General Events during this patrol


3 Nov 1940. At 2250hrs on 3 November, 1940, one of the most dramatic battles of the U-boat war began. U-99 attacked the armed merchant cruisers HMS Laurentic and HMS Patroclus. They were both sunk within seven hours, during which the U-boat fired ten torpedoes and four rounds from the deck gun, while the vessels returned fire without damaging the U-boat.
