What mysterious cargo does Captain Mueller deliver to Stalag 13, which Hogan and his crew take and replace?

Captain Mueller delivers a truck full of mysterious water, which the prisoners believe to be just water. Ultimately, Hogan discovers that it is water, but it is specifically a form of heavy water that the Nazis want to use in nuclear weapons testing. Hogan and his men then have to find a way to replace the barrel, which they do.
