An operational necessity

It is January 5, 1945. A French freighter is torpedoed in the South Atlantic. By the laws of war, the shipwrecked survivors should be beyond further attack. But when the U-boat commander orders that they be shot, he justifies it as "an operational necessity." He believes that the safety of his own boat and crew depends on destroying all traces of the sinking. Only later, at an Allied tribunal after V-E Day, are the grim facts fully brought to light in a dramatic confrontation between the sole survivor and the captured German officers.
