The Battle of Pea Ridge, fought March 7–8, 1862 in northwest Arkansas, was one of the key engagements in the Trans‑Mississippi theater of the American Civil War. Often called the Battle of Elkhorn Tavern after a prominent landmark on the field, it ended in a clear Union victory that helped secure Missouri for the United States and shaped operations across the western border states. For general context see background on the campaign.
Commanders and forces
Union forces in the field were led by Major General Samuel R. Curtis. Confederate troops were under the overall direction of Major General Earl Van Dorn, with important roles played by commanders such as Major General Sterling Price and Brigadier General Benjamin McCulloch. The Confederate plan depended on coordinated movements and a flank attack; when that coordination failed the Confederate effort lost momentum. Further reading on leaders and orders of battle is available at leadership and unit details.
The fight and tactical features
The fighting unfolded across rolling Ozark terrain, wooded ridges and open fields around Elkhorn Tavern. Confederate attempts to turn the Union flank met stiff resistance and were hampered by the death and wounding of several Confederate officers, which disrupted command on the field. Union forces held defensive ground and counterattacked at critical moments, ultimately forcing Van Dorn to withdraw. A contemporary map and battlefield tour notes can be found at battle maps and tours.
Outcome and significance
Although not the largest battle of the war, Pea Ridge had strategic consequences: it removed the immediate Confederate threat to Missouri and consolidated Union control in the region. The engagement demonstrated how leadership losses, supply problems and coordination failures could decide campaigns, especially in the more isolated Trans‑Mississippi theater.
