History

The Middlebrook encampment was a seasonal encampment of the Continental Army during the American Revolutionary War near Martinsville that straddled the ridge of the First Watchung Mountains. Its position provided a natural fortress not only protecting the Continental Army, but also overlooking the plains towards New Brunswick where the British forces were stationed in 1777.

Tradition holds that it was at the Middlebrook encampment that the first official flag of the United States was unfurled, after a law to adopt a national flag had been passed by Congress on June 14, 1777. By special order of Congress, a Thirteen Star Flag is flown 24 hours a day at the Washington Camp Ground, part of the former Middlebrook encampment, in Bridgewater. Since 1889, the first hoisting of the flag is commemorated annually each July 4 with a changing of the flag, a reading of the United States Declaration of Independence, and the delivery of an historical address.
