His first target was the Wenton Aviaton Works, after they did that, they targeted the Boling Works. This failed miserably, after the Young Avenger crossed their plans, and defeated the sent saboteurs.
After hearing in the news, that the saboteurs were captured, von Himmel sent two of his henchmen, Otto and Hans, to watch on the walls after the Young Avenger. One of them was defeated but the other one captured him with gas and brought him, in chains, to von Himmel.
