Battle of Fort Titus: In August 1856 Camp Sacket, a U.S. Army post, was about a mile away from Fort Titus.  Fort Saunders, some distance south of Fort Titus, was destroyed by free-state partisans on August 15, 1856.  Fort Titus was attacked the next day.  This was the Battle of Fort Titus.  About 400 free-staters under the command of Samuel Walker attacked Fort Titus.  Titus had a force of at least twenty-one men, including thirteen German stonemasons from nearby Lecompton, Kansas, with him.  The attack was launched before a brass cannon had arrived on the site.  This attempt was unsuccessful and the leader of this first attack was killed.  Apparently some of the men from this attack placed themselves between Lecompton and the Army troops, so no messages could be sent between Wilson Shannon, the governor, and the troops.
