On Wednesday, May 8, 1861, the guns Jefferson Davis sent to Missouri finally arrived -- too late to do any good.
Missouri Governor Claiborne Jackson was trying to take his state out of the Union. He had his eye on capturing the St. Louis Arsenal for the Confederate cause as well, and had hatched a plot with Jefferson Davis. Jackson would assemble the militia for drill near the arsenal; Davis would send artillery pieces to help them capture it. The guns arrived too late. Most of arms the Confederacy coveted had already been removed.
