General McClellan was of short, stout figure, but was of soldierly presence, graceful, and handsome-featured.
In their mounts neither of the great commanders lost anything of his admirable presence. Both were masters of the science but not of the art of war. Lee was successful in Virginia; McClellan in Maryland.
Unjust criticism has been passed upon the Confederate soldiers in the Maryland campaign, based principally upon the great number of absentees. To those who have spent their lives near the ranks of soldiers and learned from experience that there is a limit to physical endurance, explanation is not called for; to those who look upon the soldier as a machine, not even needing oil to facilitate motive power, I will say, try to put yourselves in the soldiers' places. Another point to be noted was, that in the Confederate ranks there were thousands of soldiers who had been wounded once, twice, and in some instances three times, who in any other service would have been on the pension-rolls at their comfortable homes.
Sickness and weakness that creep into an army from irregular food, collected in the stress of march, were no trifling impediments to the maintenance of our ranks in vigorous form.
When, in mature judgment, the historian builds monuments of words for the leaders of the campaign in Maryland, there will be flowers left for the private soldiers, and for the private soldiers' graves.
The full significance of Sharpsburg to the Federal authorities lay in the fact that they needed a victory on which to issue the Emancipation Proclamation, which President Lincoln had prepared two months before and had held in abeyance under advice of members of his Cabinet until the Union arms should win a success. Although this battle was by no means so complete a victory as the President wished, and he was sorely vexed with General McClellan for not pushing it to completion, it was made the most of as a victory, and his Emancipation Proclamation was issued on the 22d of September, five days after the battle. This was one of the decisive political events of the war, and at once put the great struggle outwardly and openly upon the basis where it had before only rested by tacit and covert understanding. If the Southern army had been carefully held in hand, refreshed by easy marches and comfortable supplies, the proclamation could not have found its place in history. On the other hand, the Southern President would have been in Maryland at the head of his army with his manifesto for peace and independence.
