During the battle which followed their arrival on the scene, Black Prince seems to have lost contact with the remaining British Fleet; she was last heard of at 8.48 when she sent off a signal to say there had been a submarine sighting. It was beginning to get dark by now and so much was happening that other British ships had no time to look out for her.
So we look to the German account which says that just before midnight, the Black Prince approached the German lines, possibly thinking their outlines were those of British vessels. At some point, the Captain seems to have realised his mistake and ordered his crew to turn Black Prince round but by that time he had been spotted from the German battleship Thüringen which immediately switched on its powerful spotlights and opened fire. There were five more German ships all within a range of 1000 yards and all of them joined in the bombardment.
And now at last we can find an eyewitness account from a member of crew on board HMS Spitfire:
"We were just recovering from our ramming match with the German cruiser, and most of the ship's company were collected aft, when suddenly there was a cry from nearly a dozen people at once: "Look out!"
I looked up, and saw a few hundred yards away on our starboard quarter, what appeared to be a battle cruiser on fire, steering straight for our stern. To our intense relief, she missed our stern but just by a few feet; so close was she to us that we were actually under her guns, which were trained out on her starboard beam, She tore past us with a roar, rather like a motor roaring up a hill in low gear, and the very crackling and heat of the flames could be heard and felt. She was a mass of fire from fore-mast to main-mast, on deck and between decks. Flames were issuing out of her from every corner.
At first sight she appeared to be a battle cruiser, as her funnels were so far apart but afterwards it transpired that she was the unfortunate Black Prince with her two centre funnels gone. Soon afterwards, soon after midnight, there came an explosion from the direction in which she had disappeared."
