This is a Book of History. This book describes that The site now occupied by the two cities of New York and Brooklyn, and over which they continue to spread, is pre-eminently "Revolutionary soil". Very few of our historic places are more closely associated with the actual scenes of that struggle. As at Boston in 1775, so here in 1776, we had the war at our doors and all about us. In what is now the heart of Brooklyn Revolutionary soldiers lay encamped for months, and in the heat of a trying summer surrounded themselves with lines of works. What have since been converted into spots of rare beauty—Greenwood Cemetery and Prospect Park—became, with the ground in their vicinity, a battle-field. New York, which was then taking its place as the most flourishing city on the continent, was transformed by the emergency into a fortified military base.
