Desperation leads to innovation in wartime. In 1942, the Allies were desperate because they were losing the war. Japan was winning in the Far East, the Afrika Korps was winning in North Africa, and the Wehrmacht had reached Stalingrad. U-boats were sinking supply ships in the North Atlantic.
In desperation, Britain and the U.S. decided to create a unique commando force, consisting of Canadian and U.S. soldiers. They gave it an innocuous sounding name, First Special Service Force (FSSF). Robert T. Frederick was appointed commander. He was a West Point graduate with a reputation for being opinionated but having a flair for organization.
