of the text is:

Yesterday [we were] Enemies, Today [we are] Friends.

Articles approved by the International Convention on treatment of prisoners of war, which was signed by 29 nations at Geneva on June 27, 1929 contain the following:

Prisoners of war shall be treated humanely

The food ration of prisoners of war shall be equivalent to that of the depot troops.

Each came shall possess an infirmary for the prisoners of war…

The faces of the prisoners were partially hidden to protect their families back in Japan. The Japanese implied that these were not real prisoners but American actors, so later photographs depicted the faces of the prisoners in entirety.

505CardOWI.jpg (146535 bytes)

Leaflet 505

This leaflet was aimed specifically at Koreans forced to work as laborers for the Japanese. The front page is in English and explains to the American soldier that the back page is in Korean and asks the reader to point out other Koreans who may be in hiding and bring them forward to the Americans. It was believed that the Koreans would be happy to escape the Japanese to the safety of the American lines. Notice that the title “Patrol Card” is identical to Sheeks card, and the last line, “Every prisoner turned in means the saving of American lives, time, and material,” is also identical.

By coincidence I found a mention of the Korean leaflets in some wartime files. Don Shively mentions propaganda leaflets in the US Navy Japanese/Oriental Language School Archival Project, THE INTERPRETER:

A few months later, I was back in Honolulu again, this time to assist in preparations for the Marianas Islands campaign, which work included composing propaganda leaflets in Japanese and Korean to be air-dropped on Saipan and Tinian. Otis and Frank Huggins assisted me by enlisting services of Japanese military POWs in the stockade at Pearl Harbor to help proofread and improve the texts.

JapaneseSuperSubmarineI15.jpg (23814 bytes)

Japanese Super-Submarine I-15

Although this story was about Lieutenant Sheek’s psychological operations to save American and Japanese lives, he later told me of a time when he was called to interview some Japanese sailors and that led to the discovery of super-class Japanese submarines that were attacking shipping and land targets along the U.S. West Coast. As usual, Bob took no credit for this discovery, but I thought I would add it here.

BatteryRussel.jpg (59004 bytes)

Battery Russell at Fort Stevens State Park

Few Americans remember, and many find it hard to believe, that Japan’s Navy dropped shells and bombs on the U.S. continent, and was sinking ships along America’s West Coast months after her carrier air strike decimated the U.S. Pacific Fleet at Pearl Harbor. The attackers were giant submarines, nine of which Japan deployed within days after Pearl Harbor along the coasts of California, Oregon and Washington, from San Diego to Seattle.They soon sank five U.S. ships and damaged five others. Submarine I-17 fired artillery shells, igniting oilfield installations near Santa Barbara, California in February 1942. Submarine I-25 shelled a coastal defense installation, Fort Stevens, near Astoria, Oregon in June 1942, and flew its aircraft twice in September 1942, dropping incendiary bombs to ignite fires in an Oregon forest.

How Japan had managed to launch the attacks remained unclear until halfway through World War II. In August 1943, Japanese submariners, taken prisoner after their vessel sank, divulged startling information during interrogation. Their giant I-15 Class ocean-cruising attack submarines had a previously unheard of range of 16,000 miles. Crewed by 100 men, these vessels carried one deck-mounted 5.5-inch cannon; machine guns; a catapult-launched scouting seaplane housed in a watertight hangar, and 17 torpedoes. Large as destroyers, they were 356 feet in length; displaced 2,584 tons submerged; and had a surface speed of 23 knots.

On 20 August 1943, Lieutenant Sheeks was on Noumea as part of Admiral Halsey’s headquarters translation staff with stacks of assorted Japanese papers awaiting translation: maps, combat orders, weapons manuals, unit records, hand-written diaries and letters. He was suddenly ordered to the prisoner stockade and found six Japanese submariners from the sunken Japanese submarine I-17.

After medical attention, camp uniforms, and a good meal were provided to them, each submariner was confined in solitary quarters to prevent collusion on replies to interrogation questions. None of the six was of officer rank, but Sheeks knew they would be well-informed. Even enlisted men in Japan’s submarine force were elite, selected from the best-rated, and most dedicated young volunteers; trained as rigorously as officers; and imbued with militaristic culture. None had ever been briefed about how to conduct themselves as prisoners, in event of capture and interrogation. Japanese military personnel were deeply indoctrinated with the creed that any Japanese who fails to commit suicide, permitting an enemy to take him prisoner would disgrace his family, dishonor his nation, automatically cease to be a Japanese citizen, and become an outcast never able to return home. While their indoctrination did strengthen the suicide resolve of some, it also backfired to the advantage of interrogators dealing with surviving Japanese military personnel. Sheeks told me how he used a little PSYOP on the prisoners:

To expedite interrogation, I found it effective to simulate the strict manner of a Japanese superior officer toward enlisted personnel. A single prisoner at a time under escort was marched into the interrogation tent for questioning.

An American Nisei sergeant assigned from the U.S. Army pretended to be my adjutant. He shouted commands in Japanese:




The prisoner invariably bowed, and remained standing rigidly at attention until dismissed. This established an atmosphere familiar to Japanese servicemen, most of whom would at some time have faced questioning by officers. Our aim was to take advantage of the almost ingrained Japanese servicemen’s reflex of replying to a senior officer without hesitation.

Interrogation began with name, rank, age, birthplace, education and unit designation. Less innocuous subjects followed, such as training for submarine service; combat experience; specialist duties; his submarine I-17’s performance capabilities; its guns, torpedoes, on-board seaplane; Pacific area navigation routes and refueling locations; identity of other, especially I-Class, submarines in the area. Most of the men initially tried to evade questions by claiming ignorance, or by falsifying information. Through repeated solitary questioning and constant cross-checking of previous interrogation notes, it was possible to establish facts, and then confront those who had not told the truth. This usually induced the holdouts to provide fuller and more accurate information.

We learned that eight other I-Class submarines were patrolling along America’s Pacific coast, sinking and damaging ships. Interrogation results, transmitted to Naval Headquarters at Pearl Harbor, resulted in a report that the U.S. Navy had intercepted and sunk one or two large Japanese submarines in the area, aided by information obtained from I-17’s crew prisoners.

Post-war reports confirmed that Japan built 26 submarines of this I-15 series, completing 7 before Pearl Harbor, the remainder during early years of the war. With the data gained by Lieutenant Sheeks and the use of the code-breakers reading Japan’s maritime mail, the super submarines were hunted down and destroyed.
