It sounds like Pensacola Florida might be the base of operations for the Canadian crew. Not entirely sure if it’s the whole contingent but it sounds like at least the army engineers and construction crews might be. Pensacola is pretty close to the whole area but it would mean trucking in supplies. Since New Orleans doesn’t really have a working port at the moment, it makes sense.
Oh, and the return travel for the army personel will be either by air or land. ;) My father-in-law sent me an email this morning and it sounds like a lot of his men won’t be making any plans to travel on a boat any time soon, if ever again. :)
