Colonel Williamson and his regiment spent the fall of 1862 on garrison duty at Helena, Arkansas. In December Williamson was part of William T. Sherman’s force which attacked the Confederate forces at the battle of Chickasaw Bluffs. Williamson was again wounded and for his services here was eventually awarded the Medal of Honor in 1895.
