An operation to smuggle the anti-Vichy General Henri Harove' Giraud from Vichy occupied France to Gibraltar, to rally French North African Forces to the allied cause. He would only co-operate, if the allies pledged him a command in keeping with his rank and reputation.

He also refused to co-operate with the British, and would only travel in an American Submarine. In consequence, Seraph became American in all respects, under the command of Captain Jerauld Wright U.S.N., causing Seraph to become known as the "Ship with two Captains".

A ruse-de-guere to fool the Germans about the allied plans in the Mediterranean regarding the invasion of Sicily. Seraph took the unidentified body of a man dressed in the Uniform of a Royal Marine Major to the coast of Spain and dropped him close inshore, so that he would eventually wash up on the beach. It was hoped that the false papers in his briefcase would be found by the "neutral" Spaniards, who would transmit their contents to Germany.
