What national holiday do we celebrate on August 7th?
Answer: Purple Heart Day
As mentioned in the newsletter via History:
"On this day in 1782, in Newburgh, New York, General George Washington, the commander in chief of the Continental Army, creates the “Badge for Military Merit,” a decoration consisting of a purple, heart-shaped piece of silk, edged with a narrow binding of silver, with the word Merit stitched across the face in silver. The badge was to be presented to soldiers for “any singularly meritorious action” and permitted its wearer to pass guards and sentinels without challenge. The honoree’s name and regiment were also to be inscribed in a “Book of Merit.”
With that said, no further explanation is necessary. Purple Heart Day on August 7th commemorates the creation of the oldest military award for merit and honors the recipients who have received the decoration since the inception in the late 1700s.
