In Missouri, Federal forces arrest 639 pro-secession St Louis militiamen and face city mobs in response

Camp Jackson, on the edge of the city at Lindell's Grove, was the headquarters of the pro-secession militia in St. Louis. Union Captain Nathaniel Lyon, with regular troops and the largely German-speaking volunteers he had recruited captured the camp and the 639 men there under the command of General Daniel M. Frost.  While marching the prisoners into the city, Lyon's men were attacked by pro-southern mobs and when shot at, returned fire, killing around 28 civilians and wounding many more.  (By John Osborne)
