George Custer

In September 1867, General Custer was charged and court-martialed with “absence without leave from his command,” and “conduct prejudicial to good order and military discipline.” After Custer was appointed lieutenant colonel over the 7th Cavalry, he and his men set off to assist the U.S. Army with the Indian problems in eastern Kansas. Major General Winfield S. Hancock was assigned to head a campaign against the Indians in the spring of 1867, and Custer's 7th Cavalry would be a major part of the campaign. On July 17, 1867, Custer arrived at Fort Wallace to find it under siege by Indians, low supplies of food and ammunition, and soldiers plagued with cholera. Acting entirely on his own, Custer abandoned the fort and traveled to Fort Harker, 225 miles east, to obtain supplies. He arrived at Fort Harker on July 19 and was arrested on the 21st. His court-martial was set for September. Custer was found guilty on five charges and suspended from duty and pay for one year. However, in 1868, General Philip Sheridan faced a new onslaught of Indian attacks, and he called Custer back early to help. This began the last chapter of Custer's life that ended with the Battle of Little Big Horn where he died fighting the most successful group of Indian warriors in United States history.

On the third day of the Battle of Gettysburg, Confederate General Robert E. Lee planned to launch a two prong attack on the Union position.  The Union front will be attacked by Pickett's Charge, while the Confederate cavalry, led by JEB Stuart.

About two miles from the Union line, Stuart's Cavalry was met by Union Cavalry led by George Custer.  After a brief but bloody clash, the Confederate was forced to  retreat.

The 7th Cavalry under Colonel George Custer was stationed in Fort Abe Lincoln in what was then, the Dakota Territory. Today is located on the Missouri River some 13 miles down stream from Bismark, North Dakota.  Colonel George Custer and his wife Libby stayed here from 1873 til his death in 1876.  It was from here that 7th Cavalry departed for the Big Horn.
