The Baylor Massacre took place in 1778 in River Vale, resulting in severe losses for the Continentals.
Local militia retook Hackensack and the rest of Bergen County.
Bergen County saw skirmishes throughout the war as armies from both sides maneuvered across the countryside.
Located in the northeastern corner of New Jersey and its Gateway Region, Bergen County is part of the New York City Metropolitan Area and is directly across the Hudson River from Manhattan, to which it is connected by the George Washington Bridge.
Bergen County is divided into 70 municipalities, but has no large cities.
After abandoning the defenses in Fort Lee and leaving behind considerable supplies, the Continental forces staged a hasty retreat through present-day Englewood, Teaneck, and Bergenfield, and across the Hackensack River at New Bridge Landing, one of the few sites where the river was crossed by a bridge.
They destroyed the bridge to delay the British assault on Washington's headquarters in village of Hackensack.
It is believed that the county is named for one of the earliest settlements, Bergen, in modern-day Hudson County.
However, the origin of the township's name is debated.
In 1894, state law was changed to allow easy formation of municipalities with the Borough form of government.
This led to the "boroughitis" phenomenon, in which many new municipalities were created in a span of a few years.
