Minh government, and those south of the 17th parallel lived under the government of Ngo Dinh Diem. Hanoi and Haiphong remained free zones until May 1955. In August 1954, Dooley transferred to Task Force Ninety, a unit participating in the evacuation of over 600,000 North Vietnamese known as Operation Passage to Freedom. Here he served as a French interpreter and medical officer for a Preventive Medicine Unit in Haiphong. He eventually oversaw the building and maintenance of refugee camps in Haiphong until May 1955, when the Viet Minh took over the city. CIA recruitment and Deliver Us From Evil Dooley was assigned to the medical intelligence task force sponsored by the Military Advisory Assistance Group, whose leader, Lt. Gen. John W. O'Daniel, was an active ally of Ngo Dinh Diem. His official duties involved collecting samples for epidemiological work, "but his primary role was as a liaison between the refugee campaign...Operation Passage to Freedom and American reporters and politicians with an interest in Southeast Asia." In return for his work as a "spokesman", the doctor was awarded the highest presidential honor by Diem. During this period, he wrote numerous letters to his mother, many of which she shared with reporters; the letters were then printed in the local press, including the St. Louis Globe-Democrat. Most of the letters exaggerated his personal contribution to the refugee work. Despite his self-promotion, he "was indefatigable in taking care of his patients." Concerning the "self-aggrandizement" aspect of his personality, he said that to be a humanitarian in the modern world "you've gotta run it like a business. You've gotta have Madison Avenue, press relations, TV, radio...and of course you get condemned for being a publicity seeker"; he argued that being able to care for 100 people per day, between 1954 and 1958, with MEDICO later treating 2,000 per day, justified this approach to humanitarianism. Dooley was soon recruited as an operative by Lieutenant Colonel Edward G. Lansdale, head of the CIA office in Saigon. He was chosen as a symbol of Vietnamese-American cooperation, and was encouraged to write about his experiences in the refugee camps. The CIA, USAID, and several other agencies "conducted fund-raising campaigns for the refugees" later described in his books. The Pentagon Papers would later note that he "significantly aided" in the gathering of intelligence information. William Lederer, author of The Ugly American, helped initiate this phase of Dooley's career. Lederer,
