Balfour House is an antebellum mansion located at the corner of Crawford Street and Cherry Street in Vicksburg, Mississippi.

Upon hearing his news, Smith announced loudly "This ball is at an end! The enemy is coming down river. The men had only seconds to bid loved-ones good-bye as they rushed away and reported to station. The Siege of Vicksburg had begun.
