It was ascertained that, a few days before the publication of Price's proclamation, Governor Jackson was in consultation with an agent of the Rebel Government, who promised twenty-five thousand men, and arms and ammunition for fifty thousand more, if the State were fairly and unequivocally out of the Union. He had also conferred with an agent from the Indian Nation, with a view to putting several thousand Indians into the field on the side of the Rebels. General Lyon wanted an "overt act" on the part of the Rebels, before commencing actual hostilities. Price's proclamation was the thing desired.
The troops in and around St. Louis were drilled as thoroughly as possible. Every day added to their effectiveness. Recruiting was pushed, trade with the interior was suspended, and boats passing down the river were made subject to stoppage and search at the arsenal. Every thing was assuming a warlike appearance. The Government was very tardy in supplying General Lyon's wants. In many cases it did not authorize him to do what was needed. Much of the money for outfitting the troops for the field was voluntarily contributed in the Eastern cities, or by patriotic men in St. Louis. In several things, General Lyon acted upon his own responsibility, under the advice and co-operation of Colonel Blair.
On the 9th of June, Governor Jackson and General Price asked General Lyon to give them a safeguard to visit St. Louis. They wished to confer with General Lyon and Colonel Blair, upon the best means of bringing peace to the State and making an end of hostilities. The safeguard was granted, and, on the 11th of June, Jackson and Price reached St. Louis, and signified their readiness for the proposed conference. The meeting took place at the Planters' House, Governor Jackson declining to trust himself inside the walls of the arsenal, where General Lyon had invited him to be his guest. The interview began with many professions of goodwill on the part of Governor Jackson, and the assurance of his earnest desire for peace. He promised to disband the State troops, if General Lyon would first remove all United States troops from the limits of Missouri, and agree not to bring them back under any consideration. Of course, this proposition could not be entertained. A conversation then took place between General Lyon and General Price, but all to no purpose. Price and Jackson would do nothing, unless the United States troops were first sent out of Missouri. Lyon and Blair would not consent to any thing of the kind, and so the conference ended.
Jackson and Price left St. Louis on a special train for Jefferson City, on the afternoon of the 11th. On the way up the road, they set fire to the bridges over the Gasconade and Osage Rivers, the former thirty-five miles from Jefferson City, and ninety from St. Louis, and the latter within nine miles of Jefferson City. If the conduct of these men had been neutral up to that time, this act made an end of their neutrality.
General Lyon left the conference fully satisfied there was no longer any reason for hesitation. The course he should pursue was plain before him.
Early in the forenoon of the 12th, he learned of the destruction of the bridges over the Gasconade and Osage Rivers. He immediately ordered a force to proceed up the road, and protect as much of it as possible from further damage. Within four hours of the reception of the order to move, the troops were on their way. On the next day, three steamers, with about two thousand men, left St. Louis for Jefferson City. General Lyon knew the importance of time, and was determined to give Governor Jackson very little opportunity for preparation.
My first experience of a military campaign was on the expedition up the Missouri. I had seen something of Indian troubles on the Plains, in which white men were concerned, but I had never witnessed civilized warfare where white men fought against white men. A residence of several weeks in St. Louis had somewhat familiarized me with the appearance of troops at the arsenal and at the various camps in the city, but the preparations to take the field were full of novelty.
I was on the boat which carried the First Missouri Infantry, and which General Lyon had selected for his head-quarters. The young officers were full of enthusiasm, and eagerly anticipating their first encounter with the Rebel battalions. Colonel Blair was less demonstrative than the officers of his regiment, but was evidently much elated at the prospect of doing something aggressive. General Lyon was in the cabin, quiet, reserved, and thoughtful. With Colonel Blair he conversed long and freely. Few others approached him. Outside the cabin the soldiers were ardently discussing the coming campaign, and wishing an early opportunity for winning glory in battle.
To one who travels for the first time by steamboat from St. Louis in a northerly direction, a curious picture is presented. The water in the Mississippi above the mouth of the Missouri is quite clear and transparent. That from the Missouri is of a dirty yellow color, derived from the large quantity of earthy matter which it holds in solution. For several miles below the junction of the streams, the two currents remain separated, the line between them being plainly perceptible. The pilots usually endeavor to keep on the dividing line, so that one can look from the opposite sides of a boat and imagine himself sailing upon two rivers of different character at the same moment.
Sometimes this distinctive line continues for fifteen or twenty miles, but usually less than ten. A soldier wittily remarked, that the water from the Upper Mississippi derived its transparency from the free States, from whence it came, while the Missouri, emerging from a slave State, was, consequently, of a repulsive hue. As Missouri is now a free State, the soldier's remark is not applicable.
