He was killed on 10 April 1945, when his aircraft rolled into a bomb crater and exploded during an attempted emergency landing at Parchim.

[2] At the time, this Staffel was commanded by Oberleutnant Rudolf Miethig and was part of I. Gruppe (1st group) of JG 52 headed by Hauptmann Helmut Bennemann.

[3] World War II in Europe had begun on Friday 1 September 1939 when German forces invaded Poland.

In February 1943, I. Gruppe was based at Poltava on the Eastern Front and was subordinated to Luftwaffenkommando Don which supported the fighting in the Third Battle of Kharkov.

[5] In preparation for Operation Citadel, I. Gruppe was moved to Bessonovka, a makeshift airfield located approximately 20 kilometers (12 miles) on 4 July.

[6] On 13 July during the Battle of Kursk, Schall, accompanied by his wingman Oberfeldwebel Franz Woidich, claimed an Ilyushin Il-2 ground attack aircraft shot down.

[8] On 11 November 1943, Schall was shot down and wounded by anti-aircraft artillery in his Messerschmitt Bf 109 G-6 (Werknummer 410131—factory number) resulting in a forced landing 3 kilometers (1.9 miles) south of Kerch.

[11] Fighting across Poland, it led to his most prolific period in the war with a number of multiple victories in a day: three on 12 August (74–76), three more on the 24th (79–81).

[16] On 26 August, Schall became a "double ace-in-a-day" for the first time, claiming eleven aerial victories which included six Il-2 ground-attack aircraft.

[20][21] On 7 October, Schall and Feldwebel Helmut Lennartz were scrambled at 13:45 from Hesepe airfield to intercept a heavy bomber formation.

In this encounter, both Schall and Lennartz each claimed a USAAF Consolidated B-24 Liberator bomber shot down, the first aerial victories of Kommando Nowotny.

Galland had already visited Kommando Nowotny several times and was deeply concerned over the high attrition rate and meager success achieved by the Me 262.

After inspecting the two airfields at Achmer and Hesepe, he stayed in the Penterknapp barracks discussing the problems of the past few weeks.

Two Rotten of Me 262 were prepared for take-off, Erich Büttner and Schall at Hesepe, and Nowotny and Günther Wegmann at Achmer.

At first only Schall and Wegmann managed to take off because Büttner had a punctured tire during taxiing and Nowotny's turbines initially refused to start.

[24][25] By the time the Americans returned from their bomb run, Nowotny, his aircraft now serviceable, and Schall took off alone and made contact with the bomber force at an altitude of 10,000 meters (33,000 feet).

Attempting to glide his aircraft to Hesepe, Schall was shot down by Lieutenant James W. Kenney of the 357th Fighter Group.

[33][34] The next day, 374 Boeing B-17 Flying Fortress bombers from the 3d Air Division attacked Carl Zeiss AG, a manufacturer of optical systems, in Jena, and the motor vehicle factories at Zwickau and Plauen.

[35][36][37] On 21 March 1945, the USAAF Eighth Air Force attacked various Luftwaffe airfields in Germany with approximately 1,300 heavy bombers, escorted by 750 fighter aircraft.

[43] On 31 March 1945, the Royal Air Force (RAF) Bomber Command targeted Wilhelmshaven, Bremen and Hamburg.

[45] That day, RAF Bomber Command had targeted Nordhausen with 243 Avro Lancaster bombers while the USAAF Eighth Air Force sent 950 B-17s and B-24s to Luftwaffe airfields at Kaltenkirchen, Parchim, Perleberg, Wesendorf, Faßberg, Hoya, Dedelstorf and Eggebek, as well as the U-boat yards at Finkenwerder and shipyards at Kiel.

He was then killed when his aircraft rolled into a bomb crater, flipped, and exploded during an attempted emergency landing at Parchim Airfield.
