Lincoln’s plan was gradually to shut the South in, driving it behind its own boundaries by means of the armies invading from north and west, and blockading the ports from the sea. So far the first half of the plan was not successful. But the Civil War was won to a very large extent by the Northern navy. By blockading the Southern ports it prevented the South from getting supplies from Europe; and since the South depended for supplies of every sort from abroad, it was in a desperate position when cut off from the sea. More fortunate on sea than on land, Lincoln found in David Farragut an admiral almost as great as Nelson. Farragut was a Southerner by birth, but he had served for fifty years in the United States navy, and refused to desert it now. Patriotism to him meant devotion not to the pride but to the best interests of his country, and he thought that North and South could only attain their best interests when united. In April the Northern army suffered a severe defeat on land at the battle of Shiloh--the most disastrous yet experienced; but the news was balanced by the tidings of Farragut’s capture of New Orleans. The fighting in the harbour was tremendous. “Don’t flinch from that fire, boys,” cried the admiral; “there is a hotter fire for those who don’t do their duty!” Inspired by his example, his men did not flinch, and the town was captured. The North needed all the encouragement such naval victory could give it, for things were going very badly. Stonewall Jackson, the Southern commander, carried everything before him in Virginia. Washington was in danger; there was a panic in the capital. Jackson, however, did not want to attack Washington. His plan was to compel M’Clellan, who was slowly moving south to attack the Confederate capital at Richmond, to turn north again. There was fighting all through June; Jackson had been joined by Lee, the Confederate Commander-in-Chief. On the 1st of July a battle was fought at Malvern Hill. Lee and Jackson were defeated. M’Clellan ought now to have pushed on to Richmond, the Confederate capital, instead of which, with extraordinary stupidity, he continued to retreat. In August, the second battle of Bull Run resulted in another victory for the South. Both sides lost an extraordinary number of men. The panic in Washington grew more acute when, early in September, Lee prepared to invade Maryland. M’Clellan again delayed when he ought to have forced an engagement. The people of Maryland received the Southern army very coldly. On the 17th the armies met at Antietam. The battle was not really decisive; the losses of the North were as great as those of the South; but it put an end to their invasion. Lee recrossed the Potomac River to Virginia. M’Clellan again wasted time. He waited six weeks before pursuing Lee. In November M’Clellan was at last superseded.
