Breckinridge received his orders on the 26th, and arrived at Camp Moore by the railway on the 28th. At Jackson he had been told that he would receive rations sufficient for ten days, but he could get no more than half the quantity. Van Dorn had estimated the Union force to be met at Baton Rouge as about 5,000, and had calculated that Breckinridge would find himself strong enough to dislodge the Union army and drive it away. In fact, Van Dorn estimated Breckinridge's division, including 1,000 men under Brigadier-General Ruggles that were to meet him at Camp Moore, at 6,000 men. The _Arkansas_ was to join in the attack, and she was justly considered a full offset to any naval force the Union commander would be likely to have stationed at Baton Rouge. Breckinridge left Vicksburg with less than 4,000. On the 30th of July he reports his total effective force, including Ruggles, at 3,600. The same day he marched on Baton Rouge, and on the 4th of August encamped at the crossing of the Comite, distant about ten miles from his objective. His morning report of that day shows but 3,000 effectives, according to the methods by which effective strength was commonly counted by the Confederates. The distance from Camp Moore to Baton Rouge is about sixty miles, and the march had been thus retarded to await the co-operation of the _Arkansas_. This Breckinridge was finally assured he might expect at daylight on the morning of the 5th of August. The _Arkansas_ had in fact left Vicksburg on the 3d. Van Dorn's object obviously was by crushing Williams to regain control of the Mississippi from Vicksburg to Baton Rouge, to break the blockade of Red River and to open the way for the recapture of New Orleans. Williams was expecting the attack and awaited the result with calmness. At Baton Rouge the Mississippi washes for the last time the base of the high and steep bluffs that for so many hundreds of miles have followed the coasts of the great river and formed the contour of its left bank, overlooking its swift yellow waters and the vast lowlands of the western shore. The bluff is lower at Baton Rouge than it is above and slopes more gently to the water's edge; and here the highland draws back from the river and gradually fades away in a southeasterly direction toward the Gulf, while the surface of the country becomes more open and less broken. The stiff post-tertiary clays that compose the soil of these bluffs were in many places covered with a rich growth of timber, great magnolias and beautiful live oaks replacing the rank cottonwood and tangled willows of the lowlands, as well as the giant cypresses of the impenetrable swamps, with their mournful hangings of Spanish moss, and the wild grape binding them fast in a deadly embrace.
