Sam Houston Anderson - 1861 The 10th Calvary traveled back up North from Vicksburg by rail to the town of Altoona, Penn., then rode their horses the ramainder of the way to join the Calvary forces under the command of Major General A. Pleasanton, the commanding officer of all the Union Calvary, at the battle of Gettysburg. For all 3 days of the Gettysburg battles, Sam was a messanger. The 10th Calvary fought on the Union right flank the first day, and on the left flank the next two days. After the battles ended, the Calvary was moved against General Lee's army of Northern Virginia, but they were stopped at Harper's Ferry and remained there in garrison for the rest of the summer for rest and recuperation before another battle.

In August of 1863, orders came that the 10th Calvary was to move to Northern Tennessee and to take the city of Knoxville and the surrounding area. The Rebel forces were so small they had no chance of winning, so they left. Union forces occupied Knoxville on September 2, 1863. Rebel forces were still in the area, so the Union Army went after them. Sam was in three battles near Knoxville. The first battle was in Telford on September 8, 1863, the second was 15 days later on September 23rd at Bloutsville, and the third was Bulls Gap on October 10, 1863. All three battles were Union victories.

After Bulls Gap, Sam and the 10th Cavary was sent to Chattanooga, Tennesse to be in the Battle Above the Clouds at Lookout Mountain, and also at Missionary Ridge. It was either here or when they moved back to Knoxville that Sam was badly wounded. All Sams records say he was sent home for 6 months due to illness, but all his children say it was a wound. He was cut on his left arm above the elbow and across his chest. Sam spent 6 months at his parents home while his wounds healed. Sam returned to the 10th Tennessee Calvary on June 1, 1864.
