I'm planning to put together a page with some information about the Highlanders in western PA. I've been emailing with a fellow who is in a Highlanders reinactment group. He sent me this information:

Did you know that the first time that the kilt appeared in our area [Pittsburgh] was at the Battle of Grant's Hill on Sept.14th 1758 (where the County Courthouse,Frick Building and Kaufman's Dept.Store now stand?) Major James Grant of the 77th Regt.of Foote (Montgomery's Highlanders) was defeated there by French & Indians from Ft.Duquesne. We did a documentary titled "George Washington's First War:The Battles for Fort Duquesne" http://www.paladincom.com where this battle appears for the first time on film ever.

Check out the videos at the link he provided--I've added them to my Christmas list already!
