DEATH OF GENERAL POLK.

The plan of Sherman was to shut off Atlanta from the rest of the world. By thus excluding its supplies, it would be starved into submission, as was the case at Vicksburg. Accordingly, he began a series of works, intended to be extended gradually around the city. This was difficult and dangerous, as was proven when two columns of Union cavalry, failing to effect a junction, through some misunderstanding, were separately attacked and routed. Among the many prisoners taken was General Stoneman, and the cavalry arm of the service was greatly weakened.

The impetuous Hood made a furious onslaught upon the Union army July 28th, renewing it several times, but was defeated with heavy loss in each instance. Sherman, through the failure of one of his generals to reach his assigned position in time, narrowly missed bagging Hood and his whole army.

FALL OF ATLANTA.

But Sherman displayed masterly generalship by so manœuvring as to draw Hood away from the defenses and by thrusting his army between the corps of Hardee and Atlanta. The only escape now for the Confederates was to abandon the city, which was done on the 1st of September, many of the citizens going with the retiring army. At nine o'clock the next morning General Slocum, at the head of a strong reconnoitering column, rode into Atlanta, and the mayor made a formal surrender of the place.

The news of the fall of Atlanta caused great rejoicing in the North, and corresponding depression in the South. President Davis hurried to the neighborhood to investigate for himself. He found matters so bad that they could not be much worse. Hood, however, was as combative as ever, and proposed to attack Sherman's lines of communication. It was a dangerous proceeding, but Davis consented. On his way back to Richmond he stopped at Macon and made a speech, in which he announced the plans of Hood. This speech was published in the Southern papers, reached the North, where it was republished, and in due time these papers went to Sherman, It can well be understood that Davis' speech proved "mighty interesting" reading to the Union commander.

FAILURE OF HOOD'S PLAN FOR THE RELIEF OF GEORGIA.

Hood's plan was simple. He proposed to march into Tennessee, and, by threatening Sherman's communications, compel him to withdraw from Georgia. But Sherman was not to be caught thus easily. He followed Hood to the north of the Chattahoochee, and, then letting him go whither he chose, turned back to Atlanta. Hood kept right on through northern Alabama, and advanced against Nashville. General Thomas had been sent by Sherman from Atlanta, with the Army of the Cumberland, to look after Hood. General Schofield, in command in the southern part of the State, fell back to Franklin, eighteen miles south of Nashville, where he was attacked November 30th by Hood. It was a savage battle, but the Confederates were held in check until night, when Schofield retreated across the river, and took refuge in Nashville. There General Thomas gathered all his troops, and threw up a line of intrenchments to the south of the city. Hood appeared in front of them December 2d, and began building works and counter batteries. He was certain of capturing the place and its defenders by regular siege operations. Never did the genius of Thomas shine more brilliantly than at the siege of Nashville. He industriously gathered reinforcements, perfected his defenses, and refused to move until fully prepared. The whole country became impatient; even General Grant sent him urgent messages, and at one time issued an order for his removal. But Thomas could not be shaken from his purpose. Not until December 15th did he feel himself ready to strike, and then he did it with the might of a descending avalanche. He sallied forth, captured several redoubts, and drove back the Confederates for a number of miles. He renewed the battle on the 16th, and utterly routed Hood's army. The panic-stricken troops fled in confusion, drawing Forrest and his cavalry into the disorganized flight, while Thomas vigorously pursued until the fugitives scrambled over Duck River toward the Tennessee, which was crossed on the 27th of December.

Hood's army was virtually destroyed. He lost more than 13,000 prisoners, including several general officers, and many guns, while more than 2,000 deserters joined Thomas. The disgusted Hood asked to be relieved of his command, and Dick Taylor, who had defeated Banks some months before in Texas, assumed his place, but he really was left with no army to command. The proud host which had promised so much existed no longer. The Rock of Chickamauga had fallen upon it and ground it to powder.
