Over the rest of November 1939, the "Luftwaffe" reorganized its fighter units on the "Westwall" in preparation for the offensives of the next year. As part of this, I./JG 52 was transferred to on 21 November and was placed under the control of "Luftflotte" 3 along with the rest of JG 52. That same day, Hptm. Klein-Ellguth and his wingman "Leutnant" Christoph Geller were shot down by French fighters. Both survived, but Klein-Ellguth was too severely injured to return to service. JG 52 suffered its first fatality on 22 November when "Unteroffizier" Hans-Joachim Hellwig's plane suddenly went into a steep dive and crashed behind French lines while on a high-altitude patrol. Harsh winter weather brought aerial action to an end for the rest of 1939.
