Career
The 1940 U.S. census lists Archimedes' profession as "Special Agent, U.S. War Department" and in 1941 he joined the U.S. Army and served in Europe. In Europe he was in contact with various anti-Axis resistance organizations including groups in North Africa, Italy, and Yugoslavia. He was later transferred to the Office of Strategic Services in China, after unknowingly volunteering for the mission in January 1944 while on assignment at Anzio with William J. Donovan, the Director of the OSS.
During his career in China and Southeast Asia, Patti met Hồ Chí Minh, the leader of the Việt Minh and future leader and national hero of North Vietnam. In later interviews Patti explained that his mission in Vietnam was to establish an intelligence network but not to assist the French in any way as they attempted to re-gain control over their former colony, a policy choice he believed to be linked to U.S. President Franklin D. Roosevelt's belief in the self-determination of all peoples. Archimedes, did, from a distance, help organize, train and equip the fledgling Vietnamese forces Ho was uniting and marshaling against the Japanese, which in the future would be known as the People's Army of Vietnam, and worked closely with Ho Chi Minh and, indeed, commented on his early drafts of a Vietnamese constitution. Patti stated that when he arrived in Kunming in March 1945, the French colonials were either unwilling or unable to assist him in establishing an American intelligence network in Indochina and he therefore turned to "the only source ", the Việt Minh. Patti was introduced to Ho Chi Minh by Colonel Austin Glass, the OSS expert in Indochina. Patti met Ho Chi Minh on the Indochina-China border at the end of April 1945, and he agreed to provide intelligence to the allies provided that he could have "a line of communication with the allies." Patti later helped coordinate some small attacks against the Japanese Imperial Army using a small group of operatives known as the OSS Deer Team under the command of Major Allison K. Thomas, who worked directly with Ho Chi Minh during the August, 1945. On August 22, 1945, Patti arrived in Hanoi on a mercy mission with OSS agent Carleton B. Swift, and a French government official, Jean Sainteny. His mission primarily was to assist in the repatriation of allied prisoners of war as the U.S. government feared reprisals against them by the Japanese following the Atomic bombings of Hiroshima and Nagasaki and, secondly, to gather intelligence. Patti met with Ho Chi Minh on August 26, 1945, over lunch at his residence in Hanoi and several days later Ho Chi Minh read a draft of the Vietnamese Proclamation of Independence to him and Patti offered several corrections on what he perceived to be a near exact copy of the American Declaration of Independence. Indeed, Ho Chi Minh had requested an actual copy of the American Declaration of Independence from Col Austin Glass. Soon afterwards, on September 2, 1945, Ho Chi Minh declared independence and some hours later Patti had dinner with him. In the fall of 1945 French Colonial forces had returned to Indochina on U.S. manned Liberty ships. Patti left Hanoi at the end of September 1945, following French allegations that the Americans had been fomenting a revolution there.
Patti retired from the military in 1957. For 13 years, he was a crisis management specialist in the Office of Emergency Planning in Washington, D.C. In 1981, Patti stated that Julia Child, who had worked at the OSS during 1945, had allegedly submitted his position papers on Vietnam to appropriate authorities, but that the way in which he had found them upon retirement was exactly as she had sent them and that they had never been opened or read. In retirement, he wrote a book and several articles on Vietnam. In 1980, he wrote "Why Vietnam?: Prelude to America's Albatross," which describes his relationship with Communist guerrilla leader Ho Chi Minh during the mid-1940s. He died on April 23, 1998, at the age of 84. He is buried at Arlington National Cemetery.
