Lieutenant Berg, who was the German officer in command of the Appam after its capture, told the engineer on the second morning that he was then in charge of the ship, asked of him information as to fuel consumption, and said that he expected the engineer to help him all he could, and the more he did for him the better it would be for everybody on the ship. The engineer said he would, and did so. The engines were operated with a bomb secured to the port main injector valve, and a German sailor stationed alongside the bomb with a revolver. There was a guard below of four or five armed Germans, who were relieved from time to time, but did not interfere with the working of the ship. The German officer, Lieutenant Berg, gave directions as to working the engines, and was the only officer on board who wore a uniform.
