Commodore Foote’s gunboats ascending the Tennessee to attack Fort Henry.
Various plans for an attack upon the Confederate line were considered by the Federals. General Halleck, commander of the Department of the Missouri, believed that it would take an army of not less than 60,000 men, under one commander, to break the well-established line. He, therefore, asked that General Buell’s army be transferred to him, or at least placed under his command.
Before a union of the two departments could be effected, General Grant asked for, and received, permission to attack the line at Fort Henry. A combined land and naval attack by Grant’s troops and the gunboat fleet of Commodore Andrew H. Foote resulted in the surrender of Fort Henry on February 6, 1862, and the capture of Fort Donelson, with about 12,000 prisoners, on the 16th. The loss of these forts broke Johnston’s line at its center and compelled him to evacuate Bowling Green and Columbus, permitting western Kentucky to fall into Union hands. To prevent encirclement, he was also forced to withdraw from Nashville, abandon Middle and West Tennessee, and seek a new line on the Memphis and Charleston Railroad.
Following the fall of Forts Henry and Donelson, Grant incurred the displeasure of General Halleck by sending a division of troops into Buell’s department at Clarksville. Halleck’s indignation increased when he learned that Grant had gone to Nashville for consultation with Buell. Halleck directed the withdrawal of the division from Clarksville, suspended Grant from command, and ordered him to Fort Henry to await orders.

The army under Grant’s successor, Gen. Charles F. Smith, moved up the Tennessee toward the heart of the Confederacy, with the intention of rendezvousing at Savannah, Tenn., on the east side of the river. Gen. William T. Sherman was sent forward on the so-called Yellow Creek Expedition for the purpose of destroying railroad communications to the west of Corinth, Miss., the objective of the campaign. High water made Sherman’s mission a failure, and he was compelled to return. He reported to General Smith that a more convenient place for the assembling of his army was at Pittsburg Landing, Tenn., 9 miles above Savannah, and on the west side of the river, from which direct roads led to Corinth. General Smith, therefore, instructed him to disembark his division and that of Gen. Stephen A. Hurlbut at Pittsburg Landing, in positions far enough back to afford room for the other divisions of the army to encamp near the river.
