Anderson was known for his brutality towards Union soldiers, who were called Jayhawkers, and pro-Union civilians in Missouri and Kansas. Anderson participated in Quantrill's raid on Lawrence, Kansas on August 21, 1863. An estimated 200 civilian men and boys were reported to have been killed and many homes and buildings in Lawrence were burned to the ground. On October 26, 1864 Anderson was killed after he and his men were lured into an ambush near the hamlet of Albany, which is now part of Orrick, in Ray County, Missouri. The ambush was carried out by a group of militiamen lead by Colonel Samuel P. Cox.
