Cause

Loyalist troops and British-allied Native Americans conducted a series of raids against settlements along the northern and western branches of the Susquehanna River in North Central Pennsylvania, creating widespread fear among White frontier settlers and prompting Patriot militia commanders to call for evacuation.

Event

In June and July 1778, White settlers fled the frontier regions of North Central Pennsylvania in a mass evacuation known as the Big Runaway, relocating primarily to Fort Augusta near present-day Sunbury. Their abandoned homes and farms were burned under a scorched earth policy to deny resources to the enemy.

Consequence

Some settlers returned shortly after, but renewed Loyalist and Native American raids in 1779 forced a second evacuation called the Little Runaway. These events prompted retaliatory campaigns by the Continental Army, most notably Sullivan's Expedition, which destroyed more than 40 Iroquois villages and killed thousands of non-combatants.
