He claimed his first shootdown of an enemy aircraft when he shot down a Bf 109 the next day, while he and his wingman were on a reconnaissance mission, and were jumped by five enemy fighters.

During the first weeks of the war, Pokryshkin began to see very clearly how outdated the Soviet combat doctrine was, and started slowly drafting his own ideas in his meticulous notebooks. He carefully recorded all details of all air engagements he and all his friends were involved in, and came up with detailed analysis of each.

He would later say "one who hasn't fought in 1941–1942 has not truly tasted war".
