The Luftwaffe also reacted with a massed response against the airborne invasion of the Netherlands. On the afternoon of 18 September, German fighters attacked a large re-supply effort of Arnhem by Eighth Air Force B-24 bombers. The 357th intercepted a force of 60 Bf 109s near Maastricht, claiming 26 destroyed.The next afternoon the Allies used over 600 transports for airlift in marginal weather conditions, some of which were attacked by numerous German fighters, including Bf 109s of Jadgeschwaders (fighter wings) 11 and 26. The 357th "bounced" the interceptors as they left the battlefield northeast of Arnhem, shooting down 25 (although five were not credited until after the war when repatriated POWs were debriefed). Against their 51 claims, the 357th lost seven Mustangs, with three pilots killed and three captured.
