Loyalhanna
Loyalhanna Creek flows north through the western Appalachian ridges to join the Conemaugh. Its name means “middle stream” in the language of the Lenape, who established a village at Layalhanning along its course. In 1758 the British built Fort Ligonier overlooking the creek as a base for General John Forbes's expedition against French-held Fort Duquesne. French and Indigenous forces attacked the post that October, but its defenders held it, and Forbes's army continued toward the Ohio.
