The Seven Years War (1756-63)

Manuscript and printed maps and views, correspondence and journals from the first global war


Point Levi, 1759

PLAN of the south side of the River St Laurence / from Point Levi to Point des Peres &c.


Pencil, pen, ink and watercolour on paper; laid down on linen | Scale: 1:7,200 | RCIN 732102

A map of the south side of the St Lawrence River from Point Levi to Point Peres, 30 June 1759. French and Indian War (1754-63). Oriented with south-south-east to top (compass rose). 

The old catalogue entry has identified the draughtsman as Patrick Mackellar, possibly based on the latter's signature on the map. This signature may have been an endorsement of the accuracy of the content of the map but, in this instance, the cartographic style does resemble that of Mackellar, who was Chief Engineer at Quebec. The identification of the surveyor, Captain Williamson, with Adam Williamson, is made on the basis that it is known that he was on the staff at Quebec and that he was wounded at Montmorency in August 1759. He had also been present in 1755 on Braddock's expedition to Fort Duquesne, where he was wounded in the battle on 9 July. Since Mackellar, too, was present on Braddock's expedition, the two men must have known each other for at least four years. Williamson, who became Lieutenant-General Sir Adam Williamson, Governor of Jamaica and St Domingo, was the son of Major-General George Williamson (1704-81) who commanded the artillery at the Siege of Louisbourg (1758) and at Quebec in 1759. Father and son were thus on active service together in this operation. George Williamson's ‘Disposition of Artillery at Visé’ in 1747 is at RCIN 730176. 

There is no overt indication, on the face of the map, that the date of the content relates to 30 June 1759; a faint note to this effect appears on the verso in what appears to be a contemporary hand.
