Colonel Samuel Hay

Samuel Hay was a Pennsylvania officer whose Continental service brought him to the encampment near the Paoli Tavern in Chester County in September 1777, where he survived one of the most violent nighttime assaults of the Revolutionary War and subsequently committed his experience to paper in letters that became essential documents of the battle's history. He came from the community of Pennsylvania men — many of them Scots-Irish in background, many of them from the interior counties — who formed the reliable core of Pennsylvania's Continental regiments throughout the war, soldiers whose commitment to the cause survived repeated setbacks and the chronic hardships of Continental service.

Hay's regiment was in Wayne's division when Major General Charles Grey's force attacked the American camp on the night of September 20-21, 1777. He survived the assault and in the days that followed wrote detailed letters describing what he had seen. His accounts were not the report of a commander assessing the military situation but the testimony of a participant describing human experience: the men he found in the aftermath, the nature of their wounds, the evidence that some had been killed while attempting to surrender or had been bayoneted after they were already down. These details — the bodies of men found with bayonet wounds that appeared to be administered after resistance had ceased, the accounts of soldiers who claimed to have been refused quarter — formed the evidentiary foundation of the "massacre" narrative that patriot propagandists and newspapers developed around the battle. Hay's letters circulated and were quoted, helping to transform a military defeat into a grievance that stoked patriot outrage and contributed to the war's emotional intensification.

The historical significance of Hay's correspondence extended beyond its immediate propagandistic use. His letters, preserved in the archive of Pennsylvania's revolutionary-era records, became primary sources for historians attempting to reconstruct what actually happened at Paoli — to distinguish documented fact from embellishment, to understand the battle's scale and character, and to assess the competing British and American narratives. Whether the killing of surrendering men was systematic or incidental, widespread or isolated, the result of Grey's orders or the momentum of nighttime combat, remain questions that historians have debated using sources like Hay's accounts as their raw material. His willingness to write down what he saw preserved a perspective on the battle that might otherwise have been lost, making him, in his small way, a witness whose testimony shaped how one of the war's most notorious episodes was remembered.
