Tuhia he haere tonu mo tenei whitianga - I whakakorehia a Smith i te whakahau i te marama o Hurae na te mate kino, a ka whakakapihia e Edward OC Ord a muri ake ko Godfrey Weitzel. Ko Charles A. Heckman i whakahau poto i te roopu whai muri i te whara o te Tiamana Ord i te Pakanga o Chaffin's Farm. I noho a John Gibbon hei rangatira mo te wa poto o te ope taua i te marama o Hepetema 1864. I noho te ope ki te raina o nga turanga tata ki te raina matua o te Rōpū, a he nui nga mate i roto i nga pakanga tata ki te ra mo te marama. I whakawatea te ope taua i tana tuunga e te X Corps i te Akuhata 26, a i tukuna te ope taua ki te Bermuda Hundred, ana i muri mai ki te taha raki o te awa o James. I uru tana wehenga tuatahi ki te whakaeke angitu ki Fort Harrison i te Akuhata 29 i te Pakanga o Chaffin's Farm. I whakauruhia hoki te roopu i te Oketopa 27 i te Pakanga Tuarua o Fair Oaks, i whawhai i runga i te whenua kotahi me te pakanga tuatahi
