“ This added gall and wormwood to Anderson's already embittered disposition, and from that time until his death he was more brutal than before. It is said that his gang did more killing at Lawrence than any other portion of Quantrill's command, and after the massacre at Baxter Springs he wanted to attack the fort, but Quantrill would not consent. Anderson was killed while on one of his raids, Oct. 27, 1864, and after his death the scalps of two women were found on the headstall of his bridle.
