An ancestor of mine fought in the Battle of Brooklyn. I've often wondered if any sites remained, or if they had been totally swallowed up the city.
It sounds like it would still be interesting to see, so despite my dislike of being in big cities, I'm adding it to my list of Revolutionary War sites I'd someday like to visit.
The main battle sites that still can be "enjoyed" today are in Greenwood cemetary and nearby Prospect Park. You can also pay homage to "The Maryland 400" who stood their ground repeatedly under a ferocious charge by the Brits and allowed most of Washington's army to escape capture or slaughter. Two hundred and sixty seven of those fine lads still lie in a mass grave in the vicinity of 8th Ave and Fourth St in Brooklyn.
