When a group of United States Marines fighting in the Korean War found a bedraggled mare, they wondered if she could be trained as a packhorse. They had no idea that this skinny, underfed horse had one of the biggest and bravest hearts they would ever know. She also had an incredibly large appetite. Soon, the horse they named Reckless showed herself more than willing to carry heavy ammunition that was far too difficult for the soldiers to haul up steep mountains. As cannons thundered and shells flew through the air, Reckless marched boldly into battle again and again. She quickly became a beloved companion to the troops, sharing their tents and even eating their scrambled eggs. Her incredible bravery under fire earned her the respect of everyone around her. Discover the true, inspiring story of how a hungry little horse transformed into a heroic Marine, becoming the only animal to ever officially hold military rank and receive two Purple Hearts for her service.
