in mid-april 1861, jackson wrote to confederate president jefferson davis, asking for heavy artillery to breach the walls of the arsenal. his letter was carried by militia officers colton green and basil wilson duke. around may 1, jackson called out part of the missouri volunteer militia for "maneuvers" near st. louis, under the command of brigadier general daniel m. frost. the mvm set up "camp jackson", about northwest of the arsenal. the campsite was located at lindell's grove (then outside the city of st. louis, and today part of the campus of st. louis university on lindell boulevard).
