Captain George Edward Henry McElroy, a leading Irish-born fighter pilot of the Royal Flying Corps and Royal Air Force during World War I, is born at Donnybrook, County Dublin, on May 14, 1893. He is credited with 47 aerial victories.

McElroy enlists promptly at the start of World War I in August 1914, and is shipped out to France two months later. He is serving as a corporal in the Motor Cyclist Section of the Royal Engineers when he is first commissioned as a second lieutenant on May 9, 1915. While serving in the Royal Irish Regiment he is severely affected by mustard gas and is sent home to recuperate. He is in Dublin in April 1916, during the Easter Rising, and is ordered to help quell the insurrection. McElroy refuses to fire upon his fellow Irishmen and is transferred to a southerly garrison away from home.

On June 1, 1916, McElroy relinquishes his commission in the Royal Irish Regiment when awarded a cadetship at the Royal Military Academy, Woolwich, from which he graduates on February 28, 1917, and is commissioned as a second lieutenant in the Royal Garrison Artillery.

McElroy is promptly seconded to the Royal Flying Corps, being trained as a pilot at the Central Flying School at Upavon, and is appointed a flying officer on June 28. On July 27 his commission is backdated to February 9, 1916, and he is promoted to lieutenant on August 9. On August 15 he joins No. 40 Squadron RFC, where he benefits from mentoring by Edward “Mick” Mannock. He originally flies a Nieuport 17, but with no success in battle. By the year’s end McElroy is flying Royal Aircraft Factory S.E.5s and claims his first victory on December 28.

An extremely aggressive dogfighter who ignores often overwhelming odds, McElroy’s score soon grows rapidly. He shoots down two German aircraft in January 1918, and by February 18 has run his string up to eleven. At that point, he is appointed a flight commander with the temporary rank of captain and transferred to No. 24 Squadron RFC. He continues to steadily accrue victories by ones and twos. By March 26, when he is awarded the Military Cross, he is up to 18 “kills.” On April 1, the Army’s Royal Flying Corps (RFC) and the Royal Naval Air Service (RNAS) are merged to form the Royal Air Force, and his squadron becomes No. 24 Squadron RAF. McElroy is injured in a landing accident on April 7 when he brushes a treetop while landing. By then he has run his score to 27. While he is sidelined with his injury, on April 22, he is awarded a bar to his Military Cross. Following his convalescence, McElroy returns to No. 40 Squadron in June, scoring three times, on the 26th, 28th, and 30th. The latter two triumphs are observation balloons. That runs his tally to thirty.

In July, he adds to his score almost daily, a third balloon busting on the 1st, followed by one of the most triumphant months in the history of fighter aviation, adding 17 victims during the month. His run of success is threatened on the 20th by a vibrating engine that entails breaking off an attack on a German two-seater and a rough emergency landing that leaves him with scratches and bruises. There is a farewell luncheon that day for his friend Gwilym Hugh “Noisy” Lewis. Their mutual friend Edward “Mick” Mannock pulls McElroy aside to warn him about the hazards of following a German victim down within range of ground fire.

On July 26, Mannock is killed by ground fire. Ironically, on that same day, “McIrish” McElroy receives the second Bar to his Military Cross. He is one of only ten airmen to receive the second Bar.

McElroy’s continues apparent disregard for his own safety when flying and fighting can have only one end. On July 31, 1918, he reports destroying a Hannoversche Waggonfabrik C for his 47th victory. He then sets out again. He fails to return from this flight and is posted missing. Later it is learned that McElroy has been killed by ground fire. He is 25 years old. McElroy is interred in Plot I.C.1 at the Laventie Military Cemetery in La Gorgue, northern France.

McElroy receives the Distinguished Flying Cross posthumously on August 3, citing his shooting down 35 aeroplanes and three observation balloons. The Bar arrives still later, on September 21, and lauds his low-level attacks. In summary, he shoots down four enemy aircraft in flames and destroys 23 others, one of which he shares with other pilots. He drives down 16 enemy aircraft “out of control” and out of the fight. He also destroys three balloons.
