Perkiomen Township, Montgomery County, Pennsylvania
Marker Inscription
THIS STONE MARKS THE CAMP OF WASHINGTON'S ARMY, PENNYPACKER MILLS. SEPT. 26-29 OCT. 5-8, 1777 HISTORICAL SOCIETY OF MONTGOMERY CO., PA. OCT 8, 1897 -- WASHINGTON'S HEADQUARTERS AT THE HOUSE OF SAMUEL PENNYPACKER 377 YARDS NORTHEAST OF THIS STONE.
The Story
During the tense weeks around the Battle of Germantown in the fall of 1777, George Washington marched his army through the Pennsylvania countryside, camping at Pennypacker Mills in late September and again in early October. Washington made his headquarters in the house of Samuel Pennypacker while the Continental Army rested and regrouped nearby. This stone, placed by the Historical Society of Montgomery County in 1897, marks the ground where that encampment stood.
Why it matters
It preserves a working chapter of the Philadelphia campaign, showing how Washington's army moved, sheltered, and recovered between battles in the struggle for independence.
The story behind this marker
AI contextThe era
The fall of 1777 was a tense, exhausting season for George Washington's Continental Army. The British had seized Philadelphia, and Washington's men spent those weeks marching, camping, and maneuvering through the Pennsylvania countryside — fighting when they could, resting and regrouping when they had to.
A war is not only battles. Between the fighting came the unglamorous, essential work of moving thousands of men, finding ground to camp on, and giving a bruised army time to recover. This stone marks one of those working chapters: the ground at Pennypacker Mills where Washington's army camped, once in late September and again in early October of 1777, straddling the days of the Battle of Germantown.
The monument itself belongs to a later era. It was placed in 1897 by the Historical Society of Montgomery County — a generation reaching back to honor the ground where the founding army had passed more than a century before.
People & events
The central figure is Washington himself, who according to the stone made his headquarters in the house of Samuel Pennypacker, a short distance from where the marker stands. A commander's headquarters was the nerve center of the army — where orders were written, councils held, and the next moves decided.
The camp dates the stone records — late September, then early October 1777 — bracket the Battle of Germantown. Standing at Pennypacker Mills, you're looking at the ground where the army gathered itself before that fight and returned to afterward, the quiet bookends around a hard day.
The second figure worth noting is the one who lent his house and, indirectly, his name to the site: the Pennypacker family, whose home became Washington's headquarters. When a general commandeered a private house, an ordinary family's home was pulled straight into the machinery of a revolution — a reminder of how the war reached into the lives of the people whose land it crossed.
Its place in the American story
Encampment sites like this one preserve a truth easy to forget: armies spend far more time marching and camping than fighting. The survival of the Continental Army through such movements — feeding it, sheltering it, holding it together between battles — was itself a kind of victory, and it is the story this stone protects.
The Philadelphia campaign was one of the pivotal contests of the war, fought over the young nation's own capital. The ground where Washington sheltered his army during those weeks is part of the connective tissue that links the campaign's famous battles into a single, grinding effort.
There's a second layer of meaning here, too. The monument was raised in 1897, long after the war, by people determined that this ground not be forgotten. It stands as evidence of how later generations chose to remember the Revolution and to mark the everyday places, not just the battlefields, where it was won.
If you visit
Look first for the stone itself, and read it as the two-part record it is: the camp dates on one face, and the note that Washington's headquarters stood a stated distance to the northeast. That second line turns the whole landscape into part of the exhibit — the monument points you toward the ground where the general actually lodged.
Then let your eye take in the surrounding countryside. This is gentle, rolling Pennsylvania farmland, and picturing thousands of tired soldiers camped across it is the real reward of the visit. The quiet of the place today is a striking contrast to the crowded, anxious army that once filled it.
This is an easy and rewarding stop on a tour of the Philadelphia campaign, pairing naturally with the region's better-known battle sites. Remember that the monument dates to 1897, so you're standing at the meeting point of two histories at once — the Revolution it commemorates, and the later generation that cared enough to mark it.

Revolutionary War Soldier's Grave Marker
Perkiomen Township, PA
In the autumn of 1777, George Washington's army fought a costly battle at Germantown just outside British-held Philadelphia. Among the wounded was Major Edward Sherburne of New Hampshire, an aide to General John Sullivan, who was struck down on October 4 and died the following evening. This grave marker remembers a young staff officer whose service ended far from home in the war's brutal Philadelphia campaign.
Pennypacker's Mill and Mansion
Perkiomen Township, PA · est. 1946
This Montgomery County house served as George Washington's headquarters in the autumn of 1777, during the fraught campaign around Philadelphia in the Revolutionary War. Generations later it became the beloved home of Samuel W. Pennypacker, who served as governor of Pennsylvania in the early 1900s and died here in 1916. Few homes can claim to have sheltered both a founding general and a modern governor beneath one roof.
Muhlenberg House
Trappe, PA · est. 1960
This Trappe house was the home of Henry Melchior Muhlenberg, the German-born pastor often called the organizer of the Lutheran church in America, who lived here from 1776 until his death in 1787. His son Peter Muhlenberg — famous for reportedly shedding his clerical robes to reveal a Continental uniform — went on to become a general in the Revolution and later lived in the same house. Under one roof the family joined the story of American religion to the story of American independence.
Frederick A. C. Muhlenberg (1750-1801)
Trappe, PA · est. 2008
Frederick Muhlenberg came of age as the American republic was being invented on paper. A Lutheran minister turned statesman, he sat in the Continental Congress, led Pennsylvania's assembly, and presided over the state convention that ratified the new federal Constitution in 1787. When the first Congress convened in 1789 he was chosen Speaker of the House, and his was the first signature on the Bill of Rights. He kept his home here in Trappe through those founding years.
