I recently visited the Fortress of Louisbourg on Cape Breton Island. I hope to put together a blog post once the photos get organized.
This has me interested in the Osprey book about the siege. It is available as a Kindle book. Are the maps of the fortress itself very good? If so I'll look for a hard copy. If they aren't wonderful, I could get the e-book with a click. Maps and such on e-books tend not to show up all that well.
If anyone has the book, please let me know what you think of the fortress maps.
