The Story
Fort Allen, also known as Truby's Blockhouse, was built and commanded by Col. Christopher Truby to shelter the scattered settlers of Westmoreland County on the exposed western frontier. It stood through the turmoil of Dunmore's War in 1774, later Indian conflicts, and the Revolution, when frontier families lived under constant threat of raid. From here in 1774, eighty inhabitants led by Wendel Oury petitioned Governor John Penn for aid against a feared uprising.
Why it matters
Frontier blockhouses like Fort Allen were the fragile backbone of settler defense in western Pennsylvania, marking the violent edge where the Revolution met Native resistance.
The story behind this marker
AI contextThe era
In the 1770s, Westmoreland County sat on the exposed western edge of Pennsylvania, where colonial settlement pressed hard against lands long held by Native nations. This was contested country — claimed, crossed, and fought over — and the families who settled here did so knowing that safety was never guaranteed. Their world was one of scattered cabins, forest trails, and long distances between neighbors.
On such a frontier, the blockhouse was a defining institution. A sturdy timber structure, often the home or holding of a leading settler, it doubled as a place of refuge when danger threatened. When word of a raid spread, families would abandon their farms and crowd inside its walls until the threat passed. These strongpoints were the difference between survival and catastrophe.
The decade layered crisis upon crisis here: the frontier conflict known as Dunmore's War in 1774, later clashes with Native nations, and then the Revolution itself. For the people of this county, these were not separate wars so much as one long ordeal of living at the edge.
People & events
Fort Allen was built and commanded by Colonel Christopher Truby, and it was known to locals simply as Truby's Blockhouse — a name that tells you it was as much a neighborhood refuge as a military post. It stood a short distance south of where the marker now sits, guarding the settlers scattered across this vulnerable stretch of country.
The inscription anchors the fort to a specific moment of fear. In 1774, as tensions on the frontier boiled toward Dunmore's War, eighty inhabitants of Westmoreland County put their names to a petition — led by Wendel Oury — asking Governor John Penn for help against a threatened uprising. That petition, sent from this very place, captures the frontier settler's predicament in a single act: too exposed to defend themselves, too far from the seats of power to be sure of aid.
Truby himself is remembered as an officer of the Revolution, and his blockhouse served through Dunmore's War, later Indian conflicts, and the Revolution. It was, in other words, a fixed point of safety across more than a decade of danger — the place people knew to run to when the frontier turned violent.
Its place in the American story
The story of American independence is usually told from east to west, from the cities and the great battles. But the nation also had a western frontier, and its fate mattered enormously to the country that would emerge. Whoever controlled the trans-Appalachian country — and whoever the Native nations there chose to side with — would help decide how far and how fast the young United States could grow.
Blockhouses like Fort Allen were the fragile backbone of that frontier. They were not glamorous, but they held communities together through years when the alternative was abandonment. The petition sent from here shows another enduring American pattern: ordinary citizens on the margins appealing to distant government for protection, and staking their claim to be heard.
The marker's mingling of Dunmore's War and the Revolution is historically honest. Out here, the line between colonial-era frontier conflict and the war for independence blurred, and the same families, the same forts, and the same fears carried across from one to the next.
If you visit
The blockhouse itself is long gone, so let the marker do its work as a pointer: the fort stood about 150 yards to the south. Look that way and picture a solid timber structure rising above the clearing, with families streaming toward it when alarm spread through the county.
What gives this site its character is the sheer span of history packed into one spot — a single blockhouse that saw a frontier war, later Native conflicts, and the Revolution. Standing here, you're at a place that endured through more than a decade of the region's most dangerous years.
For a road trip through western Pennsylvania's frontier past, Fort Allen is a rewarding stop precisely because it asks you to use your imagination. There's no fortress to tour, but there is a real and human story — of a colonel, his neighbors, and a petition of eighty frightened settlers — waiting to be read into the quiet Westmoreland countryside.

Col. William Crawford
Connellsville, PA · est. 1966
William Crawford was a frontier soldier and surveyor who settled near the Youghiogheny River after 1766, serving as George Washington's western land agent at a time when Virginia and Pennsylvania families were pushing across the Appalachians. During the Revolution he took up arms on the frontier, leading a 1782 expedition against Native villages along the Sandusky River in Ohio. The campaign ended in disaster: Crawford was captured and put to death, a killing that became notorious in the bitter borderland warfare of the era.
Colonel William Crawford - PLAQUE
Connellsville, PA · est. 1918
Born in Virginia in 1732, William Crawford was a pioneer surveyor and friend of George Washington who built his cabin at Stewart's Crossing on the Youghiogheny in 1765. He first came west with Forbes's 1758 campaign, crossed the Delaware with Washington in 1777, and shared the victory at Trenton. Leading the Sandusky Expedition against Native towns in 1782, he was captured and burned at the stake in Ohio — one of the frontier war's most infamous deaths.
Simon Girty (1741-1818)
Pittsburgh, PA · est. 2017
Born near Harrisburg, Simon Girty was captured and adopted by the Seneca as a teenager in 1756, and he came to move fluidly between Native and colonial worlds. He worked as an interpreter at Fort Pitt before defecting to the British in 1778, after which he advised and accompanied Native war parties in raids on frontier settlements during the Revolution. Reviled by many American settlers, he remains a deeply contested figure and is buried in Canada.
Fort Allen
Hempfield Township, PA · est. 1946
A little to the south once stood a fortified post raised in 1774 by Pennsylvania German pioneers of the Brush Creek and Harrold's settlements. In an era of frontier violence, such a stockade offered ordinary farm families a place to shelter during Dunmore's War and the American Revolution. It was a small but vital node in the network of refuges that let settlement cling to this exposed edge of colonial Pennsylvania.
