Immediately following the Battle of Pea Ridge, General P. G. T. Beauregard, acting for General Albert S. Johnston, ordered General Earl Van Dorn to bring his Army of the West to Corinth, Mississippi, to join Johnston's force for an attack on the Union Army at Shiloh, Tennessee. Additionally General Van Dorn moved all the supplies he could, including the machinery and stores at the Little Rock Arsenal, to northern Mississippi with him, and left few men behind. However, due to bad roads Van Dorn failed to reach Corinth until a week after the Battle of Shiloh.
