For those familiar with the history of Louisbourg, there is some irony in the date of publication of these maps. Appearing in the May 1758 issue of Universal Magazine they highlight the 1745 seige. On May 29, 1758 the British Navy left Halifax for what would be the final battle over Louisbourg. By the time this issue reached subscribers, the battle was probably well underway.
Maps of the city and fort of Louisburg from 1745 and the Harbour of Louisburg with inset of Gabarus Bay during the 1758 siege by the British. The maps show British battle positions, details of the French fortifications and information on the outcome. Having such a detailed plan of the Fortress was no doubt of great use to the British as Louisbourg fell to them for the final time in 1758.
