Secret Sources on US Chemical Weapons in Asia and the Pacific during WWII

   Chemical weapons were very important in WWI, and both Japan and Italy used them in the late 1930s. During WWII, chemical weapons were available to both sides in massive quantities, but they were never used on the battlefield. Details of this chemical standoff remain important in 2023, partly to aid in understanding nuclear and other standoffs today and partly as a guide for dealing with old chemical weapons that still remain where they were left.
   The history of WWII's chemical weapons is elusive, however, since many of the original source materials were kept secret for many decades after the war's end, and some are still hidden away in the obscurity of archived microfilm vaults. Hoosier Scientist has obtained digital copies of two microfilm reels from the US Air Force archives at Maxwell Air Base and has posted complete "Organizational History Reports" for 3 Chemical Depot Companies.
   The 771st Chemical Depot Company (Aviation) maintained and later disposed of about 100,000 bombs containing mustard agent, lewisite, phosgene, hydrogen cyanide and cyanogen chloride at Ondal Advance Chemical Park in India. 771st-history-reports
   The Black enlisted men and White officers of the 769th Chemical Depot Company (Aviation) operated a front-line chemical stockpile at Kalaikunda, India, where they were ready to load chemical bombs onto B-29s. Those B-29s were part of Operation Matterhorn, the first bombing of Japanese home islands since the Doolittle Raid. 769th-history-reports
   The 760th Chemical Depot Company (Aviation) maintained a stockpile with about 25,000 chemical bombs, first in Queensland, Australia and later in New Guinea. The photos above show a map of their storage area in Queensland from 1944 and a photo from near their depot in New Guinea taken in 2023. 760th-history-reports
   Please consider investigating these original source materials for yourself. Let me know if you are interested in other aviation-related Chemical Depot Companies. I MIGHT be able to find their records on those two microfilm reels.

Morality of Wars, Past and Present

Secret document from June 19... Secret document from June 1945, documenting the role of the US Chemical Warfare Service in the bombing of Japan
Russian targeting of civilians in Ukraine has rightly caused outrage around the world. It is valuable to remember, however, that Russia is not alone in its willingness to target civilians as it seeks to achieve military or geopolitical goals. Other examples worthy of examination include the “rape of Nanjing” by Japanese soldiers in China and the British “counterinsurgency” tactics during the Boer War. Another example worthy of consideration is America’s strategic bombing of Japan during WWII. The 2 atomic bombs are well known, of course, but the firestorms which came first did far more damage and killed far more civilians. During the first months of 1945, soldiers like my father in the US Chemical Warfare Service were responsible for preparing and loading over 32,000 tons of incendiary bombs for use against Japan. Although napalm was the weapon of choice, the same bombs could have been filled instead with mustard agent or other toxic chemicals.

Hoosier Scientist has posted a 20-page, then-secret WWII document, “Chemical Warfare Digest,” from the US XXI Bomber Command. It details the ground preparations, designed to maximize the effectiveness of the firebombings as a way to force Japan to surrender unconditionally. It is important to realize that the most important “condition” of surrender that the Allies refused to discuss was for the Japanese Emperor to remain in power. During the war, the Allies insisted that Emperor Hirohito (like Hitler and Mussolini) had to be completely removed from power. After the surrender, however, the Allies chose to let Hirohito continue as Emperor.

What Secrets Did the Photographer Know?

thread
Major J. A. Philpott, Commandi... Major J. A. Philpott, Commanding Officer of the 490th Bomb Squadron, 341st Bomb Group and crew pose beside their plane at Ondal Airfield, India. 15 March 1943.
In mid-March of 1943, an unnamed US Army photographer visited Ondal Air Base, then under construction northwest of Calcutta in British India. He was a combat photographer with the 10th AAF Combat Camera Unit, but this was a noncombat project: accompanying an American Red Cross team as they opened “Club 690” for the base’s enlisted men. The photographer’s assignment, it seems, was to obtain pictures appropriate for release through US newspapers to inspire and reassure the American public. He completed that assignment, capturing newspaper-ready photos of heroic bomber crews, hard-working mechanics and more. He took other photos as well, some showing less pleasant realities of an American military base in colonial India. Twenty-six of his Ondal photographs (together with brief notes about each) are preserved in the US National Archives. Eighteen of the photos are available at https://www.hoosierscientist.com/ondalphotos

All wartime bases hold secrets. Some secrets involve military tactics, such as the struggle by B-25 bomber crews to find an effective technique for destroying the bridges they targeted in Burma. Other secrets were related to propaganda, such as the colonial government’s claim there was no shortage of food at a time when the price of rice was rising dramatically and the region was on the verge of a devastating famine. Ondal’s biggest secret in March of 1943, however, was both local and broadly strategic. The US was developing Ondal not just as a base for medium-range B-25 bombers but also as the site of Ondal Advanced Chemical Park. By early 1945, Ondal ACP would house a stockpile of nearly 100,000 mustard, phosgene, cyanogen chloride and other chemical bombs that could have been—but never were—delivered to the Japanese home islands on long-range B-29 bombers operating through China.

Which secrets, if any, do you think the photographer knew when he took his photos at Ondal?
