Bragg returned to Tennessee. Gen. William S. Rosecrans, who had gained fame in two Mississippi campaigns, assumed command of the Federal army opposing Bragg. Then in November Grant started southward from Tennessee through Mississippi toward Vicksburg, the chief Confederate stronghold on the “Father of Waters.” Grant’s strategy called for a two-pronged attack: he and Gen. William T. Sherman would deliver simultaneous assaults on Vicksburg from different directions. The plan was a costly failure. Confederate cavalry under Gen. Earl Van Dorn destroyed Grant’s main supply base at Holly Springs. Grant was forced to fall back to Memphis. Sherman’s assaults on December 28-29 at Chickasaw Bayou were repulsed with heavy losses. Grant then moved his entire army down the Mississippi and prepared to take Vicksburg by attack or siege. The final Western engagement of 1862 began on the last day of the year near Murfreesboro, Tenn. For the better part of four days Bragg’s Confederate army waged a desperate fight along the banks of Stone’s River with Rosecrans’s Federal forces. Tactically the battle was a draw. Yet the Federals lost 31% in killed, wounded, and missing, while the Confederates suffered 25% casualties. 1862 IN THE EAST For seven months McClellan’s large army lay inactive around Washington. Finally Lincoln, his patience exhausted, ordered McClellan to advance into Virginia. McClellan dismissed the dangerous overland route to Richmond. Rather, he proposed to transport his forces by water to Fort Monroe. Thence he would advance westward on Richmond by way of the same peninsula where Butler had met defeat the preceding year. This was the framework of the Peninsular Campaign. [Illustration: The creation of the Army of the Potomac was the work largely of George B. McClellan. In 1864 he ran unsuccessfully as Democratic candidate for President.] Lincoln finally agreed to the plan. To protect Washington, however, he ordered McDowell’s corps of 37,000 soldiers to remain in the Fredericksburg-Manassas area. By April McClellan was on the Virginia peninsula with 105,000 men. In the meantime, Gen. Joseph E. Johnston, commanding the Confederate forces in Virginia, had concentrated his small army on the peninsula between McClellan and Richmond. McClellan slowly advanced westward; Johnston, with only 60,000 men, had no choice but to fall back and fight delaying actions. Driving rains turned the country into a vast sea of mud. By the end of May McClellan’s army had reached Seven Pines. The spires of Richmond were visible, nine miles away.
