Tuhia he tomokanga mo tenei whitianga - I te Pakanga Taiao o Amerika, i mahi a Newbury i te 6th Regiment Kansas Volunteer Cavalry, ka eke ki te taumata o te rangatira tuatahi. I muri mai ka mahi ia i roto i te ope taua o te Cumberland, e whawhai ana mo te Uniana i te Pakanga o Chickamauga me nga pakanga o Missionary Ridge me Lookout Mountain
He aha? Whai muri i te pakanga, i tohua a Newbury hei Kaiawhina Provost Marshal o te Kawanatanga o Kansas. I paahitia ia i te paari i Kansas i te tau 1865 ka mahi ture i reira mo tetahi wa. I mahi ia hei rangatira poari o Iola, Kansas, engari i wehe ia i te 1870 i muri i tana whakatau ki te neke ki te Tai Hauauru, i noho ai ia ki Portland, Oregon, i Akuhata o taua tau.
