Cap broke through Nazi troops for his final wartime confrontation with the Red Skull, who was seemingly slain by bombing debris (but lived on in suspended animation). Days later, Cap and Bucky arrived in England too late to prevent brilliant Nazi scientist Baron Zemo from obtaining and launching an experimental drone plane armed explosive device on it. Rogers and Barnes reached the plane, but when Bucky tried to defuse the bomb, it exploded in mid-air. Rogers was hurled into the freezing waters of the North Atlantic. The US government presumed both were dead. However, Bucky was secretly retrieved by Soviet operatives, while Cap was recovered by Nazi agent Lyle Dekker, who hoped to exchange bodies with him. Cap escaped Dekker’s base by air, but was shot down and fell back into the ocean. Due to the Super-Soldier serum Captain America survived, entering a state of suspended animation and eventually freezing in solid ice.
