On Purple Heart Day: 7 facts you didn't know about the Purple Heart

The Purple Heart was established in 1782 — and has been awarded to an estimated 1.8 million service members, civilians, and courageous animals since. Here are seven facts you might not have known about the Purple Heart.
1. Army Sgt. Stubby, a dog who was smuggled to Europe by members of the 102nd Infantry Regiment, earned the Purple Heart twice during World War I -- once for being wounded in a gas attack and once for being wounded by a grenade.
2. Audie Murphy received the Purple Heart three times during World War II. He also received every combat award for valor available from the Army -- including the Medal of Honor -- as well as French and Belgian awards for heroism.
3. One of the most famous civilians to earn the Purple Heart was Ernie Pyle, a war correspondent who covered World War II from the trenches of Europe before being killed in the Battle of Okinawa.
