text: On 18 June 1916, German flying ace Max Immelmann was killed in combat with F.E.2bs of No. 25 Squadron RFC. The squadron claimed the kill, but the German version of the encounter is either that Immelmann's Fokker Eindecker broke up after his synchroniser gear failed and he shot off his own propeller, or that he was hit by friendly fire from German anti-aircraft guns. In any case, by this time the F.E.2b was at least encountering the German monoplane fighters on more or less even terms and the so-called "Fokker scourge" had ended.
  By autumn 1916, the arrival of more modern German fighters such as the Albatros D.I and Halberstadt D.II meant that even the F.E.2d was outperformed and by April 1917, it had been withdrawn from offensive patrols.  Despite its obsolescence in 1917, the F.E.2 was still well liked by its crews for its strength and good flight characteristics and it still occasionally proved a difficult opponent for even the best German aces. Rittmeister Baron von Richthofen was badly wounded in the head during combat with F.E.2d aircraft in June 1917 – the Red Baron, like most German pilots of the period, classed the F.E.2 as a "Vickers" type, confusing it with the earlier Vickers F.B.5.
