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 traverse 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.

Hutton has now written the first-ever full biography of Sergeant Reckless, who earned two Purple Hearts for her heroic efforts. Hutton has spoken with the Marines who fought alongside Reckless and tells the complete and captivating tale of how a would-be Korean racehorse became one of the greatest Marine wartime heroes.

Sgt. Reckless brings the legend back to life more than half a century later.
