Again Lee had beaten his adversary in a race to secure the commanding ground at the place of meeting. He had placed his army in a position where it could be assailed only in front, and the men, who had learned the use of spade and shovel as expertly as they already knew the use of the bullet and the bayonet, had been favored by the nature of the soil in throwing up a line of breastworks which they felt themselves competent to hold against any assault. Lee's right rested on the Chickahominy river, and his left upon a maze of little streams between which there were impracticable swamps. The river in his rear was at that season very low and easily fordable at almost any point at which a crossing might be attempted, so that it offered no barrier to a retreat of the Confederates, if retreat should be forced upon them. Best of all, as a source of confidence to Lee was the superb morale of his army. It might be possible for an enemy to carry his works and force a way through his lines though that was exceedingly improbable in view of the stubbornness with which his Confederates had learned to fight. But even should that improbable thing be accomplished, Lee perfectly knew that his men would none of them run away, but that they would stand fast by their colors, and fall back fighting to the works before Richmond. The time had completely gone by when panic or demoralization was to be reckoned upon as even a possible factor in either of these two veteran armies. They had both of them thoroughly learned the trade of war. They were both composed of as good human material as was ever employed in the construction of an army. They were both commanded from top to bottom by officers who knew their business, and were disposed to do it at their best.
Here, then, were all the conditions for a great battle and it was for Grant to determine whether or not that battle should be fought. His critics have contended that he should have determined that question in the negative—that the position of Lee was too strong to invite direct assault, or to offer his assailant a tolerable chance of victory. It was at any rate certain, that no assault could be made which would not involve tremendous slaughter among the assailants, while no assault unless successful beyond any promise that the conditions held forth could possibly inflict upon the Confederates any compensating loss, even if reckoned upon the arithmetical hypothesis that Grant could afford to lose two or three men to his adversary's one.
Writing near the end of his life, General Grant said in his "Memoirs":
"I have always regretted that the last assault at Cold Harbor was ever made.... At Cold Harbor no advantage whatever was gained to compensate for the heavy loss we sustained. Indeed the advantages other than those of relative losses were on the Confederate side."
But the assault was made. In spite of the adverse conditions, Grant determined to assail Lee there, and if possible to force a passage through his lines. It should be explained that during all these movements the two armies had kept themselves always within striking distance of each other, and that conflicts between them had occurred at every step—conflicts which earlier in the war would have been reckoned as battles of great moment, but which at this stage of the struggle were regarded merely as passing incidents of a campaign marked by tremendous battles. At Cold Harbor there was very heavy fighting on the second of June, when Lee took the offensive and bent back the right of Grant's line, thus greatly strengthening the Confederate position of defense.
The great battle came, however, on the morning of the third of June, just as the darkness of night began to gray into the dawn. There was no strategy employed in this action. There was nothing in it of tactics, grand or petty. As one historian has said, it was a fierce battle depending for its results "upon the brute strength of the forces engaged." Grant simply hurled nearly his whole army against Lee at a single point. The fighting covered scarcely more than a brigade front of Lee's line, and upon that short front Lee promptly concentrated troops until they stood six deep at the breastworks, the men in rear loading rifles, and passing them to those in front to fire. The Federals were advancing against strong earthworks, and through a tangled mass of abattis or trees felled with their branches toward the enemy, and with their limbs sharpened to obstruct a march.
The action lasted scarcely more than twenty minutes. Yet in that brief time Grant lost, according to his own report, 10,500 men, or at the rate of more than five hundred men per minute, or nearly ten men per second. When General Lee sent a messenger to General A. P. Hill, who commanded at that point, to ask for a report of the results Hill pointed to the dead bodies of Federal troops piled high upon each other, and for answer said, "Tell General Lee it is the same all along my front."
The Confederate loss in this action was reported at about 1,000 men.
This was the most staggering blow that Grant had ever received in battle, and the news of it appalled the authorities at Washington, and greatly depressed the people throughout the North. That a little army like Lee's, reduced by this time to less than 50,000 men, should have inflicted such a defeat upon an adversary whose forces were generally estimated at 120,000 men seemed to those persons who do not understand the conditions of battle to indicate a lack either of commanding capacity on the part of General Grant or of fighting capacity on the part of the army under his command.
Both of these judgments were clearly mistaken. It was perhaps an error on General Grant's part to assail Lee in his strong position at Cold Harbor, but it was a mistake prompted by that boldness which so often achieves conspicuous results in war. In criticizing such operations it is always necessary to bear in mind that "war is a hazard of possibilities, probabilities, luck and ill luck." At Cold Harbor there was, to say the least, a possibility that Grant, with his overwhelmingly superior numbers, might break through the Confederate lines, and force his way into Richmond. There was the hazard of such failure as that which the Federal army in fact met with. For the sake of the possibility Grant accepted the hazard. Had he won there would have been nothing but praise throughout the North for a boldness which had achieved so conspicuous a success. As he lost in the hazard instead, there was bitter criticism which has not ceased even unto this day.
