Being left in the undisputed occupancy of the seat of government, the governor, lieutenant-governor, and legislature gave themselves up to the enactment of flagrant and undisguised measures of hostility to the federal government. Commissioners from States that had renounced the Constitution, and withdrawn, as they claimed, from the Union, arrived at Jefferson City as apostles of treason. They were received as distinguished and honorable ambassadors. A joint session of the legislature was called to hear their communications. The lieutenant-governor, Reynolds, being the presiding officer of the joint session, required that the members should rise when these traitors entered, and receive them standing and uncovered. The commissioners were allowed to harangue the representatives of Missouri, by the hour, in unmeasured abuse of the federal government, in open rejoicings over its supposed dissolution, and in urgent appeals to the people of Missouri to join the rebel States in their consummated treason. Noisy demonstrations of applause greeted these commissioners; and legislators, and the governor himself, in a public speech in front of the executive mansion, pledged them that Missouri would shortly be found ranged on the side of seceded States. The treason of the governor and legislature did not stop with these manifestations. They proceeded to acts of legislation, preparatory to the employment of force, after the manner of their 'Southern bretheren.' First, it was necessary to get control of the city of St. Louis. The Republican party held the government of the city, mayor, council, and police forcea formidable Union organization. The legislature passed a bill repealing that part of the city charter that, gave to the mayor the appointment of the police, and constituting a board of police commissioners, to be appointed by the governor, who should exercise that power. He named men that suited his purposes. The Union police were discharged, and their places filled by secessionists. Next, the State militia was to be organized in the interests of rebellion, and a law was passed to accomplish that end. The State was set off into divisions; military camps were to be established in each; all able-bodied men between the ages of eighteen and fifty were liable to be called into camp and drilled a given number of days in the year; and, when summoned to duty, instead of taking the usual oath to support the Constitution of the United States, they were required only to be sworn 'to obey the orders of the governor of the State of Missouri.' These camps were styled camps of instruction. One of them was established at St. Louis, within the corporate limits of the city, about two miles west of the court-house, on a commanding eminence.
Thus the lines began to be drawn closely around the Unionists of St. Louis. The State convention had adjourned, and its members had gone home, having done but little to re-assure the loyalists. They had, indeed, passed an ordinance declaring that Missouri would adhere to the Union; but the majority of the members had betrayed such hesitancy and indecision, such a lack of stomach to grapple with the rude issues of the rebellion, that their action passed almost without moral effect. Their ordinance was treated with contempt by the secessionists, and nearly lost sight of by the people; so thoroughly were all classes lashed into excitement by the storm of revolution now blackening the whole Southern Hemisphere.
The friends of the Union could look to but one quarter for aid, that was Washington, where a new administration had so recently been installed, amid difficulties that seemed to have paralyzed its power. The government had been defied by the rebellion at every point; its ships driven by hostile guns from Southern ports; its treasures seized; its arsenals occupied, and its abundant arms and munitions appropriated. Nowhere had the federal arm resented insult and robbery with a blow. This had not been the fault of the government that was inaugurated on the fourth of March. It was the fruit of the official treason of the preceding administration, that had completely disarmed the government, and filled the new executive councils with confusion, by the numberless knaves it had placed in all departments of the public service, whose daily desertions of duty rendered the prompt and honest execution of the laws impossible. But the fact was indisputable; and how could St. Louis hope for protection that had nowhere else been afforded? The national government had an arsenal within the city limits. It comprised a considerable area of ground, was surrounded by a high and heavy stone wall, and supplied with valuable arms. But so far from this establishment being a protection to the loyal population, it seemed more likely, judging by what had occurred in other States, that it would serve as a temptation to the secession mob that was evidently gathering head for mischief, and that the desire to take it would precipitate the outbreak. The Unionists felt their danger; the rebels saw their opportunity. Already the latter were boasting that they would in a short time occupy this post, and not a few of the prominent Union citizens of the town were warned by secession leaders that they would soon be set across the Mississippi river, exiles from their homes forever. As an instance of the audacity of the rebel element at this time, and for weeks later, the fact is mentioned that the United States soldiers, who paced before the gates of the arsenal as sentinels on duty, had their beats defined for them by the new secession police, and were forbidden to invade the sacred precincts of the city's highway. The arsenal was unquestionably devoted to capture, and it would have been a prize to the rebels second in value to the Gosport navy-yard. It contained at this time sixty-six thousand stand of small arms, several batteries of light artillery and heavy ordnance, and at least one million dollars' worth of ammunition. It was besides supplied with extensive and valuable machinery for repairing guns, rifling barrels, mounting artillery, and preparing shot and shell. The future, to the Union men of St. Louis, looked gloomy enough; persecution, and, if they resisted, death, seemed imminent; and no voice from abroad reached them, giving them good cheer. But deliverance was nigh at hand.
About the middle of January, Capt. Nathaniel Lyon, of the Second Infantry, U.S.A., arrived in St. Louis with his company; and his rank gave him command of all the troops then at the arsenal and Jefferson Barracks, a post on the river, ten miles below, the department being under the command of Brigadier General Harney. Capt. Lyon had been garrisoning a fort in Kansas. He was known to some of the Union men of St. Louis; and his resolute spirit and devoted patriotism marked him as their leader in this crisis. Frank Blair at once put himself in communication with Capt. Lyon, and advised him fully and minutely as to the political situation. He exposed to him the existence of his volunteer military organization. At his request Capt. Lyon visited and reviewed the regiments; and it was arranged between them that if an outbreak should occur, or any attempt be made to seize the arsenal, Capt. Lyon should receive this volunteer force to his assistance, arm it from the arsenal, and take command for the emergency. It should be known, however, to the greater credit of the Union leaders of St. Louis, that they had already, from private funds, procured about one thousand stand of arms, with which their nightly drills, as heretofore stated, had been conducted. As soon as Capt. Lyon's connection with this organization was suspected, an attempt was made to have him removed, by ordering him to Kansas on the pretext of a court of inquiry; but this attempt was defeated. Thus matters stood for a time, the Union men beginning to be reassured, but still doubtful of the end. After a while, Fort Sumter was opened upon, and fell under its furious bombardment. The torch of war was lit. President Lincoln issued his proclamation for volunteers. Gov. Jackson telegraphed back an insolent and defiant refusal, in which he denounced the 'war waged by the federal government' as 'inhuman and diabolical.' Frank Blair instantly followed this traitorous governor's dispatch by another, addressed to the Secretary of War, asking him to accept and muster into service the volunteer regiments he had been forming. This offer was accepted, and the men presented themselves. But Brig. Gen. Harney, fearing that the arming of these troops would exasperate the secession populace, and bring about a collision with the State militia, refused to permit the men to be mustered into service and armed. This extraordinary decision was immediately telegraphed to the government, and Gen. Harney was relieved, leaving Capt. Lyon in full command. This was the 23d of April. In a week four full regiments were mustered in, and occupied the arsenal. A memorial was prepared and sent to Washington by Frank Blair, now colonel of the first of these regiments, asking for the enrolment of five other regiments of Home Guards. Permission was given, and in another week these regiments also were organized and armed. The conflict was now at hand. Simultaneously with this arming on the part of the government for the protection of the arsenal, the order went forth for the assembling of the State troops in their camps of instruction. On Monday, the 6th of May, the First Brigade of Missouri militia, under Gen. D.M. Frost, was ordered by Gov. Jackson into camp at St. Louis, avowedly for purposes of drill and exercise. At the same time encampments were formed, by order of the governor, in other parts of the State. The governor's adherents in St. Louis intimated that the time for taking the arsenal had arrived, and the indiscreet young men who made up the First Brigade openly declared that they only awaited an order from Gov. Jacksonan order which they evidently had been led to expectto attack the arsenal and possess it, in spite of the feeble opposition they calculated to meet from 'the Dutch' Home Guards enlisted to defend it. A few days previously, an agent of the governor had purchased at St. Louis several hundred kegs of gun-powder, and succeeded, by an adroit stratagem, in shipping it to Jefferson City. The encampment at St. Louis, 'Camp Jackson,' so called from the governor, was laid off by streets, to which were assigned the names 'Rue de Beauregard,' and others similarly significant; and when among the visitors whom curiosity soon began to bring to the camp a 'Black Republican' was discovered by the soldiers,and this epithet was applied to all unconditional Unionists,he was treated with unmistakable coldness, if not positive insult. If additional proof of the hostile designs entertained against the federal authority by this camp were needed, it was furnished on Thursday, the 9th, by the reception within the camp of several pieces of cannon, and several hundred stand of small arms, taken from the federal arsenal at Baton Rouge, Louisiana, which was then in the possession of the rebels. These arms were brought to St. Louis by the steamboat J.C. Swon, the military authorities at Cairo having been deceived by the packages, which were represented to contain marble slabs. On the arrival of the Swon at the St. Louis levee, the arms were taken from her, sent to Camp Jackson, and received there with demonstrations of triumph.
