General Grant was deeply moved at the terrible loss of life. When he expressed his regret for the heavy sacrifice of men to General Meade, the latter replied, "General, we can't do these little tricks without heavy losses." The total loss to the Union army in killed, wounded, and missing at Spotsylvania was nearly eighteen thousand. The Confederate losses have never been positively known, but from the best available sources of information the number has been placed at not less than nine thousand men. Lee's loss in high officers was very severe, the killed including General Daniel and General Perrin, while Generals Walker, Ramseur, R. D. Johnston, and McGowan were severely wounded. In addition to the loss of these important commanders, Lee was further crippled in efficient commanders by the capture of Generals Edward Johnson and Steuart. The Union loss in high officers was light, excepting General Sedgwick on the 9th. General Webb was wounded, and Colonel Coon, of the Second Corps, was killed. Lee's forces had been handled with such consummate skill as to make them count one almost for two, and there was the spirit of devotion for Lee among his soldiers which was indeed practically hero-worship. All in all, he had an army, though shattered and worn, that was almost unconquerable. Grant found that ordinary methods of war, even such as he had experienced in the West, were not applicable to the Army of Northern Virginia. The only hope for the Union army was a long-drawn-out process, and with larger numbers, better kept, and more often relieved, Grant's army would ultimately make that of Lee's succumb, from sheer exhaustion and disintegration. The battle was not terminated on the 12th. During the next five days there was a continuous movement of the Union corps to the east which was met by a corresponding readjustment of the Confederate lines. After various maneuvers, Hancock was ordered to the point where the battle was fought on the 12th, and on the 18th and 19th, the last effort was made to break the lines of the Confederates. Ewell, however, drove the Federals back and the next day he had a severe engagement with the Union left wing, while endeavoring to find out something of Grant's plans. Twelve days of active effort were thus spent in skirmishing, fighting, and countermarching. In the last two engagements the Union losses were nearly two thousand, which are included in those before stated. It was decided to abandon the attempt to dislodge Lee from his entrenchments, and to move to the North Anna River. On the 20th of May the march was resumed. The men had suffered great hardships from hunger, exposure, and incessant action, and many would fall asleep on the line of march.
