[2] Read "The Third Day at Gettysburg" in Battles and Leaders of the Civil War, Vol. III, pp. 369-385. The field of Gettysburg is now a national park dotted with monuments erected in memory of the dead, and marking the positions of the regiments and spots where desperate fighting occurred. Near by is a national cemetery in which are interred several thousand Union soldiers. Read President Lincoln's beautiful Gettysburg Address. [3] With the exception of a small body of regulars, the Union armies were composed of volunteers. When it became apparent that the war would not end in a few months, Congress passed a Draft Act: whenever a congressional district failed to furnish the required number of volunteers, the names of able-bodied men not already in the army were to be put into a box, and enough names to complete the number were to be drawn out by a blindfolded man. In July, 1863, when this was done in New York city, a riot broke out and for several days the city was mob-ruled. Negroes were killed, property was destroyed, and the rioters were not put down till troops were sent by the government. [4] William Tecumseh Sherman was born in Ohio in 1820, graduated from West Point, and served in the Seminole and Mexican wars. He became a banker in San Francisco, then a lawyer in Kansas, in 1860 superintendent of a military school in Louisiana, and then president of a street car company in St. Louis. In 1861 he was appointed colonel in the regular army. He fought at Bull Run, was made brigadier general of volunteers, and was transferred to the West, where he rose rapidly. After the war, Grant was made general of the army, and Sherman lieutenant general; and when Grant became President, Sherman was promoted to the rank of general. He was retired in 1884 and died in 1891 at New York. [5] Joseph Eggleston Johnston was born in Virginia in 1807, graduated from West Point, and served in the Black Hawk, Seminole, and Mexican wars. When the Civil War opened, he joined the Confederacy, was made a major general, and with Beauregard commanded at the first battle of Bull Run. Johnston was next put in charge of the operations against McClellan (1862); but was wounded at Fair Oaks and succeeded by Lee. In 1863 he was sent to relieve Vicksburg, but failed. In 1864 he was put in command of Bragg's army after its defeat, and so became opposed to Sherman. [6] Early in October Hood had reached Dallas on his way to Tennessee. From Dallas he sent a division to capture a garrison and depots at Allatoona, commanded by General Corse. Sherman, who was following Hood, communicated with Corse from the top of Kenesaw Mountain by signals; and Corse, though greatly outnumbered, held the fort and drove off the enemy. On this incident was founded the popular hymn _Hold the Fort, for I am Coming_.
