Whakaotihia te rerenga e whai ake nei: I te 1 o Oketopa 1942, i whakatairangahia a Neidholdt ki te rangatira nui me te whakatu i te rangatira o te 369th (Croatian) Division Infantry, he roopu legionary i hangaia e nga kaihauturu mai i te Independent State of Croatia i raro i nga kaihauturu Tiamana, i noho ki Yugoslavia. I tiimata te wehenga i Stockerau, Austria me nga mea i ora i te 369th Croatian Reinforced Infantry Regiment me nga kaitautoko hou mai i Croatia, i whakawhiwhia ki te ingoa ingoa "Te Wahanga o te rewera", hei whakanui i te 42nd Home Guard Infantry Division o te Pakanga Tuatahi o te Ao Austro-Hungarian Army. I tohatohahia te wehenga ki nga Balkans ki nga kaitautoko o Yugoslavia i te timatanga o te 1943 kaua ki te Runga rawhiti i te timatanga o te whakaaro. I raro i te whakahau a Fritz Neidholdt i uru te wehenga ki te Case White (e mohiotia ana ko te wha o nga Axis Offensive) i te raki o Bosnia, i reira, kaore i te mohio ki te pakanga guerilla, i rongonui mo tona tino nanakia. Katahi ka whai wāhi te wehenga ki
Case Black i te raki o Montenegro me te tonga o Bosnia, i reira i kii ai te maha o nga tupapaku o nga waahanga katoa i whakaekea.
