Tuhia he tomokanga mo tenei whitianga - I te marama o Akuhata 1945, i tohua a Brown hei kaiawhina mo te rangatira o te roopu o te ono o nga hoia i raro i a Walter Krueger. I te mea he rangatira kaimahi mohio ia, i uru ia ki te whakamahere i te Operation Downfall, i whakamaherehia te whakaekenga ki Japan. Heoi anō, ko te Emepara o Hapani
i tukua i te 2 o Hepetema, 1945, ā, i whakakorea te mahi. I whakawhiwhia a Brown ki te Tohu Whetu Parahi mo tana whakauru ki te whakamahere. I a ia e mahi ana i tenei mana, i uru hoki ia ki te Whakahaere o Hapani.
