  5. What happened? • In 1941 more ships were placed in convoys, that now escorted all the way across the Atlantic • By the help of developing technology the convoys routed around the Germans U-boats. • By the late 1942, the U-boats returned in larger number to the mid-Atlantic • They were searching for weakness in convoy defence, that could be exploded by “wolf packs” of U-boats • Britain lost ability to decode U-boat signals • They were too many U-boats to avoid • Britain again broke German codes • RAF agreed to help escort in the “black hole” • The Allies won the battle at a terrific price, and the food fuel and war supplies continued to flow throughout WWII

  6. Facts • Mainly between German U-boats and the British Royal Navy and the United States Navy. • The key for the Allied navies was to get supply convoys across the Atlantic Ocean, while the German navy, mainly with U-boats, tried to cut off Great Britain • Longest Campaign in WWII

  7. Why was this important for the Allies? • The Allies depended on the cross Atlantic convoys to get :- much needed supplies and food for Britain- the equipment that was used by the Allies in the battle- 60% of men (who were involved in war)

  8. Canada’s Role • Europe needed war materials made in North America, that came across the Atlantic Ocean on a ship • The ships were escorted by convoys. • Majority of those ships were part of the Royal Canadian Navy. • Men were shipped to Europe through the Atlantic • The winter caused a lot of problems , so in order to survive it the RCN escort ships needed to be tough and hard and determined • They did this for years and kept on getting better

  9. Significance of the battle • Britain (and the Soviet Union NEEDED supplies • Germany was attacking the supply ships (commerce raiding) • If the battle was lost, the Britain might not be saved

  10. Personal Diary “What a miserable, rotten hopeless life . . . an Atlantic so rough it seems impossible that we can continue to take this unending pounding and still remain in one piece . . . hanging onto a convoy is a full-time job . . . the crew is almost a dream from the night marishness of it all . . . and still we go on hour after hour.” -Frank Curry

  11. Political Cartoon This cartoon shows two boxers, one of them represents the 'ships' of the Allies and the other one symbolizes the German 'U-boats'. It depicts that the Allies' 'shipping' is losing and even though they are working on it…it still needs more help. This cartoon is encouraging people/politicians to help the Allies more.
