British sink the Bismark
Tuesday, May 27, 1941 www.onwar.com
In the North Atlantic... Rodney and King George V come up and in a gun battle lasting less than two hours, the Bismark is reduced to a hulk. She is finished off with torpedoes from the cruisers Dorsetshire and Norfolk.
In the Mediterranean... On Crete, German forces take Canea and Suda. The Allied forces are now largely split up and moving in a disorganized manner in the direction of Sfakia to be evacuated. The evacuation is authorized by Wavell after he has consulted with London. The battleship Barham is damaged by air attack.
In North Africa... Rommel has reinforced his troops on the Egyptian border and his two panzer regiments retake Halfaya Pass in a converging attack. The Germans begin work to fortify their new position, especially by digging in their 88mm guns.
In Iraq... British forces begin to advance from their positions around Habbaniyah and Fallujah toward the capital, Baghdad.
