Whakaotihia te rerenga e whai ake nei: I hoki a Gibbon ki te whakahau i te 2nd Division i te wa o te General Grant's Overland Campaign i te Mei me te Pipiri o te tau 1864, i kite i nga mahi i nga pakanga o te Wilderness, Spotsylvania Court House, me Cold Harbor. I te Pipiri 7, 1864, i whakatairangahia ia ki te rangatira nui o nga kaitautoko. I te pakanga o te Siege o Petersburg i muri mai (Hune 1864 ki Aperira 1865), i pouri a Gibbon i te kore o ana hoia e whawhai i
Ream's Station i te marama o Akuhata 1864. I whakahau poto ia i te XVIII Corps i mua i tana wehenga mate, engari i te mea he nui rawa te uara o tana ratonga, ka hoki mai ia ki te whakahau i te XXIV Corps i hangaia hou i roto i te Army of the James. I awhina ana ana hoia ki te whakatutuki i te pakaru nui i te Pakanga Tuatoru o Petersburg i te Paenga-whawha 1865, i te hopu i a Fort Gregg, tetahi waahanga o nga parenga o te Confederate. I te pakanga o Appomattox, i awhina ia ki te aukati i te rerenga rerenga a te Rōpū i te Pakanga o Appomattox Courthouse, i hua ai te tuku a Gen. Lee. Ko ia tētahi o ngā kaitohutohu e toru mō te tuku a te Rōpū.
