In the lead up to, and throughout the Second World War, George McHale worked for MI6 when he met World War I veteran Indiana Jones, who had recently joined the Office of Strategic Services. On the time of their meeting, Indy's life was threatened by a luger and Mac somehow saved his life. Indy would owe him the favor ever since. During the war, Mac had a girlfriend named Penelope, and frequently he would give Jones an updated letter to deliver to her in case he was killed in the war. One such letter was written on D-Day (June 6, 1944).
