The first two years of civil strife had closed. The American people, which so far had shown more aptness at learning than skill in waging war, may be said to have passed through its apprenticeship in arms. The broad plan of operations, intelligently but rudely conceived at the outset by the greater spirits among our commanders, began to be more clearly grasped. The political strategy of both contestants made Virginia the field on which the left wing of the Federal armies pivoted, while the right swung farther and farther south and east, and the Confederates gallantly struggled for every foot of territory, yielding only to the inexorable. This right wing had already possession of the Mississippi as far south as Vicksburg, around which place Grant was preparing to tighten his coils; it had occupied the line of the Tennessee River, and had rendered useless to the Confederates the railroad from Memphis to Chattanooga, which had been the great central artery between Richmond and the trans-Mississippi States. The Southern partisans, with Morgan and Forrest as typical chiefs, had up to this period played, in the West especially, a very important part. They as much exceeded our cavalry in enterprise as they had advantage over it in knowledge of the country and in assistance from its population. They had on more than one occasion tapped the too long and slender lines of operation of our foremost armies. They had sent Grant to the right-about from his first march on Vicksburg, thus neutralizing Sherman's attempt at Chickasaw Bayou. They had compelled Buell to forfeit his hardly-earned footing, and to fall back from the Tennessee River to Louisville at the double-quick in order to beat Bragg in the race towards the gate of the Northern States, which disaster was happily soon retrieved by the latter's bloody check before Murfreesborough. Yet, despite these back-sets, the general course of events showed that Providence remained on the side of the heaviest battalions; and the spring of 1863 saw our armies extended from the pivot midway between the rival capitals in a more or less irregular line, and interrupted by the Alleghany Mountains, to Vicksburg and the Father of Waters.
