context: Bär was born on March 21, 1913 in Sommerfeld near Lipsk. In 1935 he entered the Luftwaffe and was trained to fly bombers. After graduating, Bär was instead assigned to become a transport pilot like Junkers Ju 52 / 3m. In early 1939 he completed training as a combat pilot and was placed in Jagdgeschwader (JG) 51. On September 25 of the same year, Bär scored his first aerial victory after shooting down a Curtiss H-75 A-2 from GC I / 4 France. During the German campaign in France in 1940, the score increased by seven more: 3 French and 4 British aircraft. At the Battle of Britain Bär had heavy opponents and several times he had to return to his base carrying a broken and perforated Bers 109 Messerschmitt. On one occasion he even managed to escape from the ambush of 10 British fighter planes that surrounded him! On 2 September 1940 Bär had the experience of "swimming" on the Channel after his plane was shot down and he jumped with a parachute.
