Around May 1 Missouri Governor Claiborne Jackson who had favored the South but had publicly pledged to uphold Missouri neutrality (at least until open hostilities between the Federal Government and the CSA) called out the Missouri Volunteer Militia for "maneuvers" about 4 miles northwest of the arsenal at Lindell's Grove (now the campus of St. Louis University) then outside the city of St. Louis in what has been called "Camp Jackson."
