Whakaotihia te rerenga e whai ake nei: I nga Pakanga mo Chattanooga, i whakahawea a Grant ki te whakamahi i te Ope o te Cumberland i roto i nga pakanga nui, i te wehi kei te iti rawa to ratou wairua i muri i te hinganga i Chickamauga. Engari, i whakamahia e ia ngā hōia o te ope taua o Potomac, e whakapehapeha ana ki to rātau wikitoria o mua ake nei i te Pakanga o Gettysburg, hei tango i
Lookout Mountain me te whakamahere ki te whakamahi i nga hoia mai i te Army o te Tennessee, ko nga toa hou i te Siege o Vicksburg, ki te whakaeke i te taha matau o te Confederate i Missionary Ridge. I whakawhiwhia te ope taua o Cumberland ki te mahi iti ki te hopu i nga poka pupuhi i te turanga o Missionary Ridge. Heoi, i te wa i tutuki ai ta raatau whaainga, e wha nga wehenga (ko tetahi e arahina ana e Philip H. Sheridan) i whakaeke i te pukepuke ka whakaeke i te pokapū Confederate. I te patai a Grant i te riri ko wai i whakahau i aua hoia ki runga i te pukepuke ko Thomas raua ko Gordon Granger, he rangatira o te ope taua, i whakautu kaore raua i mohio. Kātahi ka tāpiri atu a Granger, "Ki te tīmata rātau, e kore e taea e te reinga katoa te whakamutu i a rātau".
