Left at Montgomery, it would have compelled the enemy to operate from a distant base of supplies, necessitating his keeping open lines of communication eight hundred miles long, while it would have liberated to be used as occasion demanded, a magnificent army which was constantly required for the defense of Richmond. Located as that place is, within little more than one hundred miles of the enemy's base, upon a river which permitted the ascent of formidable war crafts and within a short distance of a strong fortress on a fine harbor, it was a constant invitation for aggressions which required all of the energies and most of the resources of the South to meet and defend. When in May the president reached Richmond, its defense was already demanding attention. The states had sent forward troops to the aid of Virginia and these were divided into three armies. One of these was posted at Norfolk. Another, under General Joseph E. Johnston, guarded the approach to the Shenandoah Valley, and the third, under General Beauregard, covered the direct approach to the capital from near Manassas. The day the Federal army moved forward to the invasion of the South, Mr. Davis was advised of the fact by one of his secret agents in Washington, and he wired Johnston to abandon Harper's Ferry and effect a junction with Beauregard--an order executed with the celerity and effectiveness which could not have been surpassed by the seasoned troops of a veteran army. But a difficulty now arose. Johnston and Beauregard were commanding separate armies, and in the face of impending battle it was certainly necessary to know who exercised supreme command. [Illustration: Edward Ruffin, who Fired the First Gun at Sumter] Under the law of Congress, it was doubtful if either exercised those functions, Johnston therefore wired an inquiry and received from Mr. Davis only the reply that he was general in the Confederate army. However, the anomalous situation and perhaps another motive, which will be hereafter noticed, induced the president to hasten forward, so as to be himself present upon the field of battle. When he reached Johnston's headquarters, the hard-fought day was closing, the storm of battle was dying away to the westward and General McDowell's army, routed at every point, was retreating in wild disorder toward Washington.
