At one place the Federal forces had erected log breastworks. These caught fire during the battle and both forces fought each other over a line of fire through which neither could pass. From every thicket different flags waved. The forces were so mixed that men going back for water would find themselves in the hands of the enemy. In places the woods caught fire and men fought through the rolling smoke until driven back by the flames that spared neither the Blue nor the Gray. Both sides would then crawl out to rescue the wounded lying in the path of the fire. In some places where the men had fought through the brush, bushes, saplings and even large trees were cut off by bullets four or five feet from the ground as clean and regularly as if by machinery. For the first few days the Confederates had the advantage. They knew the paths and the Union men were driven back and forth among the woods in a way that would have made any ordinary general retreat. But Grant was not an ordinary general. The more he was beaten the harder he fought. The more men he lost the more he called into action from the reserves. "It's no use fighting that fellow," said one old Confederate veteran; "the fool never knows when he's beaten. And it's no use shooting at those Yanks," he went on; "half-a-dozen more come to take the place of every one we hit." At last the Union soldiers got the lay of the land. They couldn't be surprised or ambushed any more. Then they began to throw up breastworks and to cut down trees to hold every foot that they had taken. The Confederates did the same and the two long, irregular lines of earthworks and log fortifications faced each other all the way through the Wilderness. Yet still the lines of gray lay between Richmond and the men in blue. For six days the men had fought locked together in hand-to-hand fights over miles and miles of wilderness, marsh and thicket. The Union losses had been terrific. All along the line the Confederates had won and again and again had dashed back the attempts of the Union forces to pass through or around their lines. The Union Army had lost eleven officers and twenty thousand men and had fought for six days without accomplishing anything. Yet on that day Grant sent to Washington a dispatch in which he wrote: "I propose to fight it out on this line if it takes all summer."
