The Battle of the Last Panzer (1969)

The Allied D-Day invasion is a success, and German forces begin leave Normandy. After an ambush takes out a set of Panzer tanks led by German Lt. Hunter, he finds himself alone with his unit in what may be the last Panzer that's still operational. While traveling through the French countryside, Cooper meets Jeanette, a woman who offers to lead the troops back to Germany, but his feelings for her get in the way of his survival instincts.
