In which military conflict was the U.S. 'Operation Flagpole' carried out?

'Operation Flagpole' was part of the run-up to 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.

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; Major General Mark W. Clark, United States Army; Brigadier General Lyman L. Lemnitzer, U.S. Army; Colonel Archelaus L. Hamblen, U.S. Army; Colonel Julius C. Holmes, U.S. Army; Rear Admiral Bernard H. Bieri, United States Navy; 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 to have Général Henri Giraud step forward and take command of French military forces in North Africa, and then arrange a ceasefire.
