“Lady Louisa Lennox, with her Husband’s Regiment, 25th regiment of Foot,” by Giuseppe Chisea, 1771.
Lady Lennox (center, seated on drum) wears a fetching, pseudo-military, riding habit in imitation of her husband and his officers.
The drummer on the right wears a distinctive white bearskin cap. The soldier on the far right (behind the piper), and the officer second from the left, are members of the 25th’s ‘Highland Company.’ They wear small fur caps with red fronts and coats cut short so as to resemble jackets. Highland and picket companies were precursors to the later light companies, added to all infantry regiments (less Foot Guards) in 1771.
