In regard to the relative strength of the opposing armies, it is believed that General Rosecrans when he first moved against Bragg had double, if not treble, his force. General Burnside, also, had more than double the force of Buckner; and, even when Bragg and Buckner united, Rosecrans's army was very greatly superior in number. Even the eighteen thousand men sent from Virginia, under Longstreet, would not have given the enemy the superiority.
