9.  Attacking on the surface at night (where they could not be detected by Allied sonar, or ASDIC), U-boats had great success against Allied convoys, sinking merchant ships with torpedoes and then submerging to evade the counterattack by escorting warships. They were also benefitting from decoded communications of the British Admiralty. In 1941 they inflicted huge losses, sinking 875 Allied ships. Hitler’s Plans ("Battle of the Atlantic." HISTORY.

10.  The ‘hedgehog’ depth-charge mortar was just one innovation that was making life more and more dangerous for U-boat crews. By ‘Black May’ of 1943, U-boat losses were unsustainable – one quarter of their strength in one month, and almost at the same rate as Allied shipping. U-boats were withdrawn from the Atlantic, and the battle was won. Hedgehog ("Battle of the Atlantic." HISTORY. N.p., 01 Apr. 2014. Web. 21 Jan. 2015.)

13.  Allied victory in the Second World War would not have been possible without victory at sea. It would require overcoming great odds, but the courage of the RCN, Merchant Navy and RCAF personnel helped keep the Allied convoys running and the supply lines to Europe open. These brave men and women were some of the more than one million Canadians who served in the cause of peace and freedom during the Second World War. Significance ("The Battle of the Atlantic."
