In January 1945, the Luftwaffe attempted one last major air offensive against the Allied Air Forces. Over 950 fighters had been sent west from the Eastern Front for "Operation Bodenplatte". On 1 January, the entire German fighter force in the West, comprising combat aircraft from some eleven "Jagdgeschwader" day fighter wings, took off and attacked 27 Allied airfields in northern France, Belgium and the southern part of the Netherlands in an attempt by the Luftwaffe to cripple Allied air forces in the Low Countries of Europe. It was a last-ditch effort to keep up the momentum of the German forces during the stagnant stage of the Battle of the Bulge ("Unternehmen Wacht am Rhein"). The operation was a pyrrhic success for the "Luftwaffe" as the losses suffered by the German air arm were irreplaceable and over 300 Luftwaffe aircraft were shot down, mostly by Allied anti-aircraft guns. The losses of the Allied Air Forces were replaced within weeks. The operation failed to achieve air superiority, even temporarily, and the German Army continued to be exposed to air attack.
