The Invaders #19

Captain America and the Destroyer covertly arrive in Berlin to see the Nazis parading the captured Invaders through the streets. Destroyer insists on using the time before their scheduled execution to plan a rescue, but when it looks like a trigger-happy guard is about to shoot Bucky, Cap blows their cover diving in to stop it. The skirmish ends with Captain America also captured and Destroyer seemingly killed in a grenade blast.
