Wilhelm Mayer (fighter pilot)

On 29 April 1943, the USAAF flew its largest mission to date, sweeping the Dutch coast from Ostend to Woensdrecht. Led by Major Josef Priller, 6. and 8. Staffel intercepted Republic P-47 Thunderbolt fighters off the coast. During the encounter, Mayer shot down a P-47 fighter from the 56th Fighter Group 30 km (19 mi) north of Ostend.[13] On 13 June, Mayer shot down a P-47 from the 78th Fighter Group 40–50 km (25–31 mi) north-northwest of Dunkirk. That day, the VIII Bomber Command flew a mission to Kiel and Bremen.[14]

He was credited with his first aerial victory over a heavy bomber in Defense of the Reich on 22 June during the Battle of the Ruhr. The claim was made over a B-17 bomber from the 381st Bombardment Group or 384th Bombardment Group as a Herausschuss (separation shot) near Antwerp. A Herausschuss was a severely damaged heavy bomber forced to separate from its combat box which normally was counted as an aerial victory.[15] On 30 July 1943, Mayer was wounded and made a forced landing northeast of Emmerich in his Fw 190 A-5 (Werknummer 57222) following combat with a B-17 bomber.[16] On 3 September, Mayer was credited with another Herausschuss over a B-17 bomber near Melun on its mission to bomb Paris. The B-17 belonged to either the 381st Bombardment Group or the 384th Bombardment Group. Shortly after, he claimed a P-47 from the 56th Fighter Group shot down near Creil. This claim was not confirmed.[17]

On 18 February 1944, the RAF flew Operation Jericho, a low-level bombing raid, on the Amiens Prison in German-occupied France. The objective of the raid was to free French Resistance and political prisoners.[18] The attack force of nineteen de Havilland Mosquito bombers was escorted by eight Hawker Typhoon fighters from No. 174 Squadron. At 11:35, Luftwaffe fighters were scrambled from Grévillers. Following the bomb run by the Mosquitos, the commanding officer of the operation, Group Captain Percy Charles Pickard of the No. 140 Wing, circled the target to assess the result of the operation. Pickard was attacked by Mayer and shot down at 12:05, killing him and his navigator Flight Lieutenant John Alan Broadley.[19][20] Mayer was transferred on 31 March, becoming a flight instructor.[21] During his tour as an instructor, he was awarded the German Cross in Gold (Deutsches Kreuz in Gold) for 15 aerial victories on 16 April.[22] Mayer returned to II. Gruppe in August and was assigned to 5. Staffel.[23]

Mayer claimed his first aerial victory following his tour as an instructor on 18 August during the Battle of the Falaise Pocket. A pocket had been formed around Falaise, Calvados, in which the German Army Group B, with the 7th Army and the Fifth Panzer Army (formerly Panzergruppe West) were encircled by the Western Allies following the Normandy landings on 6 June. Flying multiple missions in support of the encircled German forces, Mayer shot down a North American P-51 Mustang from the No. 315 Polish Fighter Squadron and a P-47 fighter near Beauvais.[24] On 25 August, the day Paris was liberated, the USAAF Ninth Air Force attempted to eliminate the remaining German fighter forces in France. Defending against this attack, Mayer shot down a 354th Fighter Group P-51 near Saint-Quentin.[25][26]

On 17 September 1944, Allied forces launched Operation Market Garden, the operation to secure a bridgehead over the River Rhine.[27] Two days later, II. Jagdkorps dispatched 148 fighters to the combat area. Mayer was credited with shooting down two P-51 fighters near Nijmegen that day, taking his total to 20 aerial victories.[28] On 23 September, the Allies flew resupplies to the combat area around Arnhem. The transport aircraft were protected by 519 fighters from the VIII Fighter Command and 40 Lockheed P-38 Lightning fighters from the Ninth Air Force. German fighters dispatched by Luftflotte Reich never reached the transports. Over Goch, II. Gruppe intercepted a flight P-51 fighters from the 352nd Fighter Group. For the loss of one of their own, II. Gruppe shot down four P-51 fighters, including one by Mayer.[29] On 27 September, Mayer shot down a RCAF No. 412 Squadron Spitfire over the airfield at Kirchhellen. This is last known aerial victory claimed by a pilot of JG 26 to have been fully confirmed by the Ministry of Aviation (Reichsluftfahrtministerium).[30]

On 22 October, the Staffelkapitän (squadron leader) of 8. Staffel, Oberleutnant Karl-Wilhelm Hofmann, was injured in a ground accident. Although he continued flying combat missions, temporarily, command of his 8. Staffel was passed on to Mayer as Staffelführer (acting squadron leader).[31] Mayer claimed his last two aerial victories on 19 November in combat with the RCAF No. 412 Squadron. Spitfires from No. 412 Squadron were attacking a bridge at Veen in the Netherlands when they came under attack by Fw 190s from II. Gruppe. In this encounter, Mayer claimed two Spitfires shot down north of Kirchhellen.[32]

Mayer was killed in action on 4 January 1945. Officially a member of 5. Staffel, Mayer led a flight from 8. Staffel on mission from the airfield at Nordhorn. Shortly after takeoff, the flight came under attack by Spitfires from the RCAF No. 442 Squadron. In this encounter, Mayer was shot down in his Fw 190 D-9 (Werknummer 500052) near Lohnerbruch.[33] Mayer's inseparable friend Heinz-Gerhard Vogt, commander of 5. Staffel, was killed in action ten days later.[34] Posthumously, he was awarded the Knight's Cross of the Iron Cross (Ritterkreuz des Eisernen Kreuzes) on 12 March 1945.[35]

According to Obermaier, Mayer was credited with 27 aerial victories, claimed over the Western Front and in Defense of the Reich, in 124 combat missions.[1] Mathews and Foreman, authors of Luftwaffe Aces: Biographies and Victory Claims, researched the German Federal Archives and found records for 27 aerial victory claims, plus thirteen further unconfirmed claims, all of which were recorded on the Western Front.[36]

Victory claims were logged to a map-reference (PQ = Planquadrat), for example "PQ 05 Ost TE-1". The Luftwaffe grid map (Jägermeldenetz) covered all of Europe, western Russia and North Africa and was composed of rectangles measuring 15 minutes of latitude by 30 minutes of longitude, an area of about 360 square miles (930 km²). These sectors were then subdivided into 36 smaller units to give a location area 3 km × 4 km (1.9 mi × 2.5 mi) in size.[37]
