Lincoln and McClellan’s Fatigued Horses

Tired and Fatigued horsesI have just read your dispatch about sore tongued and fatigued horses. Will you pardon me for asking what the horses of your army have done since the battle of Antietam that fatigue anything? A. LINCOLN

General George B. McClellan was at it again. Or not at it, in a sense. McClellan had a habit of overestimating the enemy troop numbers and underestimating his own ability to attack. Lincoln was constantly frustrated.

In September 1862, Confederate General Robert E. Lee led his Army of Northern Virginia into western Maryland. Following their victory at a second battle of Bull Run, Lee moved his army north to a point near Sharpsburg, alongside Antietam Creek, where they took up defensive positions. With surprising aggressiveness, McClellan’s Army of the Potomac attacked Lee’s forces on September 17. The first assault came from Union General Joseph Hooker on Lee’s left flank, while General Ambrose Burnside later attacked the right. A surprise counterattack from Confederate General A.P. Hill helped push back Union forces. Eventually, Lee’s troops withdrew from the battlefield first. He moved his remaining army back across the Potomac into the safety of Virginia.

Always overly cautious, McClellan made no effort to follow. Lee had committed all of his 55,000 men, while McClellan only ordered a portion of his larger 87,000-man force into the fray. This numerical imbalance allowed Lee to create and exploit tactical advantages he should not have had. When questioned by Lincoln about his failure to pursue Lee, McClellan complained that his army and horses were sore-tongued and fatigued, and thus required rest. Lincoln responded tersely by telegram:

Will you pardon me for asking what the horses of your army have done since the battle of Antietam that fatigue anything?

Antietam was destined to be the single bloodiest day of battle in American history. The casualties for both armies totaled a staggering 22,717 dead, wounded, or missing.

Despite Lincoln’s frustration, Antietam stood out as an important battle in the fight for freedom. Although essentially a draw, the fact that Lee withdrew from the battlefield first allowed the North to record Antietam as a victory, something that Lincoln had been needing for some time. A few days later, Lincoln issued the Emancipation Proclamation.
