During the last week of the war, Johnson's squadron flew patrols over Berlin and Kiel as German resistance crumbled. During a flight over central Germany looking for jet fighters, Johnson's squadron attacked Luftwaffe airfields. On one sortie, his unit strafed and destroyed 11 Bf 109s that were preparing to take off. On another sortie, an enemy transport was sighted, but took evasive action and retreated back to German held territory but Johnson's pilots shot it down. On another occasion, Johnson intercepted a flight of four Fw 190s. The German fighters, however, waggled their wings to signal non-hostile intent and Johnson's unit escorted them to an RAF airfield.
