Whakaotihia te rerenga e whai ake nei: I te Oketopa 1942, i riro ia hei rangatira mo te XI Corps. I ārahi ia i te ope taua i te Pakanga o te Moananui-a-Kiwa, i te whawhai ki New Guinea me
Ko Morotai. Katahi ka whawhai te roopu ki Leyte me Luzon i roto i te pakanga o Piripi, ina koa i te Pakanga o Bataan. I tohua a Hall ki te arahi i te XI Corps ki te takutai i Shibushi Bay i roto i te Operation Downfall, engari i aukatihia tenei e te Surrender o Japan. I te marama o Hepetema 1945, ka tae te ope ki Yokohama mo te mahi tuatahi o Japan. I whakarerea e Hall te whakahau o te ope taua i te Poutu-te-rangi 15, 1946.
