1861 May 12th

May 12 1861 Sunday

Maryland. Troops under Massachusetts State Brigadier-General Benjamin Franklin Butler restored Union control in Baltimore over armed pro-secessionist groups.

Missouri. The Missouri General Assembly created the Missouri State Guard to defend the state from attacks from perceived enemies, either from the North or South. The governor appointed Sterling Price as Major-General of State Militia, and specifically of the Missouri State Guard. Fearing Missouri’s drift towards the Confederacy, Union Brigadier-General William Selby Harney drew up a truce with Price which affirmed Missouri’s neutrality in the impending conflict. Governor Claiborne Fox Jackson declared his support for the Union.

Harney’s action was considered to be too favourable to the secessionist cause.  Captain Nathaniel Lyon, who had been leading the pro-Union resistance, was promoted Brigadier-General of Missouri Militia to provide a pro-Union counter-balance. President Abraham Lincoln made a specific request for Missouri troops to be recruited into Union service, which Governor Jackson refused.

South Carolina. USS Niagara, Captain William Wister McKean, captured the blockade-runner General Parkhill, en route from Liverpool to Charleston.
