"Mainz" was by now completely disabled. Her engines were stopped and her guns had ceased firing. Shortly before 14:00, came alongside and took off the wounded German sailors. At 14:10, "Mainz" rolled over to port and quickly sank at the position 53°58' N and 6°42' E; the survivors now in the water gave three cheers for their ship. The British rescued 348 survivors who were then taken prisoner; 89 men, including the ship's commander, were killed in the battle. Among the survivors was "Oberleutnant zur See" (Sub-Lieutenant) Wolfgang von Tirpitz, the son of "Großadmiral" (Grand Admiral) Alfred von Tirpitz, the architect of the German fleet. Tirpitz was picked up by a boat and taken to the light cruiser . Winston Churchill, then the First Lord of the Admiralty, informed Tirpitz via the United States' embassy in Berlin that his son survived the battle and had not been injured. In the course of the engagement, the British sank two more German cruisers—"Ariadne" and "Cöln"—with minimal losses to themselves.
