Reckless, the Horse Who Carried More Than Ammunition

The story of Sergeant Reckless, the Korean War horse who carried ammunition through heavy fire, rescued wounded soldiers, and still found time to steal pancakes, coffee, and Hershey bars.

Some horses are bred to race, while others spend their days pulling carts or working on farms. Reckless, however, ended up carrying ammunition during one of the toughest battles of the Korean War. She eventually became the highest-ranking horse in U.S. military history. But before all that, she was just a young Korean mare called Flame of the Morning.

Reckless was born in South Korea in June 1948. Her owner, Kim Huk Moon, named her Ah Chim Hai, or Flame of the Morning, because of the white blaze on her face. She was supposed to be a racehorse, but life had other plans for her. When the Korean War started, racing came to a halt, and everything changed for everyone around her.

In October 1952, Lieutenant Eric Pedersen of the U.S. Marine Corps showed up at the Seoul Racecourse looking for a pack animal. His platoon operated 75mm recoilless rifles, and they needed someone to haul ammo across those steep mountains and muddy trails. Pedersen spent $250 of his own money to buy the little mare. Kim Huk Moon only agreed to sell her because he needed cash for an artificial leg for his sister, injured in a landmine blast.

The Marines named her Reckless, after the recoilless rifle she’d be supplying. At first, someone had to guide her around. But soon, she barely needed any help. Reckless figured out the routes between the ammo dumps and the firing positions so well that she could often make those trips on her own. Once the Marines loaded her up, she went straight to the guns, unloaded, and returned for more. This saved time and allowed the guys to stay where they were needed.

She also made herself at home in the platoon. Reckless had a legendary appetite, happily munching on all sorts of things like scrambled eggs, pancakes, Hershey bars, C-rations candy, Coca-Cola, and even the occasional beer after a long day. If she spotted unattended food, it was fair game for her. And if the Marines ignored her too long, blankets, hats, and even poker chips sometimes disappeared into her mouth.

By spring 1953, Reckless was an integral part of the platoon. Then came the Battle of Outpost Vegas, one of the bloodiest battles in Marine Corps history during the Korean War. Artillery pounded the hills continuously, and ammo flew off the shelves as fast as it arrived. Every time someone crossed the rice paddies, they were exposed to enemy fire. But Reckless kept on trucking.

During just one day of the battle, she made a staggering 51 trips between the ammo supply point and the front line, hauling around 386 rounds of ammo and carrying over 9,000 pounds across roughly 35 miles of difficult terrain. Most of those trips she did without anyone leading her.

But that wasn’t all. Whenever wounded Marines needed help getting back down the hill, Reckless carried them too. After dropping them off safely, she would get loaded up with more ammo and head back into the fray.

She got injured twice during the battle, but she kept pushing through. The Marines never forgot her bravery, and she in turn formed a strong bond with them. During heavy shelling, they would throw their flak jackets over her to protect her from shrapnel, worrying about her safety just as much as their own. Sergeant Major James Bobbitt later recalled that seeing Reckless come down the trail with more ammo really lifted the Marines’ spirits.

After the war, Reckless came to the U.S. with the Marines and settled down at Camp Pendleton in California. She got promoted several times throughout her military career, eventually reaching Staff Sergeant, making her the highest-ranking horse ever in the U.S. military. She retired in 1960, had a few foals, and remained a cherished member of the Marine community until she passed away in 1968.

Today, you can find statues of Reckless all over the U.S., and years after her death, she was awarded the PDSA Dickin Medal, which is like the animal version of the Victoria Cross. But honestly, the best way to remember her isn’t just through the medals or monuments. It’s about picturing this small Korean mare who learned the trail so well that, when the Marines needed ammo, she just kept walking the same dangerous path again and again because that’s where her people needed her.
