Footage of HMS Barham - 1941, being struck by torpedoes in the Mediterranean Sea, WW2

HMS Barham was struck by three of four torpedoes fired by U-331. Barham quickly capsized to port and was lying on her side when a massive magazine explosion occurred about four minutes after she was torpedoed and sank her. 862 officers and crew were killed, including two who died of their wounds after being rescued. The destroyer Hotspur rescued 337 survivors, including Vice-Admiral Henry Pridham-Wippell and the pair who later died of their wounds, while the Australian destroyer Nizam reportedly rescued 150 men. Captain Geoffrey Cooke went down with his ship. The sinking was captured on film by a cameraman from Pathé News, aboard Valiant.

Barham was struck by a three torpedo salvo from one u-boat, not three.

Where are you getting your information?

This is colorized and the history is incorrect. She was struck by a spread of three torpedoes from a U-boat. The ship rolled quickly, you can tell this by the smoke still pouring out of the stack, they didn't have time to shut the engines down. It it not known precisely what triggered the blast, but that explosion is orders of magnitude too large for a torpedo and it erupts from the center of the ship - that's her aft magazine going up. I think there were 859 men aboard and the escorts only found three survivors.
