The German battleship Tirpitz was sailing as part of a squadron under the command of Admiral Otto Schniewind to intercept convoy PQ 17 on 5 July 1942.
Notes on verification
Confirmed by multiple independent sources including Wikipedia, kbismarck.com's detailed operational history, and Warfare History Network, all consistent on Schniewind's command and the date.
