A map of the march of the British army from Fort Cumberland to the field of battle near the Monongahela River, 1755. French and Indian War (1754-63). Oriented with north-east to top (cardinal points).

The attribution to Patrick Mackellar is made on stylistic grounds. Mackellar was an engineer on this expedition and was severely wounded at the Battle of Monongahela on 9 July 1755. The extract from the journal shows that the route from Fort Cumberland (39°39'03"N 78°45'55"W) to the field of battle (shown by crossed swords east of Fort Duquesne) covered 113½ miles. Nineteen camp sites are marked and named along the route. The text is tabulated under the following headings: Names of the Encampments; Dist.s Miles; Work done to the Road; Quality of the Road; Quality of the Camp. The journey took twenty-nine days, ten of which were halt days.

The 'Mr Gist' referred to by Mackellar in the title was Christopher Gist, surveyor and guide to George Washington, who prepared the first official map of the British army's route and encampments. For a discussion of the mapping of this campaign see Baker (2011).
