The Invaders #16

While in London, Bucky and Captain America fail to stop the abduction of American Private Biljo White by Nazi agents. White was the writer and artist of the comic book "Major Victory", the latest issue of which featured an origin story mirroring Captain America's. The Nazis evidently believed White knew details of the Super-Soldier Serum. Cap suspects he was taken to Hitler's armored fortress, Berchtesgaden, as various Nazi researchers had been sent there in the previous weeks. Arriving in Namor's airship, they are attacked and subdued by Master Man and imprisoned. Hitler arrives.
