The North conducted the war upon three great lines of campaign: 1. The Western campaigns, to clear the Mississippi River and thus divide the Confederacy. 2. The campaigns in the centre, to reach the sea at Mobile, Savannah, or Charleston, cutting the Confederacy a second time. 3. The Eastern campaigns, to take Richmond, and capture or destroy the main Confederate army, ending the Confederacy. This chapter deals with the Western campaigns alone. [1862] The opening of 1862 found the Confederates in possession of a strong line across the southern portion of Western Kentucky, stretching from Bowling Green, near the centre of the State, to Columbus on the Mississippi. The two gates of this line were Forts Henry and Donelson, on the Tennessee and Cumberland Rivers, respectively, just over the Tennessee border. If these forts could be taken the Confederates must give up Kentucky. On February 6th, after a two hours' bombardment, Fort Henry surrendered to General Grant, who had come up the river from Cairo with 17,000 troops, and with seven gunboats commanded by Commodore Foote. Most of the garrison, about 3,000, had been sent off before the fleet opened fire, General Tilghman foreseeing that he could not hold the fort. The land forces arrived too late to cut off their retreat, and they escaped safely to Fort Donelson, some dozen miles to the east. Grant marched at once to invest Donelson, and sat down before it on the 12th with 15,000 men. The stronghold stood upon a bluff 100 feet high. On the east it was protected by the Cumberland River; on the north and south by two flooded creeks. Along a crest back of the fort a mile or two ran a semicircular line of rifle-pits, with abatis in front. Nine batteries were posted at various points along the line. Donelson was garrisoned by 20,000 men under Generals Floyd, Pillow, and Buckner, who quietly looked on while Grant's smaller army hemmed them in. On the 14th the gunboats opened fire upon the water batteries between fort and river. Commodore Foote steamed up boldly within 400 yards and pounded the opposing works with his heavy guns. He did little damage, however, while the Confederate fire proved very effective against him. His flag-ship, the Hartford, was struck fifty-nine times. A shot crashed into the pilothouse, destroying the wheel and wounding Foote himself. The boat became unmanageable and drifted down-stream. A shot cut the tiller-ropes of the Louisville. The other boats were also considerably damaged, and after an action of an hour and a half, the entire fleet withdrew.
