In September 1791 the western counties of Pennsylvania broke out in rebellion against a federal excise tax on the distillation of whiskey. After local and federal officials were attacked, President Washington and his advisors decided to send troops to pacify the region. It was further decided that militia troops, rather than regulars, would be sent. On August 7, 1794, under the provisions of the newly-enacted militia law, Secretary of War Henry Knox called upon the governors of Virginia, Maryland, New Jersey, and Pennsylvania for 12,950 troops as a test of the President's power to enforce the law. Numerous problems, both political and logistical, had to be overcome and by October, 1794 the militiamen were on the march. The New Jersey units marched from Trenton to Harrisburg, Pennsylvania. There they were reviewed by their Commander-in Chief, President George Washington, accompanied by Secretary of the Treasury and Revolutionary war veteran Alexander Hamilton. By the time troops reached Pittsburgh, the rebellion had subsided, and western Pennsylvania was quickly pacified. This first use of the Militia Law of 1792 set a precedence for the use of the militia to "execute the laws of the union, (and) suppress insurrections". New Jersey was the only state to immediately fulfill their levy of troops to the exact number required by the President. This proud tradition of service to state and nation is carried on today by the New Jersey Army and Air National Guard.
