Battle Pass, formerly known as Flatbush Pass or Valley Grove or The Porte, is a historic hill pass that played a significant part in the 1776 Battle of Long Island, and that is currently part of Prospect Park in Brooklyn.
Flatbush Pass went through Heights of Guan along the Native American trail Mechawanienck that preceded Kings Highway (later this section became Flatbush Road), and was at the border between the Towns of Brooklyn and Flatbush in Kings County under the Dongan Charter of November 12, 1685. Earlier, Governor Lovelace mentioned the pass in documents from 1670.[1][2]
