    Fort Augusta, built in 1756        

Fort Augusta was Pennsylvania’s stronghold in the upper Susquehanna Valley from the days of the French and Indian War to the close of the American Revolution.  This site, now within the limits of the City of Sunbury, is an area the Indians called “Shamokin.”  First constructed as part of the British defense against the raids of the French and Indians from the upper Allegheny region, it was later used as an American fortress to aid in the protection of the settlers of the upper Susquehanna from Britain’s Indian allies to the north.  It was named for the mother of King George III.

Fort Augusta was built with: 

  • logs, upright in the part facing the river, lengthwise in the rear, and was about two hundred feet square. 

  • the main wall of the fort  faced or “revetted” to about half its height by a dry ditch or moat. 

  • a triangular bastion in each corner which permitted a crossfire that covered the entire extent of the wall. 

  • the main structure of the fort enclosing officers’ and soldiers’ quarters, a
    magazine, and a well, the last two of which are still preserved.

  • the fort  further protected by an outer stockade, which was flanked by four blockhouses, two on each side.  The blockhouses in turn were connected by a stockade, forming a “covered way” to the river. 

  • it is said to have had sixteen mounted cannons, two of which are still preserved in the Museum.  

Fort Augusta was never forced to endure a siege.  Its strength and position discouraged attack.  Its existence limited the effectiveness of the French raids and threatened French power in northwestern Pennsylvania.  It held the Susquehanna Valley for Britain.

During the Revolutionary War, Fort Augusta was the military headquarters of the American forces in the upper Susquehanna Valley.  The activities of the Northumberland County Militia, the sending of troops to serve in Washington’s army, and the support and protection of smaller posts throughout the valley were all directed from the Fort, where Colonel Samuel Hunter, the last commandant, resided.

  After the War, 

  • the Fort gradually deteriorated

  • Colonel Hunter was allowed to retain the Commandant’s Quarters as his property.  

  • his descendants continued to live there until 1848, when the log house burned.  

  • the present Hunter House was completed in 1852 by the Colonel’s grandson, Captain Samuel Hunter.  

  • both men are buried in the Hunter-Grant Cemetery across the street, behind 
    The Hunter House.  

In 1930, the Commonwealth of Pennsylvania purchased the land on which the well and magazine are located, and, in 1931, acquired the larger tract, which included The Hunter House.  This combined Fort Augusta property is now the headquarters of the Northumberland County Historical Society.
