Whakaotihia te rerenga e whai ake nei: I whakangungu a Grant i nga hoia a te Uniana, a, i whakatairangahia ia ki te Koronela i te Pipiri 1861. Ko te Maj. Gen. John C. Frémont, i kite i a Grant he "aroha rino" ki te wikitoria, i whakatuhia a Grant hei rangatira mo te Rohe o Cairo. I rongonui a Grant puta noa i te motu i muri i tana hopu i a Fort Donelson i te Hui-tanguru 1862 a i whakatairangahia ia ki a Major General e te Perehitini a Aperahama Lincoln. I muri i te raupapa o ngā pakanga whakatau engari utu nui me wikitoria i
Shiloh, Vicksburg, me Chattanooga, i whakatairangahia a Grant ki te Lieutenant General e te Perehitini Lincoln i te tau 1864 ka whakawhiwhia ki nga ope taua katoa. I haere a Grant ki te patu i a Robert E. Lee i muri i tetahi atu raupapa whawhai utu nui i te Whakatairanga o te Whenua, Petersburg, me Appomattox. Whai muri i te Pakanga Taketake, i whakawhiwhia a Grant ki tana whakatairanga whakamutunga o te General of the Armed Forces i te tau 1866 ka mahi tae noa ki te 1869. Ko te rongonui o Grant hei rangatira whawhai a te Uniana i taea ai e ia te kowhiri i nga wa e rua hei Perehitini 18 o te United States.
