The Purple Heart is awarded to US service men and women who are injured in combat. It is not something you want to receive, but it is a special tribute to those who are injured or killed in defense of their country.
The Purple Heart was created by George Washington at the end of the Revolution. It was restarted in honor of the soldiers injured or killed in World War I and remains a military honor today. The National Purple Heart Hall of Honor is located in New Windsor, NY, which is where the Army was stationed when Washington created the honor originally. The Hall of Honor shares the grounds with the New Windsor Cantonment, which is where the Army was stationed, and there is a part of it set up as a museum with artifacts from the Revolution, as well as some buildings from Revolutionary time.
My brother and I visited the Hall of Honor and Cantonment several weeks back. It's a bit of a somber place to visit, especially reading the stories of those who were lost and seeing what those who were injured had to endure, but it's an excellent place to visit if you are into history, as I am.
