The convention reassembled in July, 1861, and, by action subject to disapproval or affirmance of the popular vote, deposed the governor, lieutenant-governor, secretary of state, and legislature, and appointed a new executive. This action was approved by a vote of the people. Jackson, assuming to be an ambulatory government as he chased about with forces alternately advancing and fleeing, undertook, by his separate act, to detach Missouri from the Union and annex it to the Confederacy. This clash of action stimulated and intensified a real division of feeling, which existed in every county. A sputtering warfare broke out all over the State. Armed predatory parties, rebel and national, calling themselves squadrons, battalions, regiments, springing up as if from the ground, whirled into conflict and vanished. When a band of men without uniform, wearing their ordinary dress and carrying their own arms, dispersed over the country, the separate members could not be distinguished from other farmers or villagers; and a train, being merely a collection of country wagons, if scattered among the stables and barn-yards of the adjoining territory, wholly disappeared. But all through this eruptive discord flowed a continuous stream of more regular contests, which constitute the connected beginning of the military operations of the Mississippi Valley. Under countenance of Governor Jackson's proclamation, General D.M. Frost organized a force and established Camp Jackson, near St. Louis, the site being now covered by a well-built portion of the city. Jackson had refused to call out troops in response to President Lincoln's requisition, but Frank P. Blair had promptly raised one regiment and stimulated the formation of four others in St. Louis. On May 10, 1861, Captain Nathaniel Lyon, of the regular army, who commanded at the arsenal at St. Louis, and had there a garrison of several hundred regulars, marched with Colonel Blair and the volunteers and a battery to Camp Jackson, surrounded it, and demanded a surrender. Resistance was useless. General Frost surrendered his men and stores, including twenty cannon. St. Louis, and with it Missouri, was thus preserved. Lyon was made brigadier-general of volunteers.
