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 The engagement is also known as the Battle of Harrison’s Island or the Battle of Leesburg. Aftermath This Union defeat was relatively minor in comparison to the battles to come in the war, but it had an enormously wide impact in and out of military affairs. In addition to losing 223 soldiers, the Union lost a sitting senator, which led to severe political ramifications in Washington. Stone was treated as the scapegoat for the defeat, but members of Congress suspected that there was a conspiracy to betray the Union. The ensuing outcry, and a desire to learn why Federal forces had lost battles at Bull Run (Manassas), Wilson's Creek, and Ball's Bluff, led to the establishment of the Congressional Joint Committee on the Conduct of the War, which would bedevil Union officers for the remainder of the war (particularly those who were Democrats) and contribute to nasty political infighting among the generals in the high command. Lt. Oliver Wendell Holmes, Jr., of the 20th Massachusetts Volunteer Infantry, survived a nearly fatal wound at Ball's Bluff to become an Associate Justice of the Supreme Court of the United States in 1902. Herman Melville's poem "Ball's Bluff – A Reverie" (published in 1866) commemorates the battle. Holmes' great friend and role model, Lt. Henry Livermore Abbott also survived the battle but did not survive the war. In 1865, Abbott was posthumously promoted to Brigadier General. Another outstanding young officer named Edmund Rice also eventually reached the rank of Brigadier General, was awarded the Medal of Honor and was fortunate enough to survive the war by near a half century. 2nd Lt. John William Grout of the 15th Massachusetts was killed in the battle; his death inspired a poem (and later a song) titled "The Vacant Chair". Battlefield preservation The site of the battle is preserved as the Ball's Bluff Battlefield and National Cemetery, which was declared a National Historic Landmark in 1984. The park is maintained by the Northern Virginia Regional Park Authority. The battlefield area
