Alabama. The Alabama State Convention ratified the Confederate Constitution. It also transferred control of the forts, arsenals, and other facilities in the state to the Confederate Government.
Missouri. The population and state of Missouri were broadly neutral in the secession dispute, but Governor Claiborne Fox Jackson was a strong Southern sympathiser, as were many of the state legislators. US Captain Nathaniel Lyon (Company B 2nd US Infantry), suspected that Jackson would attempt to seize the arsenal in St. Louis if the state seceded and knew that he had insufficient force availabe to prevent the seizure. He attempted to strengthen the defences but met resistance from his superior officer Brigadier-General William Selby Harney, commanding the Department of the West. Lyon exploited his friendship and shared abolitionist views with Francis Preston Blair Jr, and was assigned to command the important St Louis Arsenal. Lyon was involved in the St Louis Wide Awakes, a pro-Union paramilitary organisation that he intended to arm and muster into the service of the Federal army to protect the arsenal. After assuming command at the arsenal, Lyon armed the Wide Awakes under the cover of darkness. The excess weapons in the arsenal were removed secretly to Illinois. Lyon discovered a clandestine operation whereby artillery captured at the US arsenal in Baton Rouge was being shipped to the pro-Confederate Missouri State Guard camp in St Louis. Lyon allegedly disguised himself as a farm woman to spy on the State Guard’s camp and claimed to have exposed Governor Jackson’s plot to seize the arsenal for Missouri troops..
