American Civil War: The Battle of Vienna, Virginia, took place, which involved one of the world's first military movements of troops by train.

The American Civil War was a civil war in the United States between the Union and the Confederacy, which was formed in 1861 by states that had seceded from the Union. The central conflict leading to war was a dispute over whether slavery should be permitted to expand into the western territories, leading to more slave states, or be prohibited from doing so, which many believed would place slavery on a course of ultimate extinction.

The Battle of Vienna, Virginia was a minor engagement between Union and Confederate forces on June 17, 1861, during the early days of the American Civil War.
