At some night in the ends of 1942, the German submarines fleets of the South Atlantic received urgent order for drive at all speed to an encounter point in Dakar. Few days later, a very superior number of those submarines outlined the western tip of Africa.

The force of American invasion that crossed the Atlantic would fall into a disastrous ambush. That was the opinion of the German High Command.
