The British efforts to reorganize the American colonies after 1763 impacted New Jersey as it did elsewhere. Whether the issue was new trade regulation or new plans for taxing the colonists, the New Jersey reaction was increasingly vocal. In 1774, opposition to the unpopular Tea Act took the form of the Greenwich Tea Burning, which mimicked the earlier events in Boston. New Jersey's central geographic location made the area a principal scene of military action with approximately 90 engagements taking place there. Major battles were fought at Trenton (1776), Princeton (1777), Monmouth (1778) and Springfield (1780). The Continental Army crossed New Jersey four times and made its winter encampment at Morristown twice.
