Actually, they are still sore about the Lexington event! 
What happened when the Brits try to take away our guns the first time at Lexington 0n 19 April, 1775?
Thomas Jefferson, “I enclose you a list of the killed, wounded, and captives of the enemy from the commencement of hostilities at Lexington in April, 1775, until November, 1777, since which there has been no event of any consequence …
I think that upon the whole it has been about one half the number lost by them, in some instances more, but in others less. This difference is ascribed to our superiority in taking aim when we fire; every soldier in our army having been intimate with his gun from his infancy.” - Thomas Jefferson, letter to Giovanni Fabbroni, June 8, 1778
