Toward the end in Saigon, the Defense Attaché, U.S. Army Brigadier General Homer D. Smith, named his deputy, Air Force Brigadier General Richard M. Baughn, to set up, control, and run the evacuation. His organization included the Evacuation Control Center, the Evacuation Processing Center, and the Evacuation Council. Around the middle of April, when the crowds of refugees thickened outside the Defense Attaché Office (DAO) compound at Tan Son Nhat, on the northern edge of Saigon, General Baughn cabled a request for additional security. Furious, the Ambassador, Graham Martin, ordered Baughn to leave the country.
As a result, the Special Planning Group (SPG), set up to oversee the evacuation of the DAO compound, “went black,” that is, proceeded with its work in strict secret from everybody save General Smith and his immediate evacuation planners. Despite the Ambassador, the preparations General Smith ordered for the evacuation continued.
The episode, including the SPG’s secret callsign, ALAMO, are reported in Last of the Annamese. Like Chuck in the novel, I was unaware that moves were underway to get us out of Saigon safely. I learned what was afoot during the final days when Marine Colonel Al Gray appeared at my office door one night in mufti (civilian clothes). He’d flown in from the 7th Fleet, operating in the South China Sea.
I am eternally grateful that General Smith in effect disobeyed the Ambassador and that the military side of the U.S. government—the Department of Defense and Command-in-Chief, Pacific—harbored no illusions about what was happening Vietnam. They took action. Had they not, my two communicators and I would at worst have been killed and at best been taken prisoner.
