April 19, a very important day

Patriots Day. Marking April 19, 1775. When Americans took up arms against their king, and bled, at the crack of terrible dawn.

It's a holiday in Massachusetts and Maine, which was then part of Massachusetts. Should be a national holiday.

July 4 marks the day they published a piece of paper, telling the king to shove it. Important. Up until then it was a civil war. Americans who considered themselves Englishmen fighting British troops. After that, it was Americans fighting the British for their independence.

Patriots Day is first blood.
