With the opening of our Snoopy and the Red Baron exhibition, we’ve been thinking about who the real flying aces of the First World War are. And who was the Red Baron? Read on to find out what defines a “flying ace,” who Canada’s World War I flying aces were, and learn about the German ace known as the Red Baron.
Canada and the First World War in the air

Aeroplanes contributed to military success during the First World War and grew in importance as the conflict wore on.
Before the First World War, Canadian political and military leaders were sceptical about investing in aircraft as a weapon of war. However, leaders in Great Britain saw the potential for the flimsy devices made of wood, fabric and wire that could barely fly 100 miles per hour and created the Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS). In 1918, the RFC and RNAS were combined to create the Royal Air Force (RAF).
After war was declared in 1914, citizens of the British Empire flocked to Great Britain to fight in the air, on the ground and at sea. Canadians who did not want to join the army or the navy had to pay their way to learn how to fly and then travel to Britain to join the RFC or RNAS.
More than 22,000 Canadians served in the RFC, RNAS and RAF, over 13,000 of whom were aviators—pilots, gunners, or observers. The remainder served as ground crew—mechanics and support personnel. By the war’s end, Canada boasted some of the British Empire’s greatest flying aces, including Billy Bishop, William Barker, and Raymond Collishaw.

Flying in combat during the First World War took immense courage because flying a slow, flimsy, and flammable aeroplane was a perilous activity. First World War aeroplanes were not armoured against bullets and fires were deadly. For most of the war, aircrew could not wear parachutes. Aeroplanes suffering mechanical failure or damage required an emergency landing, often behind enemy lines. Almost 1,400 Canadian aviators are known to have been killed, 1,100 were wounded or injured, and close to 400 were interned or became prisoners of war.
Who was the Red Baron?
Baron Manfred Albrecht Freiherr von Richthofen was born in 1892 in Prussia (now Poland). After completing military cadet training, he joined the 1st Emperor Alexander III of Russia Uhlan Regiment (1st West Prussian). Following the start of the First World War in 1914, he saw action on both the Eastern and Western Fronts and received the Iron Cross for his courage under fire. Disillusioned and restless after his unit was assigned to supply duty in the trenches in 1915, he joined the Imperial German Army Air Service.
In January 1917, with 16 victories to his credit, Richthofen was awarded the Pour le Mérite (Blue Max), the highest military honour in Germany at that time. In July 1917, he sustained a serious head wound. Despite concern that his death would undermine the morale of the German people, he refused to accept a ground job and returned to flying duties.

Richthofen was a brilliant tactician who led by example. When given command of fighter squadron Jasta 11 in 1917, he had his aeroplane painted red so that “absolutely everyone could not help but notice [his] red bird.” He was thereafter known as the Red Baron. Following his example, the pilots he led also painted their aeroplanes in bright colours. By 1918, Richthofen commanded a four-squadron fighter wing, Jagdgeschwader I. It was known as “The Flying Circus” because of its brightly painted aeroplanes and rapid and frequent transfers to hotspots along the Western Front.
The Red Baron’s Last Flight
The Red Baron flew his last mission on 21 April 1918, when the Flying Circus engaged No. 209 Squadron of the Royal Air Force over the Western Front. When future Manitoban ace Wop May attacked Wolfram von Richthofen, the Red Baron flew to his cousin’s defence. When the Red Baron chased May down to ground level, future Canadian ace Roy Brown joined the fray to help his former school friend.
After Brown’s attack, the Red Baron resumed his pursuit of May. As their low-level battle took them over the trenches, Australian machine gunners on the ground fired at Richthofen’s conspicuous red aeroplane. The Red Baron’s last mission ended when he crashed near the Australian trenches. He was 25 years old. He is credited with 80 victories, the highest tally amongst all German pilots and eight more than the Canadian Billy Bishop, the RAF’s highest-scoring ace.
The RAF credited Roy Brown with shooting down the Red Baron; however, when Richthofen’s body was examined, it was determined that the Australian gunners most likely fired the bullet that killed him.
WWI Canadian aces
To be declared an “ace”, a pilot had to destroy at least five enemy aeroplanes or balloons in battle. Of the 863 known British Empire aces, at least 171 were Canadian. Of the 26 empire aces credited with 30 or more victories, 10 were Canadian.

William (Billy) Avery Bishop was the top-scoring ace from the British Empire, with 72 victories. During the Second World War, Air Marshall Bishop served as Director of Recruiting for the Royal Canadian Air Force (RCAF) and was involved in setting up and promoting the British Commonwealth Air Training Plan (BCATP). After the war, he contributed to the creation of the International Civil Aviation Organization (ICAO). Bishop died in September 1956, aged 62.
Raymond Collishaw is credited with 61 victories. He was the highest-scoring ace in the Royal Naval Air Service (RNAS). After the war, he joined the Royal Air Force (RAF) and saw action in Russia. He rose in rank to command No. 204 Group RAF during the Second World War. He retired in 1943 and worked in the mining industry. Collishaw died in 1976, aged 82.
Donald Roderick MacLaren is credited with 54 victories. After the war, he commanded all Canadian pilots in Britain. He resigned from the Canadian Air Force (CAF) in 1921 and worked to establish civilian air services in British Colombia. MacLaren died in 1988, aged 95.

Manitoban aces during the First World War
22,000 Canadians served in the Royal Flying Corps (RFC), the Royal Naval Air Service (RNAS) and the Royal Air Force (RAF) during the First World War. Of the 171 Canadian aces, 21 were born in Manitoba or emigrated to Manitoba before the war. Seventeen survived the war, of which four were captured and became prisoners of war (POW), and four were killed in action (KIA).
William George Barker was born in Dauphin, Manitoba in 1894. In high school, he joined the 32nd Light Horse in Roblin. In October 1918, he won the Victoria Cross for his bravery during his last dogfight when he engaged at least 15 German fighters. He shot down four but was wounded severely. His tally for the war was 50 victories, the fourth most amongst Canadian aviators. He was also awarded two Silver Medals for Military Bravery by Italy, and the Croix de guerre by France. Barker returned to Canada in 1919 as the most decorated Canadian in the war. After the war, he started a flying boat service with Billy Bishop, served as the first director of the RCAF, and was the first president of the Toronto Maple Leafs hockey club.
