Operation Flagpole was part of the run-up to Operation Torch, the planned Allied invasion of North Africa during World War II. It involved arranging for and carrying out a top-secret high-level meeting between U.S. General Mark W. Clark, representing the Allies, and Général Charles E. Mast, the leader of a group of pro-Allied Vichy France officers in French North Africa, to secure their cooperation with the invasion. Planning On October 16, 1942, a meeting was held in Operation Torch's staff headquarters at Norfolk House in London. Among those present were: Lieutenant General Dwight D. Eisenhower, United States Army, the Allied commander for Operation Torch Major General Mark W. Clark, United States Army, the recently appointed deputy commander for Torch Brigadier General Lyman L. Lemnitzer, U.S. Army, head of the allied force planning section for Torch Colonel Archelaus L. Hamblen, U.S. Army, the staff expert on shipping and supply Colonel Julius C. Holmes, U.S. Army, head of civil affairs branch for Torch Rear Admiral Bernard H. Bieri, United States Navy, senior U.S. naval representative Captain Jerauld Wright, U.S. Navy, liaison officer with the Royal Navy Eisenhower informed the group that the War Department had forwarded an urgent cable from U.S. diplomat Robert D. Murphy of the American consulate in Algeria requesting the immediate dispatch of a top-secret high-level group to meet with Général Charles E. Mast, the military commander of Algiers and the leader of a group of pro-Allied officials in French North Africa. The objective of this secret mission, code-named "Operation Flagpole", was to reach an agreement through Mast and his colleagues to have Général Henri Giraud, a key pro-Allied French army officer, step forward and take command of French military forces in North Africa, and then arrange a ceasefire with the Allied invasion force. Other alternatives, such as Jean Darlan and Charles de Gaulle, had been rejected by the British and American governments for a variety of political reasons. Clark would be Eisenhower's personal representative, with Lemnitzer as the top invasion planner, Hamblen as the invasion's logistics expert, and Holmes serving as translator. Wright would serve as the liaison with the French Navy, with the specific objective of convincing the French to have their fleet anchored in Toulon join the Allied cause. Execution The group flew in two Boeing B-17 Flying Fortress bombers to Gibraltar, operational headquarters for the invasion, and on October 19, they boarded the British S-class
