Depiction of Ball's Bluff by Alfred W. Thompson

Date: October 21, 1861
Location: Loudoun County, Virginia
Result: Confederate victory

The Battle of Ball's Bluff (also known as the Battle of Leesburg or Battle of Harrison's Island) was an early battle of the American Civil War fought in Loudoun County, Virginia, on October 21, 1861, in which Union Army forces under Major General George B. McClellan suffered a humiliating defeat.

The operation was planned as a minor reconnaissance across the Potomac to establish whether the Confederates were occupying the strategically important position of Leesburg. A false report of an unguarded Confederate camp encouraged Brigadier General Charles Pomeroy Stone to order a raid, which resulted in a clash with enemy forces. A prominent U.S. Senator in uniform, and dear friend of the Lincoln family, Colonel Edward Baker, tried to reinforce the Union troops, but failed to ensure that there were enough boats for the river crossings, which were then delayed. Baker was killed, and a newly arrived Confederate unit routed the rest of Stone's expedition.

The Union losses, although modest by later standards, alarmed Congress, which set up the Joint Committee on the Conduct of the War, a body which would provoke years of bitter political infighting.

On the morning of October 21, Colonel Devens' raiding party discovered the mistake made the previous evening by the patrol; there was no camp to raid. Opting not to recross the river immediately, Devens deployed his men in a tree line and sent a messenger back to report to Stone and get new instructions. On hearing the messenger's report, Stone sent him back to tell Devens that the remainder of the 15th Massachusetts (another 350 men) would cross the river and move to his position. When they arrived, Devens was to turn his raiding party back into a reconnaissance and move toward Leesburg.

While the messenger was going back to Col. Devens with this new information, Colonel and U.S. Senator Edward Dickinson Baker showed up at Stone's camp to find out about the morning's events. He had not been involved in any of the activities to that point. Stone told him of the mistake about the camp and about his new orders to reinforce Devens for reconnaissance purposes. He then instructed Baker to go to the crossing point, evaluate the situation, and either withdraw the troops already in Virginia or cross additional troops at his discretion.

On the way upriver to execute this order, Baker met Devens' messenger coming back a second time to report that Devens and his men had encountered and briefly engaged the enemy, one company (Co. K) of the 17th Mississippi Infantry. Baker immediately ordered as many troops as he could find to cross the river, but he did so without determining what boats were available to do this. A bottleneck quickly developed so that Union troops could only cross slowly and in small numbers, making the crossing last throughout the day.

Meanwhile, Devens's men (now about 650 strong) remained in its advanced position and engaged in two additional skirmishes with a growing force of Confederates, while other Union troops crossed the river but deployed near the bluff and did not advance from there. Devens finally withdrew around 2:00 p.m. and met Baker, who had finally crossed the river half an hour later. Beginning around 3:00 the fighting began in earnest and was almost continuous until just after dark.

Col. Baker was killed at about 4:30 p.m. and remains the only United States Senator ever killed in battle. Following an abortive attempt to break out of their constricted position around the bluff, the Federals began to recross the river in some disarray. Shortly before dark, a fresh Confederate regiment (the 17th Mississippi) arrived and formed the core of the climactic assault that finally broke and routed the Union troops.

Many of the Union soldiers were driven down the steep slope at the southern end of Ball's Bluff (behind the current location of the national cemetery) and into the river. Boats attempting to cross back to Harrison Island were soon swamped and capsized. Many Federals, included some of the wounded, were drowned. Bodies floated downriver to Washington and even as far as Mount Vernon in the days following the battle. A total of 223 Federals were killed, 226 were wounded, and 553 were captured on the banks of the Potomac later that night. The official records incorrectly state that only 49 Federals were killed at this battle, an error probably resulting from a mistaken reading of the report of the Union burial detail which crossed over the next day under flag of truce. Fifty-four Union dead—of whom only one is identified—are buried in Ball's Bluff Battlefield and National Cemetery. A Union howitzer captured by Confederate forces was recaptured May 29, 1863 from John S. Mosby raid at Greenwich, Virginia.
