During the Second World War a fierce and decisive battle was fought on the world’s oceans and seas. Collectively it has become known as the Battle Of Atlantic. Winning this battle would determine the outcome of the war. The momentous responsibility of winning or losing WWII fell on Canada.
The Second World War would have been lost, if not for Canada’s early and continuous contribution protecting the convoys that carried the materials, fuel, munitions, weapons, food, etc. manufactured in Canada to the isolated island of Great Britain.
The opening shots of WWII were fired by German submarine U-30, two hours after war was declared, sinking the liner SS Athenia without warning, killing many innocent civilians.
Canada as a nation rallied to defeat the Nazi’s. Men and women turned Canadian industry into a massive war machine, converting factories that once made merchandise for sale in the stores to producing, weapons, tanks, aircraft, munitions, timber and every manner of equipment needed for victory. Farmers stepped up agriculture production, not just to feed Canada, but also the UK, starving from a naval blockade and the millions of soldiers, sailors and airmen that were needed to fight.
The determination to win the Battle of Atlantic started in the forests of British Columbia, farms on the prairies, factories in Ontario and Quebec, mines in the north and the rich fishing grounds of the Atlantic Provinces. To move these precious materials to England, Canada’s Merchant sailors took to their ships. The need for ships was so great that Lakers, designed to sail only on the Great Lakes were pressed into ocean service, while larger ships were built.
The danger these Merchant sailors faced began the moment they slipped their lines from Canadian ports at Halifax, Sydney, Quebec City and St. John’s, Newfoundland and headed to sea. They faced the best the German Navy had, surface raiders, battleships and cruisers, all with a simple order to defeat our forces by sinking merchant ships.
The greatest threat to Canada and our allies was the U-Boat! Germany deployed her submarines to sink merchant ships and starve England into surrender. They formed in groups, creating impenetrable lines across the ocean. A trap, that once sprung, brought down a pack of wolves onto the unsuspecting sheep. Hundreds of merchant ships were lost, killing thousands of merchant sailors. Great Britain was starving, at the height of the Battle of Atlantic; German U-Boats were sinking two to three merchant ships a day.
The Battle was not just fought on the ocean, the U-Boats penetrated Canadian waters, sinking twenty-three ships in the St. Lawrence River east of Quebec City and in the Gulf of St. Lawrence.
At the beginning of the war, the Royal Canadian Navy was small, a peace time force consisting of six destroyers, thirteen minesweepers and 2,000 sailors. Even with these limited numbers, the navy immediately formed the priceless merchant ships into convoys, escorting them to the UK.
As Canada mobilized her industry, a ship building program began, building larger merchant ships, frigates and destroyers on the Atlantic and Pacific coasts. In the Great Lakes a multitude of smaller ships were built, including corvettes, minesweepers, motor launches, trawlers, landing craft, rescue boats and tugboats.
Retired sailors, re-enlisted into the RCN, experienced merchant sailors and fishermen joined the Royal Canadian Navy Reserve (RCNR). Young men and women enrolled in the Royal Canadian Navy Volunteer Reserve (RCNVR) and the Women’s Royal Canadian Naval Service (WRCNS) enlisting in Naval Reserve Units across Canada. Over 100,000 Canadians joined the navy to fight at sea; many had never seen the ocean.
To meet the threat against Canada’s ocean trade, the RCN needed ships. At the beginning of the war private yachts and RCMP patrol boats were hastily turned into fighting ships and given names of Canadian animals. As the shipbuilding industry grew, the six destroyers, minesweepers and Animal class yachts grew to an imposing fleet of over 400 fighting ships, consisting of motor launches, minesweepers, corvettes, frigates, destroyers, cruisers and aircraft carriers.
Canada’s Navy had become the third largest navy in the world by the end of the war. RCN sailors were fighting in the Atlantic, Pacific and Arctic Oceans, The St. Lawrence, Caribbean, Mediterranean, North Sea, taking part in every major theatre of the war.
The Merchant Navy grew too. Hundreds of war measure merchant ships were constructed on both Canadian coasts, building the merchant fleet to the fourth largest in the world. For the over 12,000 Merchant Sailors, the war at sea was no different than their navy counterparts. The Merchant sailors and their big lumbering ships sailed alongside the sleek corvettes, frigates and destroyers into battle against the U-Boats. These civilian sailors paid a high price, with one in seven sailors killed.
Canada’s Navy did not fight alone. The Royal Canadian Air Force (RCAF) formed several squadrons of Maritime Patrol Aircraft. The Squadrons flew over the convoys and harbour approaches, hunting the U-Boats from the air. The Canadian Army built and manned shore defenses along the East Coast and harbours. Guns disguised into the country side, some camouflaged as churches, others buried into cliffs, ready to fire on any German surface raider or U-Boat that dared attack Canadian soil.
The battle at sea was fierce; Churchill himself stated his greatest fear was losing the Battle of Atlantic. This was the only battle during the Second World War that if lost, the entire war would be lost. Convoys of sixty or more merchant ships, escorted by navy ships would slowly sail across the Atlantic. At times as many as thirty U-Boats in Wolf Packs would swoop down for an attack, devastating the convoy.
Losses for Canada were heavy, thirty-three Navy ships were sunk, many more damaged, nearly 3000 men and women serving in the RCN, RCAF and Canadian Army were lost at sea. For the Merchant Navy, over one hundred ships were lost to the enemy, killing over 1600 Canadian and Newfoundland Merchant Sailors.
Early in the war, training for Canada’s novice sailors was “On The Job,” new ships went straight from the shipyard and joined the Battle Of Atlantic, often with disastrous results. With time, the skill and expertise of Canada’s sailors grew into a professional anti-submarine hunter/killer force. Turning the tide in the Atlantic, no more were the U-Boats having the success they enjoyed early in the war.
Canada was finally recognized for it’s overwhelming contribution in the Battle Of Atlantic when responsibility for all convoys, escorts and aircraft in the Canadian Northwest Atlantic Command was given to Rear-Admiral Leonard Murray, RCN in April 1943. Murray became the only Canadian to command a Theatre of War during WWII and became Commander-in-Chief of the area from the Gulf of Maine to Baffin Island, ranging out to mid-Atlantic.
As terrible as the losses for Canada were, our forces inflicted a heavy toll on the enemy. Jointly between the RCN and RCAF, over fifty U-Boats were sunk and many more damaged. Canadian Forces were also responsible for sinking and damaging a multitude of enemy merchant ships and warships.
In total, the Royal Canadian Navy escorted a staggering 25,000 merchant ship voyages from Canadian and American ports, successfully delivering 165 million tons of cargo, sustaining the war against the Nazis.
When history measures Victory from total enemy submarines and ships sunk, Canada’s contribution to the Battle Of Atlantic has not been properly recognized. Our Navy and Air Force were given a task that our Allies deemed insignificant in the ideology of Naval Warfare, the lowly responsibility of escorting merchant ships. World War Two did not become the Grand Fleet action, Battle Fleets slugging it out on the high seas for supremacy of the world’s oceans.
Instead it became a war of attrition on the high seas, single ship actions by “little” ships -destroyers, frigates, corvettes, minesweepers and motor launches supported by aircraft in the determined hunting and killing of submarines.
The major world navies had built their Grand Fleets of battleships, cruisers, aircraft carriers, and therefore lacked the ability to fight and win the real war. Canada in turn had hundreds of these little ships and this nation’s contribution to the Battle Of Atlantic turned the tide of the war, allowing the material to reach England.
- Without Canada, England would have been starved into surrender.
- Without Canada, there would not have been the planes, pilots, munitions and fuel to win the Battle of Britain, stopping the invasion of the UK by Germany.
- Without Canada, the Russian military would not have the tanks, weapons, aircraft to repel Germany’s invasion.
- Without Canada, there would not have been the landing craft, tanks, munitions and soldiers to invade North Africa, Scilly, Italy and Normandy.
- Without Canada, the material, weapons, soldiers would not have been available to liberate Europe and force Germany’s surrender.
History has recorded the Battle Of Atlantic as the longest single battle in the history of mankind. Beginning on 3 September 1939, two hours after war was declared, both Allied and Axis forces fought bitterly until the final minutes of the war, the last merchant ship, SS Avondale Park (Canadian Government Steamship Lines) was torpedoed by U2336 one hour before Germany’s surrender on 8 May 1945. The Battle Of Atlantic is the only battle that ultimately determined the outcome of the war.
If the Battle Of Atlantic had been lost, the Second World War would have been lost. Without Canada, the Battle Of Atlantic would have been lost!
