Fort at Number 4

Fort at Number 4. It was a pivotal colonial stockade fortification constructed in the 1740s on the northern frontier of the Province of New Hampshire. Strategically located on the Connecticut River in present-day Charlestown, New Hampshire, it served as the northernmost British settlement in the region for over a decade. The fort played a crucial role during the French and Indian War, notably enduring a significant Siege of Fort at Number 4 in 1747, and later functioned as a staging ground for expeditions into New France.

History

The settlement, originally known as "Number 4" as it was the fourth township chartered by the Massachusetts Bay Colony west of the Connecticut River, was founded in the early 1740s by pioneers from Massachusetts and Connecticut. Its existence was immediately challenged by the geopolitical tensions of the War of the Austrian Succession, known in the colonies as King George's War. In April 1747, a combined force of French colonial forces and their Abenaki allies from Saint-François-du-Lac laid siege to the fort for three days but were ultimately repulsed by the determined garrison under Captain Phineas Stevens. This successful defense became a celebrated event in New England and bolstered the region's morale. During the French and Indian War, the fort was rebuilt and garrisoned by provincial troops from the New Hampshire Provincial Regiment and became a vital forward operating base for units like Rogers' Rangers, who launched raids against French positions like Fort Saint-Frédéric and settlements in Canada.

Construction and design

Built between 1744 and 1746, the fort was a classic example of a frontier stockade. Its primary defensive structure was a sturdy log palisade approximately 180 feet square, with blockhouses projecting from each corner to provide flanking fire along the walls. The main gate was heavily reinforced and faced south, away from the primary threat direction of the Connecticut River to the west. Within the walls stood essential structures including a guardhouse, a storehouse, and family dwellings, as it was designed to protect the entire community of settlers. The construction utilized local timber and followed design principles common to British Army frontier posts of the era, emphasizing protection against musket fire and small-scale assaults rather than artillery.

Military significance

The fort's location made it a critical strategic asset on the contested frontier between British America and New France. It served as a vital reconnaissance point and a barrier against raids from French Canada descending the Connecticut River corridor. Its successful defense in 1747 demonstrated the viability of British settlements in the upper valley and secured the region for further expansion. During the French and Indian War, it was a key logistical hub and muster point for British offensives, including the pivotal Crown Point Expedition of 1755 and the campaigns leading to the Battle of Quebec in 1759. The presence of Rogers' Rangers at the fort underscored its role in fostering the development of irregular warfare tactics that were influential throughout the conflict.

Later use and preservation

Following the Treaty of Paris (1763), the immediate military threat receded, and the fort was gradually abandoned as a garrison, with the surrounding community of Charlestown, New Hampshire growing into a permanent town. The original structures fell into disrepair and were eventually lost. In the 20th century, historical interest led to archaeological investigations and a full-scale reconstruction on the original site. Today, the Fort at Number 4 is operated as an open-air museum by the **Fort at Number 4 Association**, featuring reconstructed buildings and living history demonstrations. It is listed on the National Register of Historic Places and educates visitors on colonial frontier life, military history, and the complex interactions between European settlers and Indigenous peoples of the Americas.
