Pennsylvania

Mercer, PA · est. 1917

Hugh Mercer, a Scottish-born physician turned soldier, first crossed the mountains as an officer in General Forbes's 1758 expedition against Fort Duquesne and later commanded at Fort Pitt. When the Revolution came he took up arms again, rising to brigadier general in the Continental Army. He fell mortally wounded at the Battle of Princeton in 1777, becoming one of the cause's celebrated martyrs.

Union Township, PA · est. 1948

In the bitter winter of 1778, with the Revolution raging on the frontier, General Edward Hand marched some 800 militia out of Fort Pitt intending to strike a British supply depot near present-day Cleveland. Weather and poor roads doomed the expedition before it reached its target, and the frustrated force instead fell upon a small Native settlement in the river fork below this spot, killing a man and an elderly woman before turning home. The dismal, aimless outcome earned the venture a mocking name that has clung to it ever since.

North Beaver Township, PA · est. 1948

By April 1773 the Christian Delaware of Friedensstadt, guided by the missionary John Heckewelder, abandoned their Beaver River town and resettled on the Muskingum River in what is now Ohio. There tragedy overtook them: on March 8, 1782, Pennsylvania militiamen murdered scores of these peaceful, unarmed converts at Gnadenhütten in one of the darkest atrocities of the Revolutionary frontier. The marker traces the thread from this quiet Pennsylvania mission to that infamous massacre.

Springfield Township, PA · est. 1949

William Penn founded Pennsylvania in 1681 as a Quaker commonwealth built on religious tolerance and self-government, an experiment that drew settlers of many faiths to the Delaware Valley. Within a century that colony became the setting where the Declaration of Independence and the Constitution of the United States were written. This state-line marker greets travelers with that founding heritage.
