Official Caption: "CLAMBERING INTO CAPTIVITY: Nearly an hour after he slipped through the sinking U-boat's escape hatch, the jaws of this Nazi are still clamped on his artificial lung. He is one of 22 prisoners taken aboard a Coast Guard combat cutter after a second Coast Guard cutter had sunk the German sea marauder in the mid-Atlantic action. The Coast Guard craft were protecting a convoy and intercepted the U-boat as it attempted to slip within torpedo range of the Allied merchantmen."
