The Bismarck in Battle. This photo is the most well known of the battleship Bismarck and one the most famous of World War II as well.
It was taken from the Prinz Eugen sometime between 0607 and 0609 hours on 24 May 1941.
By then the Hood had already been sunk and the Bismarck hit on her bows.
The after turrets "Cäsar" and "Dora" are firing against the Prince of Wales in one of the last salvoes of the battle.
Don't get confused, it's not at night, the brightness of the flash of the guns led to the darkened underexposure of the photo.
