Marseille continued scoring multiple victories throughout September, including seven on 15 September (nos. 145–151). Between 16 and 25 September, Marseille failed to increase his score due to a fractured arm, sustained in a force landing soon after the 15 September mission. As a result, he had been forbidden to fly by Eduard Neumann. But the same day, Marseille borrowed the Macchi C.202 '96–10' of the Italian ace "Tenente" Emanuele Annoni, from 96a "Squadriglia", 9° "Gruppo", 4° "Stormo", based at Fouka, for a test flight. But the one-off flight ended in a wheels-up landing, when the German ace accidentally switched the engine off, as the throttle control in Italian aircraft was opposite to that of the German aircraft. The event was photographed.
