Union Township was the site of the Battle of Connecticut Farms. On June 6, 1780, British troops, led by Hessian General Wilhelm von Knyphausen, boarded boats on Staten Island bound for Elizabeth, New Jersey. At midnight, 5,000 troops started to land. They expected the Continental Army to give little resistance, believing that they were tired of the war and were poorly fed and paid. They also expected the citizens of New Jersey to welcome them. They were wrong on both counts and were unable to make their way to and through the Hobart Gap.
