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.
It's interesting to look at maps that were drawn at a time of significant events. Such is the case with this Saint-Malo map. Published in June 1758 while the final seige of Louisbourg was underway, it would be to Saint-Malo that many Acadian exiles would be sent later in 1758 and 1759.
