On 26 November 1944, a Me 262A-2a Sturmvogel of III."Gruppe"/KG 51 'Edelweiß' based at Rheine-Hopsten Air Base near Osnabrück was the first confirmed ground-to-air kill of a jet combat aircraft. The Me 262 was shot down by a Bofors gun of B.11 Detachment of 2875 Squadron RAF Regiment at the RAF forward airfield of Helmond, near Eindhoven. Others were lost to ground fire on 17 and 18 December when the same airfield was attacked at intervals by a total of 18 Me 262s and the guns of 2873 and 2875 Squadrons RAF Regiment damaged several, causing at least two to crash within a few miles of the airfield. In February 1945, a B.6 gun detachment of 2809 Squadron RAF Regiment shot down another Me 262 over the airfield of Volkel. The final appearance of 262s over Volkel was in 1945 when yet another fell to 2809's guns.
