In Missouri, a constitutional convention was approved and delegates elected by voters. The convention rejected secession 89–1 on March 19, 1861. The governor maneuvered to take control of the St. Louis Arsenal and restrict Federal movements. This led to confrontation, and in June Federal forces drove him and the General Assembly from Jefferson City. The executive committee of the constitutional convention called the members together in July. The convention declared the state offices vacant, and appointed a Unionist interim state government. The exiled governor called a rump session of the former General Assembly together in Neosho and, on October 31, 1861, passed an ordinance of secession. It is still a matter of debate as to whether a quorum existed for this vote. The Confederate state government was unable to control very much the Missouri territory. It had its capital first at Neosho, then at Cassville, before being driven out of the state. For the remainder of the war, it operated as a government in exile at Marshall, Texas.
