William Anderson (1840 – October 26, 1864), known as "Bloody Bill" Anderson, was one of the deadliest pro-Confederate guerrilla leaders of the American Civil War, leading a band of volunteer partisans who targeted Union loyalists and federal soldiers in Missouri and Kansas. After his father was killed by a Union loyalist judge during the war, Anderson killed the judge and fled to Missouri where he robbed travelers and killed several Union soldiers. In 1863 he took a leading role in the Lawrence massacre and later participated in the Battle of Baxter Springs. By 1864 Anderson was the leader of a group of raiders in Missouri. In September 1864, he led a raid on the town of Centralia, where his men captured a passenger train; they executed 24 unarmed Union soldiers in the Centralia Massacre. Later that day they killed more than a hundred Union militiamen in an ambush. Anderson died in battle a month later. (Full article...)
