Operation Judgement, May 4, 1945, an attack on the U-boat base at Kilbotn, near Harstad, Norway. This proved to be the last offensive operation by the Home Fleet, as the war in Europe ended just a few days later.
<p>The main targets of the attack are, in fact, hidden behind water columns and smoke in the center of the photo. They were the depot ship Black Watch and the Type VIIC submarine U-711 — they were both sunk. The ship visible in the center of the pic is in all probability the motor vessel Senja, also sunk in this attack but raised and repaired after the war. U-711 was the last U-boat sunk by the Fleet Air Arm in WW2.

The attack was carried out by Avenger torpedo-bombers and Wildcat fighters from Squadrons 846 (HMS Trumpeter, Capt. K. S. Colquhoun), 853 (HMS Queen, Capt. K. J. D'Arcy), and 882 (HMS Searcher, Capt. J. W. Grant).
