From Bearing Arms:

“While the Declaration of Independence didn’t happen for another 15 months, the Revolutionary War actually began at Lexington Commons and the Concord North Bridge in the Spring of 1775, and it can honestly be said Americans have been fighting hard and shedding blood ever since to defend not just their natural right to be free from tyranny, but to protect and perpetuate what was and remains the uniquely American concept of freedom and liberty.
