Hilaire du Berrier

He died on October 12, 2002 in Monaco. His papers covering the period 1935-1991 are stored with the State Historical Society of North Dakota.

Du Berrier appeared as himself in a 1982 documentary published by Western Goals Foundation titled No Place to Hide: The Strategy & Tactics of Terrorism, written, produced, and hosted by G. Edward Griffin and directed by Dick Quincer. He was interviewed on the attempted assassination of Pope John Paul II in 1981 by Mehmet Ali Ağca.

From 1958 until a few years before his death, du Berrier wrote articles for American Opinion magazine published by the John Birch Society and Review of the News published by Robert Welch, and its successor The New American. He was also associate editor of the John Birch newsweekly, Review of the News.

He published his monthly foreign affairs newsletter, H. du B. Reports, from June 1957 to May 2002.

In 1955 he attended the "Big Four" Geneva Summit as an advisor to the Vietnamese, according to his account. According to the historian Seth Jacobs, du Berrier worked with the Vietnamese emperor Bao Dai and was an advisor to Ngo Dinh Diem "until the premier began his antisect campaign, which du Berrier thought diverted attention from the communist threat". Jacobs credits du Berrier's 1958 "Report from Saigon" in The American Mercury with being the first description in American media of atrocities in Diem's police state, although du Berrier's influence was limited by his extremist politics to readers of far-right publications. Du Berrier also denounced the Diem regime in newsletters of the archconservative National Economic Council, in his own bulletin H. du B. Reports, and in letters to senators including Mike Mansfield of Montana (and after being rebuffed by Mansfield, he wrote a letter to Montana newspapers opposing the senator). An article in Reviews in American History describes du Berrier as "a far-right critic of the AFV", the American Friends of Vietnam.

He worked for the Office of Strategic Services briefly as an informant in Shanghai after the Japanese surrender in 1945. Also after the war he worked as a correspondent for Newsweek.

Du Berrier was captured in November 1942 by the Japanese and held in the Haiphong Road camp with other foreigners. He wrote that he was tortured in 1943 by the Japanese. He was awarded the French Cross of the Resistance Volunteer Combatant.

In wartime Shanghai, du Berrier was an Axis agent and a pimp, according to research described by the British historian Bernard Wasserstein. A 1941 Shanghai police report said that before World War II du Berrier had been an agent of the Japanese intelligence service. Initially during World War II, du Berrier attempted to join French and British forces but was rejected. Later, du Berrier wrote monthly articles for Klaus Mehnert's Nazi-funded XXth Century, published in Shanghai; du Berrier wrote to his sister in 1941 that he was embarrassed that it was an "Axis propaganda sheet" but he continued to work for it.

Living in London afterward, he caught the attention of British intelligence, which assessed that he was a "mercenary adventurer". Afterward, according to du Berrier, he traveled in Central Europe and the Balkans, representing a Dutch aircraft company, and then moved to Shanghai, China. He tried to sell aircraft in Shanghai but, according to his correspondence, the business flopped. After Japan's invasion of China in 1937, du Berrier volunteered for China's small air force, but his service was ended either with a crash or, as he wrote to his sister, with charges that he was spying for Japan.

According to du Berrier, he met exiled Spanish king Alfonso XIII by chance while walking down the Rue de Rivoli, and said he had a "lifetime follower" after that. He also joined the far-right Action Française movement. He moved to Monte Carlo where he managed a nightclub, and after it closed, he worked for a perfume business. His mother died in 1935, leaving him an inheritance.

In 1935, du Berrier traveled to Ethiopia to fight for Emperor Haile Selassie as a mercenary pilot. Italy invaded Ethiopia soon afterward. According to his writing, he was captured by Italian forces but escaped to Djibouti.

In 1931, du Berrier traveled to Paris with his uncle, a former congressman, who had been appointed a U.S. representative to the Paris Colonial Exposition. After arriving in France, he was given the registered name of Hilaire, which he went by afterward. He joined the social circle of the Lafayette Escadrille World War I pilots. His barnstorming career caught the attention of Charles Sweeny.
