On this day, 85 years ago, on September 15, 1940 (August 14, 1940 in the lunar calendar), a large-scale air war broke out between the British and German air forces. On September 15, 1940, the German army dispatched thousands of aircraft to launch an air strike on London. The 3rd Bombing Aviation Regiment of the German 2nd Air Force was first intercepted by the Spitfire fighters of the British 72nd and 92nd Squadron over Canterbury. The German forces suffered heavy losses in the air battle. At 13:30, a large number of German aircraft once again flocked to the British coast, and hundreds of British fighter jets successively entered into air combat. Fierce air battles broke out everywhere in southeastern England, from the Straits to London. The fighting lasted for a whole day. According to British statistics, the Royal Air Force shot down a total of 176 German aircraft (124 bombers, 52 fighter jets), and the British Air Force lost 25 fighter jets. Due to the heavy losses of the German army, Goering was forced to order that the air strikes on London would be carried out at night starting on October 1. Later, the United Kingdom designated September 15 as the "Great Britain Air War Day". Comment: This war forced Hitler to abandon Britain and turn to the Soviet Union, reversing the entire war in Europe
