Explosions, especially big ones, are horrendously nasty. The the link below is to footage of HMS Barham’s ammunition magazine exploding following a U-Boat torpedo attack will stay with you, I’m afraid. The battleship was attacked by U-331. She was hit by three torpedoes simultaneously. 4 minutes later her magazine exploded, due to a fire from the outer magazine spreading to the main magazine. Amazingly about a third of her crew survived, but well over 800 of the crew perished. The event occurred off the coast of Egypt in November 1941.
(Just being careful about licenses go to You Tube and enter HMS Barham.)
There are some interesting details on the HMS Barham association website here.
War is awful, don’t forget.
