Marker Inscription
On October 25, 1755, John Harris, founder of Harrisburg, and a party of 40 men, who came up the river to investigate the (John) Penns Creek Massacre, were ambushed by a party of Indians near the mouth of this creek, at the head of the Isle of Que, about one third of a mile south of this spot.

The Story
In the autumn of 1755, the Pennsylvania frontier along the Susquehanna erupted in violence as the French and Indian War spread east of the mountains. John Harris — the ferryman and trader whose settlement would grow into Harrisburg — led some forty men upriver to look into the raid on nearby settlers, only to be ambushed near the mouth of this creek at the head of the Isle of Que. The skirmish was one of many that convinced Pennsylvania's Quaker-led government it could no longer leave its backcountry undefended.
Why it matters
The ambush marks the moment the wider imperial war reached ordinary Pennsylvania settlers, spurring the string of frontier forts that would define the colony's mid-1750s defense.

Penns Creek Massacre - PLAQUE
Monroe Township, PA · est. 1919
In October 1755, along the banks of Penn's Creek, frontier families were attacked and roughly two dozen settlers were killed, wounded, or carried off into captivity. The raid came just months after General Edward Braddock's disastrous defeat near the Monongahela, which shattered British prestige and emboldened France's Native allies. It is remembered as the first such outbreak of frontier violence within Pennsylvania during the French and Indian War.
Penns Creek Massacre
Monroe Township, PA · est. 1947
On October 16, 1755, a war party struck the scattered settlers along Penns Creek, killing, wounding, or carrying off some two dozen people. Coming just weeks after General Braddock's catastrophic defeat near Fort Duquesne, it was the first such attack to fall on the Pennsylvania frontier as the French and Indian War spilled eastward. The raid shattered the colony's fragile peace and sent shockwaves through the backcountry.
Sunbury
Shamokin Dam, PA · est. 1948
Sunbury was laid out in 1772 as the seat of newly formed Northumberland County, planted on the site of Shamokin, an important Native American town at the forks of the Susquehanna. Sixteen years earlier, during the French and Indian War, colonial authorities had built Fort Augusta here to guard the frontier. The spot's command of the river made it a lasting hub of travel, trade, and industry.
Sunbury
Sunbury, PA · est. 1947
Laid out in 1772 as the seat of newly formed Northumberland County, Sunbury rose on the site of Shamokin, a major Native town at the forks of the Susquehanna. Surveyors John Lukens and William Maclay platted the town where Fort Augusta had stood since 1756, guarding the frontier, and the community grew into a hub of travel, trade, and industry before its incorporation as a borough in 1797.
