It makes 0 sense that Hansen arrives on Enterprise in an Excelsior just like every other admiral, then takes command of some mysterious Galaxy-class ship.
Not really.
Excelsiors do seem like standard "flag ferries", explaining why Hanson would use one to visit Jouret - but as soon as he arrives to his apparently haphazardy assembled fighting force, he would do well to pick a ship optimally suited for his fighting plan. That happens a lot in naval history: admirals hop onto fast ships for better situational awareness, or strong ships for combat persistence, or behind-the-lines ships with good communications gear for a combination of the two.
But I'd certainly want to steer away from having any
Galaxies at Wolf 359 when there are so many other ship classes to choose from. If we want to see a
Galaxy-like bridge in the deliberately nondescript shots of Hanson, we can say it's a
Nebula bridge.
Arguably, though, the
Excelsior that Hanson rode from Jouret to Wolf 359
should be among the ships lost in that battle - there's no reason why she should have left the system before the big fight. Unless Hanson hopped off her some time after the Jouret meeting, and this
Excelsior never went anywhere near Wolf 359 but instead was off ferrying some other admiral to some other location when the balloon went up.
It can also be argued that forty doesn't necessarily mean forty, but could stand for forty-two just as well. (Heck, in biblical language, forty simply means "a lot", generally "hundreds" - the Bible was put together well before this decimal business caught on.)
Personally, I think the idea of one surviving ship is more interesting. Which ship was it? How did it survive? Was its survival the result of a controversial decision by the captain to withdraw? Was it blind luck? We don't know the answers to these questions, of course, but they can be fun to explore in our imaginations.
Agreed. Although it's darned difficult to think why a) Starfleet would choose to withdraw any of its units or b) Locutus would allow a unit to escape. Surely out of a fleet of forty, a dozen ships should survive if Starfleet made a decision to withdraw! I mean, why would such a decision be made so late in the game that only one or two ships survive? At that point, it's clear this is Armageddon anyway, and there's nothing to be gained from staying alive because everybody back home, and eventually everywhere else as well, will be horribly lost. The Cube was destroying starships one by one, at a relatively sedate pace; there should have been plenty of time to choose the tactically sensible moment to withdraw, and OTOH if a dozen ships chose to withdraw, it should not have been possible for the Borg to shoot down eleven of those at the last second.
