Amid an inferno of explosives on a deadly minefield in the Korean War, a four-legged Marine proved to be a heroic force of nature. She moved headstrong up and down steep, smoky terrain that no man could travail confidently. In a single day, this small Mongolian mare made fifty-one round-trips carrying nearly five tons of explosives to various gun sites. Sergeant Reckless was her name, and she was the horse renowned for carrying wounded soldiers on and off the battlefield and making solo trips across combat zones to deliver supplies. A widely celebrated national hero, Reckless was first featured in 1954 in the Saturday Evening Post and more recently in 1997 when LIFE magazine published an edition lauding history’s one hundred all-time heroes. Equine enthusiast Robin Hutton learned about Sergeant Reckless and spearheaded the effort to commission a monument at the National Museum of the Marine Corps in Triangle (Quantico), VA. In July of 2013, the statue was unveiled. A second monument is planned for Camp Pendleton, where Reckless lived out her days and is buried.
