The Battle of Iron Works Hill, also known as the Battle of Mount Holly, was a series of minor skirmishes that took place on December 22 and 23, 1776, during the American Revolutionary War. The fighting took place in Mount Holly, New Jersey, between an American force mostly composed of colonial militia under Colonel Samuel Griffin and a force of 2,000 Hessians and British regulars under Carl von Donop.
While the American force of 600 was eventually forced from their positions by the larger Hessian force, the action prevented von Donop from being in his assigned base at Bordentown, New Jersey, and in a position to assist Johann Rall's brigade in Trenton, New Jersey, when it was attacked and defeated by George Washington after his troops crossed the Delaware on the night of December 25–26, 1776.
In July 1776 forces of Great Britain under the command of General William Howe landed on Staten Island. Over the next several months, Howe's forces, which were British Army regulars and auxiliary German troops usually referred to as Hessian, chased George Washington's Continental Army out of New York City and across New Jersey. Washington's army, which was shrinking in size due to expiring enlistments, and desertions due to poor morale, took refuge in Pennsylvania on the western shore of the Delaware River in November, removing all the available watercraft to deny the British any opportunity to cross the wide river.
General Howe established a chain of outposts across New Jersey, and ordered his troops into winter quarters. The southernmost outposts were located at Trenton and Bordentown. The Trenton outpost was manned by about 1,500 men of a Hessian brigade under the command of Johann Rall, and the Bordentown outpost was manned by Hessians and the British 42nd Regiment contingents, about 2,000 troops in all, under the command of the Hessian Colonel Carl von Donop. Bordentown itself was not large enough to house all of von Donop's force. While he had hoped to quarter some troops even further south at Burlington, where there was strong Loyalist support, floating gun batteries from the Pennsylvania Navy threatened the town, and Donop, rather than expose Loyalist allies to their fire, was forced to scatter his troops throughout the surrounding countryside.
As the troops of von Donop and Rall occupied the last outposts, they were often exposed to the actions of rebel raids and the actions of Patriot militia forces that either arose spontaneously or were recruited by Army regulars. These actions frayed the nerves of the troops, as the uncertainty of when and where such attacks would take place, and by what size force, put the men and their commanders on edge, leading them to jump up to investigate every rumored movement. Rall went so far as to order his men to sleep "fully dressed like [they were] on watch."
The American Revolutionary War (1775–1783) grew from colonial resistance to British taxation without parliamentary representation — a dispute that radicalized through the Stamp Act (1765), the Townshend Acts (1767), and the Boston Massacre (1770). Fighting began at Lexington and Concord in April 1775; the Continental Congress declared independence on July 4, 1776. The Continental Army under George Washington faced severe shortages of supplies and troops, enduring the brutal winter at Valley Forge (1777–1778) before French alliance and French financing turned the military balance. Major engagements included Bunker Hill (1775), Trenton (1776), Saratoga (1777) — which secured French intervention — and Yorktown (1781), where British General Cornwallis surrendered to Washington. An estimated 25,000 American soldiers died in service, from combat, disease, and captivity. The Treaty of Paris (1783) recognized American independence and ceded British territory east of the Mississippi, though it left unresolved questions about Indigenous land rights and the status of Loyalists.
