in I, Borg there are Borg ships freely moving about near (or in? I can never tell with TNG) Federation territory.
Sounds like it's actually a case of the Federation advancing: Picard says he's scouting out this Argolis Cluster for possible future UFP colonization.
Later in "True Q", Picard offers aid to one of the native cultures in the Cluster, suggesting he didn't exactly "fall back" after spotting the Borg. In the Dominion War, this territory is suggested to be a gateway from Dominion/Cardassian holdings towards the core of the Federation, and it doesn't appear as if a Borg presence would be a factor there.
Has Endeavour's, and Amasov's, story been told in TrekLit anywhere?
There's a comic titled
Loyalty that says Joseph Amasov commanded the
Endeavor at Wolf 359 ("BoBW") and a RPG booklet saying he did it again at Earth (ST:FC), surviving both fights, and another from the "alien spotlight" series simply titled
Borg that mentions him acting as a Borg expert.
Nothing in the novels, though - no first name is established for Amasov in those. An
Endeavo(u)r is name-dropped in the Friedman novel
Saratoga, without specific mention whether this would be the same ship Amasov (once) commanded.
If Hansen is commanding the battle fleet from Melbourne rather than a tactically more-powerful Nebula or Ambassador, that suggests to me that Melbourne is a dedicated command ship and that Hansen was in the command station
This is quite possible. OTOH, naval commanders ITRW have chosen "weak" ships as their flagships for a variety of reasons. Before effective realtime radio communications, fast ships such as cruisers were more useful for commanding than the cumbersome battleships; once radio emerged as a factor, battleships were disadvantaged by their very firepower, which tended to massively disrupt radio communications (the broadsides ripping out the ship's own antennas etc.), so those naval powers that could afford it fielded dedicated, essentially unarmed command ships; and now there's all this effortless networking, allowing the battle to be conducted from aboard just about any ship, with the hiding of the actual command ship's identity perhaps a factor in the choice of that vessel.
Are
Excelsiors, the preferred command ships in TNG (see also "Descent"), nimbler than the big battlewagons? Nothing onscreen suggests this. Are they so inferior as to be relegated to behind-the-lines command duties? The fight at Wolf 359 had the
Melbourne dashing in rather than standing off. Are they inconspicuous? Depends on how communications traffic can be monitored by the various enemies and hidden by Starfleet. (On the latter, one would assume
all ships would be transmitting and receiving like there was no tomorrow, so the enemy would specifically have to divine the content of the messages rather than just their existence.)
A DS9 "Field of Fire" reference suggests a crew of 1,200 or more for an
Excelsior. Command staff aboard? Troops being transported? An aged vessel requiring massively more crew than her more modern counterparts? OTOH, the episode doesn't really specify the class of that starship - it's noncanon inference from background material only. Might be a
Galaxy or a
Nebula instead.
