In the actual "stand up and point guns at each other from 10 feet" part of the battle, yes: badly defeated.
What you're describing is how the British were badly mauled by snipers on the way back home. But everybody knew that the Colonials couldn't win a revolution by sniping: they'd have to take on the British in real battles. That's where the likes of von Steuben were invaluable to us.
Yes and no---"run and gun" tactics more than pure sniping. But this was no mere aftermath; it constituted, I'd say, the majority of the battle. The actual set-piece line battle in Lexington was over in a flash, and in Concord, the British retreated from it---at least on the bridge. The set piece portion of the battles was over long before many of the militias from outside Middlesex county could get there.

I agree completely. To be fair, though, at Lexington and Concord, and probably at Bunker Hill as well, no one on our side was thinking about winning a revolution. Instead, we were defending our rights as "Englishmen." Hell, entire units of Connecticut militia simply cut out of the Charlestown line when their enlistments were up.
