Camp Jackson
What enthusiasm on that gusty Monday morning, the Sixth of May, 1861! Twelfth Street to the north of the Market House is full three hundred feet across, and the militia of the Sovereign State of Missouri is gathering there. Thence by order of her Governor they are to march to Camp Jackson for a week of drill and instruction.

Half a mile nearer the river, on the house of the Minute Men, the strange flag leaps wildly in the wind this day.

On Twelfth Street the sun is shining, drums are beating, and bands are playing, and bright aides dashing hither and thither on spirited chargers. One by one the companies are marching up, and taking place in line; the city companies in natty gray fatigue, the country companies often in their Sunday clothes. But they walk with heads erect and chests out, and the ladies wave their gay parasols and cheer them. Here are the aristocratic St. Louis Grays, Company A; there come the Washington Guards and Washington Blues, and Laclede Guards and Missouri Guards and Davis Guards. Yes, this is Secession Day, this Monday. And the colors are the Stars and Stripes and the Arms of Missouri crossed.
