Kelly's Heroes (1970)

During World War II, German Colonel Dankhopf (David Hurst) is captured by the Americans, but before he can be interrogated, an artillery barrage hits the camp. However, Lieutenant Kelly (Clint Eastwood) manages to reach the Colonel, get him drunk, and learn that he is on a secret mission to ship sixteen million dollars of gold to a base in France. Kelly is determined to get the gold, and plans for himself and a few of his fellow soldiers to slip into enemy territory and steal the bullion.
