Etching and engraving; printed on paper; hand-coloured | Scale: not stated | RCIN 731061.b

A plan of the encampments and march route of the British army, 1755. French and Indian War (1754-63). No orientation. 

This diagram shows the order of march; the following officers are named: Sir Peter Halkett, Colonel (1703-9 July 1755) commanding the 44th Regiment of Foot, Captain Dagworthy (Maryland Company), Captains Gates, Rutherford, and Dobbs (Independent), Captains Waggoner, Hogg, Cock, and Stephens (Virginia Rangers), Colonel Dunbar.

One of six plans of Braddock's marches, camps, and campaign in 1755 (see RCINs 731061.a-f). These maps are closely based on the manuscript maps of the same titles in 'A Journal of the Expedition to North America in 1755, under General Braddock'; BL King's MS 212. The Fort Cumberland referred to in this set of plans was in Maryland (39°39'03"N 78°45'55"W). It was the westernmost outpost of British territory in North America and was the point of departure for General Edward Braddock's (bap.2 February 1695-13 July 1755) march to Fort Duquesne (40°26'29"N 80°00'39"W).
