the higher ground was sparsely used. The area was heavily fortified prior to the Battle of Long Island in the American Revolutionary War. After British troops landed on Long Island and advanced towards Continental Army lines, General George Washington withdrew his troops here after heavy losses, but was able to make a skillful retreat across the East River to Manhattan without the loss of any troops or his remaining supplies. After the war, the 160-acre tract of land belonging to John Rapeljie, who was a Loyalist, was confiscated and sold to the Sands brothers, who tried to develop the part of the land on the palisade as a community they called "Olympia", but failed to make it come about, partly because of the difficulty of building there. They later sold part of their land to John Jackson, who created the Vinegar Hill community, much of which later became the Brooklyn Navy Yard. Development Brooklyn Heights began to develop once Robert Fulton's New York and Brooklyn Steam Ferry Boat Company began regularly scheduled steam ferry service in 1814, with the financial backing of Hezekiah Beers Pierrepont, one of the area's major landowners. Pierrepont had accumulated 60 acres of land, including 800 feet which directly overlooked the harbor, all of which he planned to sub-divide.

Pierrepont purchased and expanded Philip Livingston's gin distillery on the East River at what is now Joralemon Street, where he produced Anchor Gin. Wishing to sub-divide and develop his property, Pierrepont realized the need for regularly scheduled ferry service across the East River, and to this end he became a prominent investor in Robert Fulton's New York and Brooklyn Steam Ferry Boat Company, using his influence on Fulton's behalf; he eventually became a part owner and a director of the company. Fulton's ferry began running in 1814, and Brooklyn received a charter as a village from the state of New York in 1816, thanks to the influence of Pierrepont and other prominent landowners. The city then prepared for the establishment of a street grid, although there
