Josef Mai was born inOttorowo,Province of Posen. His original military service began on 3 October 1907 with the 10th Lancers. When World War I began Mai was part of the offensive aimed at the French capital ofParis. He later took part in the fighting aroundWarsaw,Poland. In 1915 he campaigned along theDniester River. He also served at the battles ofVerdun and theSomme.^[3]

Mai joined the German air service in 1915; he trained at the Fokker plant atLeipzig.^[3] He earned his pilot's brevet on 28 July 1916,^[4] and flew reconnaissance aircraft for Kasta 29. He then underwent fighter training and joinedJagdstaffel 5 in March 1917. As aVizefeldwebel, he was one of three non-commissioned pilots (along withFritz Rumey andOtto Koennecke) who flew together so successfully they ended up claiming 40% of the Jasta's victories between them, and making Jasta 5 the third highest scoring unit of the war.^[5] The trio was nicknamed "The Golden Triumvirate".^[6]

Mai scored his first victory on 20 August 1917, flying an Albatros D.V, and downing a Sopwith Camel of No. 70 Squadron. His fifth victory, over aRAF SE.5a, was on 30 November.^[4]

Mai did not score again until 13 January 1918. On 25 April 1918 he forced down British ace LtMaurice Newnham of No. 65 Squadron, for his tenth victory.^[1][4]

By May 1918 Jasta 5 was sharing an airstrip withJagdgeschwader 1, and as the "Flying Circus" re-equipped with newFokker D.VIIs, Mai started flying a cast-offFokker Dr.I triplane. He flew this triplane (Serial No. 139/17) for his next victory, over a pair of aces in a No. 11 SquadronBristol F.2B. Pilot LtHerbert Sellars was killed although Observer Lt.Charles Robson survived and taken prisoner. He claimed three victories with the Triplane.^[1][4]

Mai was prone to paint his planes in a "zebra stripe" pattern, with black and white striping on the fuselage angled to the left viewed from the starboard side.^[7] his theory being the optical illusion would help to throw off an enemy pilot's aim.^[8] Painted on this background was his insignia of a star and crescent. His Albatros and D.VII were known to bear this paint scheme although his Dr.l paint scheme is uncertain.^[9]

On 19 August 1918 he had his most successful day. He attacked twoBristol F.2B fighters from No. 48 Squadron,Royal Air Force. As he hit one Brisfit with incendiary ammunition, the other swerved away from the incoming fire and collided with his wrecked companion. Mai followed up this double kill by downing a 56 Squadron SE.5a later.^[10]

On 3 September he was wounded in action in the left thigh. Nevertheless, he scored again two days later, and added five more victories during September.^[1][4]

Mai's 26th victory was a No. 64 Squadron SE5a on 5 September 1918. On 27 September 1918, the day of his 29th success, Mai was promoted to Leutnant.^[3] His friend Fritz Rumey was also killed in action on that day.^[11][12]

Mai claimed his 30th and last score, aBristol F.2B of 20 Squadron, killing the ace crew of Lt. Nicholson Boulton and 2/Lt. C.H. Chase on 29 September 1918.^[1] 15 had been claimed with the Fokker D.VII, 12 with the Albatros and 3 with the Fokker Dr.I.^{[citation needed]}

Mai was nominated for Germany's highest honor, thePour le Merite, or Blue Max. Before it could be approved the war ended with Germany's loss.^[1][3][4]

Mai is believed to have become a flying instructor for theLuftwaffe during World War II.^[2] He died at the age of 94 in January 1982.^[1]
