As German casualties escalated with the combination of Operation Bagration and the Lvov-Sandomierz Operation in the east, and Operation Cobra in the west, members of the Hitlerjugend were recruited at ever younger ages. By 1945, the Volkssturm was commonly drafting 12-year-old Hitler Youth members into its ranks. During the Battle of Berlin, Axmann's Hitler Youth formed a major part of the last line of German defense, and were reportedly among the fiercest fighters.
