Following Lee's surrender of the Army of Virginia to Grant on April 9, 1865 at Appomattox, Captain John Bitter of Abiqua Creek, Oregon musters out of the 40th Missouri. A loner, Bitter plans a quick ride home over the Oregon Trail. The good Lord, however, has other plans for him. After a month on the Trail, two gun battles, a bruising fistfight to settle a blood feud, a new wife, and two adopted sons, Bitter tells Rockford, his big, mean, black horse, "This sure complicates the business of getting back to Oregon."Bitter now finds himself the leader of a mixed entourage going west: a black pioneer family earlier wagon trains shunned; an Irish rebel turned galvanized Yankee; a dispossessed Cherokee turned Cheyenne medicine man; the rescued sister of a Bannock chief; a white boy adopted by the Cheyenne; and a scout for the Union Army who is also one of the richest men in Oregon.Bitter's Run is a spirited and adventurous tale. Told in three parts, it portrays the realities and uncertainties of life on the Oregon Trail, of the war-weary men seeking or returning to a homestead in Oregon, and of the courageous women who rode with them.
