Lead: For 400 years, service men and women have fought to carve out and defend freedom and the civilization we know as America. This series on A Moment in Time is devoted to the memory of those warriors, whose devotion gave, in the words of Lincoln at Gettysburg, the last full measure. Intro: A Moment In Time with Dan Roberts. Content: George Armstrong Custer, leading the Seventh United States Cavalry Regiment, was participating in a three-army campaign. They were sent by General Philip Sheridan to discipline several warlike Indian tribes who, by the spring of 1876, had drifted off their reservations into the valley of the Little Bighorn River in southern Montana. Custer's regiment was part of the army led by General Alfred Terry that had left Fort Abraham Lincoln on the Missouri River in June. The object of the three armies was to converge, find the wandering Indians, punish them and drag them chastened back to the reservation. Loading... Taking too long?
