Uniform study of a soldier of the Westminster Middlesex Militia, with blue facings, 1780 (c).

The Militia Act of 1757 transformed part-time militia into a better-trained and better-equipped national force, organised by county.

Sir John Osborn (1743-1814) was commissioned as Lieutenant Colonel of the Bedfordshire Militia on 29 November 1779, and apparently acquired this work soon after. This was at a time when the ongoing war with America, in which his brother George fought, reinforced the importance of the Militia as an institution in Britain.
