In the tangled underwood of the Wilderness artillery and cavalry were of little use, and the battle became a fierce struggle between the foot soldiers of either army. The forest was so thick that officers could only see a small part of their men, and could only guess at what was going on by the sound of the firing, and the shouts exultant or despairing, of the men who were drive to and fro in the dark and dreary thickets. In the end neither side gained anything except an increased respect for the foe.

Grant's aim was to take Richmond, the Confederate capital, and after the battle of the Wilderness with that aim still before him he moved his army to Spotsylvania. He was hotly pursued by Lee and here on the 10th and 12th of May another stern struggle took place.

The fighting on the 10th was so terrible that on the 11th both armies rested as by common consent. Next day the battle began again and lasted until midnight. It was a hand-to-hand struggle. The tide of victory swung this way and that. Positions were taken and lost, and taken again and after twenty-four hours of fighting neither side had won. Only thousands of brave men lay dead upon the field.

Still intent on Richmond, Grant moved southwards after this terrible battle, followed closely by Lee. Everyday almost there were skirmishes between the two armies, but still Grant pressed onward and arrived at length within a few miles of Richmond. Here at Cold Harbor Lee took up a strongly entrenched position from which it seemed impossible to oust him, except by a grand assault. Grant determined to make that assault.

Both officers and men knew that it could not succeed, but Grant commanded it and they obeyed. Yet so sure were many of the men that they were going to certain death that it is said they wrote their names and addresses on slips of paper which they tacked to the backs of their coats, so that when their bodies were found it might be easily known who they were, and news be sent to their friends.

At half-past four in the grey morning light eighty thousand men rushed upon the foe. They were met with a blinding fire and swept away. In half an hour the attack was over. It was the deadliest half hour in all American history, and eight thousand Union men lay dead upon the field.

"Some one had blundered." Grant had blundered. He knew it, and all his life after regretted it. "No advantage whatever was gained," he said, "to make up for the heavy loss we suffered."

In this terrible campaign he had lost sixty thousand men. He had not taken Richmond. He had neither destroyed nor dispersed Lee's army. Still he hammered on, hoping in the long run to wear out Lee. For the Confederates had lost heavily, too, and they had no more men with which to make good their losses. On the other hand the gaps in the Federal army were filled up almost as soon as made. "It's no use killing these fellows," said the Confederates, "a half dozen take the place of every one we kill."

But the people of the North could not look on calmly at these terrible doings. They cast their idol down, and cried out against Grant as a "butcher." They demanded his removal. But Lincoln refused again to listen to the clamour as he had refused before. "I cannot spare that man," he said, "at least he fights."

Grant was terrible only for a good end. He was ruthless so that the war might be brought the more speedily to a close. And Lincoln, the most tender hearted of all men, knew it. Undismayed therefore Grant fought on. But his army was weary of much fighting, disheartened by ill success, weakened by many losses. New recruits indeed had been poured into. But they were all unused to discipline. Months of drill were needed before they could become good soldiers. In June then Grant settled down to besiege Petersburg, and drill his new men the while, and not till the spring of 1865 did the army of the Potomac again take the field.
