The Black Prince (Armoured Cruiser, 1st Cruiser Squadron) was lost at Jutland, Admiral of the Fleet Sir John (later Lord) Jellicoe was the British C in C The Rodeny was not in the order of Battle, and I'm not sure if a ship of that name was in commission in 1916. The figure of 6000 lost (killed, wounded, and taken prisoner) is pretty accurate though (The official figure is 5914)
