Alonzo William Slayback
Birth: Jul. 4, 1838
Marion County
Missouri, USA
Death: Oct. 13, 1882
Saint Louis
St. Louis County
Missouri, USA

Colonel Alonzo Slayback was a teacher, lawyer, and Confederate Soldier. Served under General Sterling Price, General John Marmaduke, formed The Slayback Lancers. He married his childhood sweetheart, Alice Amelia Waddell, daughter of William B. Waddell, who was one of the 3 Pony Express founders/operators, and member of the firm Russell, Majors, & Waddell. Alonzo Slayback is mentioned many times in the book written by John Newman Edwards, Shelby and his Men. Slayback went with General Joseph Shelby to Mexico after the surrender. Wrote a poem The Burial of Shelby's Flag. Slayback eventually setup a law practice in St. Louis, Missouri. There he had an ongoing feud with the editor of the St. Louis Post-Dispatch John Cockerill, (who was a Union Army veteran). Slayback and fellow attorney, William Clopton, stormed into Cockerill's office with the intention of slapping the editor and demanding an apology. Cockerill picked up a revolver and shot Slayback in the heart, stating later he had acted in self defense. In spite of the witness William Clopton, the grand jury refused to indict Cockerill. Decades later (July 1, 1920), the truth concerning the pistol found on Slayback's body was finally disclosed by an ex-Post- Dispatch employee that was near death.  (bio by: Bill Walker)
