The American Revolution sharply divided families and towns on Long Island. Washington's defeat at the Battle of Long Island in August 1776 started seven years of British occupation. Patriot sympathizers were subject to loyalty oaths, theft of property, and the quartering of soldiers in their homes. Some fought back with acts of sabotage and espionage. Dr. Joanne S. Grasso explores the story of an island at war.
The SHWHM preserves and promotes the Sag Harbor culture through historical objects, hosting exhibits and events.
