GUERRILLA BANDS IN MISSOURI.

In consequence of the disorganized condition of society in this State, bands of armed rebels took occasion to commit depredations upon the loyal citizens. Skirmishes became frequent, terror took the place of security, and distrust that of confidence. Men once high in public opinion and the councils of the nation became leaders in revolt, and encouraged by their example, the rabble threw off all restraint, and boldly became banditti.

Brigadier-General Pope was assigned command in northern Missouri, and from his headquarters at St. Charles, issued a proclamation, assuring loyal citizens of protection, and threatening disorganizers and secessionists with severe punishment. The State Convention assembled on the 22d of July, at Jefferson City, and passed an ordinance on the 23d by a vote of sixty-five to twenty-one, declaring the office of President of their body, held by General Sterling Price, to be vacant, and elected General Robert Wilson, a firm Union man, in his place. A committee of seven—one from each Congressional district, was appointed to report what action was necessary for the State to take in the crisis, and prepare an address to the people. The report was made, Union in all its bearings, and the Convention adjourned.

Major-General Fremont arrived at St. Louis on Sunday the 25th, and assumed military command.

The month of July was prolific in proclamations from the commanders of the rebel forces as well as of the Federal troops. On the 30th of July, rebel regiments from Tennessee, Mississippi and Kentucky, occupied New Madrid, on the Mississippi river, in the southern extremity of the State, and fortified it, and General Gideon J. Pillow issued a manifesto, in which he called upon the men of Missouri to enter his ranks. On the 1st of August, Jefferson Thompson, not to be outdone in the declamatory department, also issued a fiery proclamation.

Depredations had become so numerous and troublesome on the line of the Hannibal and St. Joseph’s railroad, that General Pope appointed General S. A. Hurlbut to guard it, and divided it into sections, notifying the people that all who had property and interests at stake, would be expected to take an active part in their own protection and security. Citizens were appointed district superintendents.

The Address of the State Convention was published on the 31st of the month, and presented the question before the people in a masterly and able manner. The rebel Lieutenant-Governor, Thomas C. Reynolds, found refuge under the protection of General Pillow, at New Madrid, and on the same day, in the absence of Governor Jackson, issued a treasonable proclamation to the people of the State.

While these events were transpiring in other parts of the State, General Lyon had concentrated his forces at Springfield. Although he had perfect confidence in the bravery and discipline of his troops, he yet felt his inability to cope successfully with the superior numbers that he was warned were marching against him, and appealed to General Fremont to reinforce him. This General Fremont declined to do, alleging as a reason that his best regiments had been withdrawn to Washington and Cairo—to important points in the vicinity of St. Louis and the district under General Pope, that required to be guarded; and General Lyon and his little handful of brave men were left to meet, as best they might, the fast accumulating forces of the enemy who were bent on their destruction.
