 There was going to be a Fontenoy reenactment this year but it got cancelled which is a shame. But we can still commemorate it. 

See here for the history of the regiment.

Originally titled Crawford's Highlanders or the Highland Regiment (mustered 1739) and numbered 43rd in the line, in 1748, on the disbanding of Oglethorpe's Regiment of Foot, they were renumbered 42nd (Wiki)
