Rev. William Ten Eyck Adams was pastor of the Edgewood Reformed Church in the Borough Park neighborhood of Brooklyn. The lantern slides in this collection originate from a 1901 lecture he delivered on the Battle of Long Island at churches and assemblies in Brooklyn.
The Battle of Long Island occurred on August 27, 1776 in what is now the borough of Brooklyn, N.Y. The battle was the largest of the American Revolutionary War. It resulted in a victory for the British army and the retreat of the Continental Army through Manhattan and New Jersey into Pennsylvania.
