Captain Thomas Cresap (1703-1790) - PLAQUE
Lower Windsor Township, York County, Pennsylvania
Marker Inscription
A Marylander. Settled on these Indian lands of Conejohela in 1730 and held them for Lord Baltimore against the Penn Proprietors until 1736, when in the Border War he was burned out of his log house or fort near this marker toward the river - on his plantation "Pleasant Garden" - and carried prisoner to Philadelphia.

The Story
When Thomas Cresap settled here in 1730, the border between Pennsylvania and Maryland was undrawn and hotly contested, and he claimed these lands for Lord Baltimore against the heirs of William Penn. His stubborn defense made him a flashpoint of "Cresap's War," the frontier feud over the disputed boundary. In 1736 Pennsylvania forces burned him out of his fortified log house and hauled him off a prisoner to Philadelphia.
Why it matters
This border war helped drive the surveying of the Mason-Dixon Line, one of the most consequential boundaries in American history.
The story behind this marker
AI contextThe era
In 1730, the line between Pennsylvania and Maryland was not a line at all — it was a quarrel. The two colonies' charters described overlapping claims to the same country, and along the lower Susquehanna, where this marker stands in York County, rival proprietors both insisted the land and its settlers were theirs.
Into that undrawn border came settlers who had to choose, or be claimed by, one side or the other. The fertile lands here at Conejohela made the stakes real: every farm planted was, in effect, a claim staked for one colony against the other.
This was frontier in the jurisdictional sense — not a wilderness so much as a contested seam between two colonial governments, where the ordinary business of settling land became an act loaded with political meaning and, soon enough, with the threat of force.
People & events
Thomas Cresap, a Marylander, settled on these Indian lands of Conejohela in 1730 and held them for Lord Baltimore against the Penn proprietors. His plantation here bore the hopeful name "Pleasant Garden," but the years that followed were anything but.
Cresap's stubborn defense of his ground made him the human flashpoint of the border war between the colonies — the conflict remembered as Cresap's War, or the Conojocular War, fought over this disputed boundary. He held his position for six uneasy years.
The end came in 1736. Pennsylvania forces burned him out of his fortified log house near this marker, down toward the river, and carried him off a prisoner to Philadelphia. A single settler's homestead had become a battlefield in a war between two colonies, and when it fell, it fell in flames.
Its place in the American story
It is easy to imagine colonial America as a set of tidy provinces with settled edges. Cresap's story is a bracing correction: the borders we now take for granted were, in their time, genuinely up for grabs, and men fought and burned and were imprisoned over them.
The boundary dispute that swept up Cresap helped drive one of the most consequential acts of surveying in American history. The need to finally fix the contested line between these colonies led to the drawing of the Mason–Dixon Line — a boundary that would take on meanings its surveyors never imagined, eventually standing in the national imagination as the divide between North and South.
So a feud over fields at Conejohela connects to a line that helped define the geography of the young nation. The violence here was local and personal; its resolution reached into the shape of America itself.
If you visit
Picture the geography as you stand here. The marker points toward the river, where Cresap's fortified house once stood on his plantation — a reminder that this peaceful riverside ground was worth fighting a small war over.
Let the name "Pleasant Garden" sit with you against what happened to it. The contrast between that hopeful name and the log house going up in flames is the whole drama of the place in miniature.
This is a fine stop on a drive through York County's river country, especially if you enjoy the kind of history that complicates the map. You won't find a fort to tour, but you can look out over the Susquehanna and appreciate that the calm border between two states was once a line men were willing to burn and imprison each other to decide.

Marcus A. Reno
New Cumberland, PA · est. 2001
Marcus A. Reno, whose farm lay near here, is remembered for one of the most scrutinized moments in American military history. As a major in the 7th U.S. Cavalry, he led a battalion at the Battle of the Little Bighorn in June 1876; while George Armstrong Custer and the men with him were annihilated, Reno and most of his command dug in and survived. Earlier, during the Civil War, he had helped defend this stretch of Pennsylvania against Confederate incursions.
Cresap's Fort
Lower Windsor Township, PA · est. 1960
About 1730 the frontiersman Thomas Cresap settled along the Susquehanna on land that Maryland's Lord Baltimore claimed against Pennsylvania, making his fortified home a flashpoint in the bitter boundary dispute between the two colonies. In 1736 Penn's agents forcibly evicted him and burned his "fort," and Cresap moved west into Maryland, where he remained a restless figure in frontier affairs until his death around 1790. His stand gave the border quarrel one of its most colorful episodes.
Washington Boro Archaeological Sites
Manor Township, PA · est. 2007
Along a bend of the lower Susquehanna River lies one of the densest clusters of archaeological sites in Pennsylvania, holding traces of human presence stretching back some 11,000 years — from fleeting hunting camps to sprawling palisaded villages. Its most powerful inhabitants were the Susquehannocks, an Iroquoian-speaking people who dominated the regional fur trade with European colonists through much of the 1600s. By 1675, warfare with rival nations and devastating epidemics had shattered their power. Generations of excavation here have reshaped how scholars understand Native lifeways in the mid-Atlantic.
Martin Chartier - PLAQUE
Manor Township, PA · est. 1925
Martin Chartier was a French adventurer from Canada who had served at La Salle's Fort St. Louis in the Illinois country before leading a band of Shawnee eastward, first to Maryland and then, by 1697, to the Susquehanna at Pequea Creek. Settling on a tract granted him by William Penn, he became one of early Pennsylvania's most important Indian traders and interpreters, and an agent in Penn's treaties with the Susquehanna nations. His son Peter, born of his Shawnee wife, carried on the trade after him.
