I te 9 o Paenga-whāwhā 1944, i tohua a "Oberleutnant" (Tumuaki Tuatahi) Lang hei "Staffelkapitän" o te 9./JG 54 (9th Squadron of the 54th Fighter Wing) e mahi ana i te Defence of the Reich i te Western Front
He aha? I riro ia hei kaiwhiwhi 448 o te Knight's Cross of the Iron Cross with Oak Leaves () i te 11 Paenga-whawha 1944 i muri i nga wikitoria rererangi 144, i kii katoa i te Raki o te Rawhiti. Ko te whakaaturanga i mahia e Adolf Hitler i te Berghof, te kaainga o Hitler i Obersalzberg o nga Bavarian Alps, i te 5 o Mei 1944. I tae atu hoki ki te huihuinga ko Anton Hafner, Otto Kittel, Günther Schack, Alfred Grislawski, Erich Rudorffer, Martin Möbus, Wilhelm Herget, Hans-Karl Stepp, Rudolf Schoenert, Günther Radusch, Otto Pollmann me Fritz Breithaupt, i riro katoa i a raatau nga Oak Leaves i tenei ra.
