During World War II, the Royal Canadian Navy (RCN) played a significant role in the Allied effort, particularly in the Battle of the Atlantic. The RCN's primary role was to escort convoys across the Atlantic and to protect them from German U-boats, which were a major threat to Allied shipping.

At the start of the war, the RCN had only 13 combat ships and 3,500 personnel. However, over the course of the war, the navy expanded significantly, adding new ships and personnel. By the end of the war, the RCN had grown to

become the third largest naval force in the world, with over 100,000 personnel and a fleet of over 400 ships.

The RCN's role in the Battle of the Atlantic was crucial to the Allied victory. Canadian ships escorted convoys across the Atlantic, providing protection against U-boat attacks. The RCN also played a key role in the development of new anti-submarine warfare tactics and technology, such as sonar and depth charges, which helped to turn the tide against the U-boats.

In addition to its role in the Battle of the Atlantic, the RCN was also involved in a number of other operations during the war. Canadian ships played a significant role in the invasion of Normandy in 1944, providing naval gunfire support and escorting landing craft. The RCN was also involved in operations in the Mediterranean, the Pacific, and the Arctic.

One of the RCN's most significant battles during the war was the Battle of the St. Lawrence, which took place in the Gulf of St. Lawrence and the approaches to the St. Lawrence River. German U-boats targeted Canadian shipping in the area, sinking several ships and causing significant damage. The RCN responded by increasing patrols and escorting convoys, and ultimately succeeded in protecting the vital supply lines to Canada.

Overall, the RCN played a crucial role in the Allied effort during World War II, particularly in the Battle of the Atlantic. The navy's expansion and modernization during the war helped to establish it as a professional and capable force, and laid the foundation for its continued growth and development in the post-war period.
