Using a telephoto lens, Moffitt and Troy photograph a map inside Captain Dietrich's office from the roof of the adjoining Nazi HQ. It shows the location of a top-secret German ammo dump. The Patrol must reach the site, enter it, and destroy it before half of the German army arrives. The Patrol arrives to find the storage area--an old mine--surprisingly deserted. They plant the explosives, but just before they blow it, Dietrich (who has laid this all out as a trap) turns up. Shots are exchanged, and Dietrich and Troy are trapped inside. Meantime, outside the mine, assuming that the cave-in killed Troy, Moffitt and the Patrol prepare to finish blowing it up. Working together, Troy and Dietrich escape through a back entrance moments before the dump blows.
