14. On the 1st of January General Magruder captured Galveston, Texas. By this means the Confederates secured a port of entry in the Southwest. On the 7th of April Admiral Du Pont, with a fleet of iron-clads, attempted to capture Charleston, but was driven back. In June the city was besieged by a strong land-force, under General Q. A. Gillmore, assisted by Admiral Dahlgren's fleet. After the bombardment had continued for some time, General Gillmore, on the 18th of July, attempted to carry Fort Wagner by assault, but was repulsed with severe loss. The siege progressed until the 6th of September, when the Confederates evacuated the fort and retired to Charleston. Gillmore now brought his guns to bear on the wharves and buildings in the lower part of the city. But Charleston still held out; and the only gain of the Federals was the establishment of a complete blockade. [Sidenote: =Battle of Chancellorsville.=] 15. After his repulse at Fredericksburg, General Burnside was superseded by General Joseph Hooker, who, in the latter part of April, crossed the Rappahannock and reached Chancellorsville. Here, on the morning of the 2d of May, he was attacked by the Army of Northern Virginia, led by Lee and Jackson. The latter general, at the head of twenty-five thousand men, outflanked the Union army, burst upon the right wing, and swept everything to destruction. But it was the last of Stonewall Jackson's battles. As night came on the Confederate leader received a volley _from his own lines_, and fell to rise no more. [Illustration: Stonewall Jackson.] 16. On the 3d the battle was renewed. General Sedgwick was defeated and driven across the Rappahannock. The main army was crowded between Chancellorsville and the river, where it remained until the 5th, when General Hooker succeeded in withdrawing his forces to the northern bank. The Union losses amounted in killed, wounded, and prisoners to about seventeen thousand; that of the Confederates was less by five thousand. 17. Next followed the cavalry raid of General Stoneman. On the 29th of April he crossed the Rappahannock with ten thousand men, tore up the Virginia Central Railroad, cut General Lee's communications, swept around within a few miles of Richmond, and then recrossed the Rappahannock in safety.
