The Battle of Chaffin's Farm is fought in the American Civil War.

The Battle of Chaffin's Farm and New Market Heights, also known as Laurel Hill and combats at Forts Harrison, Johnson, and Gilmer, was fought in Virginia on September 29–30, 1864, as part of the siege of Petersburg in the American Civil War.

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.
