The Battle of Iuka was fought on September 19, 1862, in Iuka, Mississippi, during the American Civil War. In the opening battle of the Iuka-Corinth Campaign, Union Brigadier General William S. Rosecrans stopped the advance of the Confederate Army of the West commanded by Maj. Gen. Sterling Price. Union Major General Ulysses S. Grant brought two armies to confront Price in a pincer movement: a double envelopment, with Rosecrans' Army of the Mississippi approaching Iuka from the southwest, and three divisions of their own Army of the Tennessee, under Maj. Gen. Edward Ord, approaching from the northwest. Such a movement was difficult to pull off during the Civil War, especially in bad terrain such as at Iuka, because it required that both jaws of the pincer reach the enemy at the same time, and in the early days of the war, before telegraph communications had been become sufficiently sophisticated, other methods of coordination needed to be used, in this case, the sound of the battle starting.
