Wars are generally long, bloody, and horrible affairs that everyone is anxious to wrap up so that everyone can go back home.
But for some reason, there have been wars that don’t end on time. Here are four times that the U.S. found itself in a battle after the war it was fighting was technically already over:
1. The Battle of New Orleans propels Maj. Gen. Andrew Jackson to nationwide fame after the War of 1812
The War of 1812 officially ended with the Treaty of Ghent on Dec. 24, 1814, but Maj. Gen. Andrew Jackson repelled an attack on Jan. 8, 1815, by approximately 8,000 British regulars who hadn’t yet heard about the treaty. Jackson’s defense of the city inflicted 2,000 casualties — including three generals and seven colonels — on the British and made Jackson an American hero.
Even that wasn’t the final battle of the supposedly terminated war. The British survivors of New Orleans launched another attack on nearby Fort St. Philip which failed and then a successful attack on Fort Bowyer in modern-day Alabama.
2. American Gen. Sterling Price fought an extra battle in Mexico because he didn’t believe the peace news
American Gen. Sterling Price had orders to hold and defend southern New Mexico near the end of the Mexican-American War — orders that he ignored to attack the city of Chihuahua in early 1848. When he arrived at the city, a group of citizens told him that the garrison had withdrawn from the town to avoid bloodshed as the war had ended with the Treaty of Guadalupe Hidalgo the previous month.
Price basically wrote the treaty off as fake news and just assaulted south anyway, catching up to the Mexican forces at the city of Santa Cruz de Rosales. The Mexican commander attempted to defend the town, repelling attacks from the north and west but falling to a thrust from the south.
3. The Battle of Palmito Ranch may have been a colonel trying to pop his combat cherry before the war ended
While there was no official peace treaty ending the Civil War, everyone had pretty much agreed it was over by May 1865. Lincoln was dead, the Confederate cabinet was scattered, and the War Department was getting ready to release most of the Union Army from the service.
But Union Col. Theodore H. Barrett found himself occupying an island near Confederate forces who were slowly negotiating a surrender with a major general. Rather than let those negotiations play out, Barrett led his regiment against the Confederate forces despite the fact that he had no combat experience and no orders to do so.
The blow-by-blow of the battle is farcical where it isn’t boring, but it basically amounts to a useless Union defeat at the hands of barely interested rebels and some French soldiers who were stationed in Mexico just across the river. Barrett later claimed the defeat was the fault of another colonel, but a court martial supported no charges against the other officer.
4. The last troops to die in the Vietnam War fought weeks after the war ended and two years after America withdrew
While the American involvement in the Vietnam War officially ended with the 1973 Paris Peace Accords, the actual war drew on for another two years until South Vietnam surrendered to Communist North Vietnam on April 30, 1975.
But the final battle involving American troops took place from May 12 to 15. The Khmer Rouge, a communist military group that had recently seized Cambodia, captured the crew of the U.S. merchant ship SS Mayaguez and President Gerald Ford deployed sailors, Marines, and airmen to rescue them.
The operation suffered from a lack of intelligence and the Marines hit the wrong island, one that was being guarded by 150 to 200 dug-in fighters when the Marines expected light resistance. America lost 41 Marines and airmen killed and wounded, but recovered the ship and the crew.
