Question: Captain George Edwin Thomson, was a Scottish World War I flying ace credited with how many aerial victories, and one of the leading Sopwith Camel aces?
Context: Lieutenant Merrill Samuel Taylor was a Canadian flying ace during World War I.  He was credited with seven aerial victories while flying a Sopwith Camel fighter for the Royal Naval Air Service, and later, the Royal Air Force.  He touched off the air battle that resulted in the death of the war's leading ace, Manfred von Richthofen, on 21 April 1918.  On 2 May 1918, he killed German ace Hans Weiss for his fifth victory.  Taylor was killed in action by Franz Büchner on 7 July 1918. Otto Kissenberth (26 February 1893 – 2 August 1919) was a German flying ace of World War I credited with 20 aerial victories.  He was a prewar mechanical engineer who joined the German air service in 1914.  After being trained and after serving as a reconnaissance pilot, he became one of the first German fighter pilots, flying with "Kampfeinsitzerkommando" (Combat Single-Seater Command) KEK Einsisheim.  He scored six victories with this unit as it morphed into a fighter squadron, "Jagdstaffel 16".  His success brought him command of "Jagdstaffel 23" on 4 August 1917.  He would run his victory tally to 20, downing his final victim using a captured British Sopwith Camel on 20 May 1918.  Nine days later, a crash while flying the Camel ended Kissenberth's combat career.  His injuries were severe enough he was not returned to combat, instead being assigned to command Schleissheim's flying school.  Although Otto Kissenberth survived the war, he died soon after in a mountaineering accident on 2 August 1919. Richard Pearman Minifie, (2 February 1898 – 31 March 1969) was an Australian fighter pilot and flying ace of the First World War.  Born in Victoria, he attended Melbourne Church of England Grammar School.  Travelling to the United Kingdom, he enlisted in the Royal Naval Air Service in June 1916.  Accepted for flight training, he completed his instruction in December and joined No. 1 (Naval) Squadron RNAS on the Western Front in January 1917, flying Sopwith Triplanes.  He went on to score seventeen aerial victories on this type of machine throughout the year, becoming both the youngest Australian flying ace of the First World War and No. 1 (Naval) Squadron's highest-scoring ace on the Triplane.  The unit re-equipped with the Sopwith Camel late in 1917, with Minifie going on to achieve a further four victories on the aircraft, raising his final tally to a score of twenty-one aircraft shot down. Wing Commander Edwin Swale {'1': ", '2': ", '3': ", '4': "} (28 June 1899 – 19 July 1978) was an English First World War flying ace credited with 17 aerial victories.  His victory list is notable because he scored 14 of his 17 wins against the premier German fighter of the war, the Fokker D.VII, and became the leading Sopwith Camel ace of No. 210 Squadron RAF. Captain George Edwin Thomson DSO MC (19 September 1897 – 23 May 1918) was a Scottish World War I flying ace credited with 21 aerial victories.  He was the second ranking ace of his squadron, and one of the leading Sopwith Camel aces. This is a list of fighter aces in World War II from Germany.  A flying ace or fighter ace is a military aviator credited with shooting down five or more enemy aircraft during aerial combat.  German day and night fighter pilots claimed roughly 70,000 aerial victories during World War II, 25,000 over British or American and 45,000 over Russian flown aircraft.  103 German fighter pilots shot down more than 100 enemy aircraft for a total of roughly 15,400 aerial victories.  Roughly a further 360 pilots claimed between 40 and 100 aerial victories for round about 21,000 victories.  Another 500 fighter pilots claimed between 20 and 40 victories for a total of 15,000 victories.  It is relatively certain that 2,500 German fighter pilots attained ace status, having achieved at least 5 aerial victories.  These achievements were honored with 453 German day and "Zerstörer" (destroyer) pilots having received the Knight's Cross of the Iron Cross.  85 night fighter pilots, including 14 crew members, were awarded the Knight's Cross of the Iron Cross. Captain Noel William Ward Webb {'1': ", '2': ", '3': ", '4': "} (12 December 1896 – 16 August 1917) was a British World War I flying ace credited with fourteen aerial victories.  He was the first pilot to use the Sopwith Camel to claim an enemy aircraft.  He also claimed the life of German ace "Leutnant" Otto Brauneck for his ninth victory. The Sopwith Camel was a British First World War single-seat biplane fighter aircraft introduced on the Western Front in 1917.  It was developed by the Sopwith Aviation Company as a successor to the earlier Sopwith Pup and became one of the most iconic fighter aircraft of the First World War. Lieutenant Thomas Montagu Harries was a Scottish World War I flying ace credited with 11 aerial victories.  He was the second scoring ace using the Sopwith 1½ Strutter; he then also became an ace on the Royal Aircraft Factory SE.5a. Captain Konstantin Konstantinovich Vakulovsky (born 28 October 1894, died Summer 1918) was a World War I flying ace credited with six aerial victories.  A major general's son, he volunteered for aviation duty on 8 August 1914, six days after graduating from university.  He taught himself to fly, and became one of Russia's first military pilots on 13 June 1915.  After escaping the fall of the Novogeorgievsk Fortress in a hazardous flight, Vakylovsky flew reconnaissance missions, some through heavy ground fire.  Given command of the newly formed First Fighter Detachment, he became a flying ace credited with six aerial victories.  He died in a flying accident during Summer 1918.
