Good estimates, but I won't give hard numbers in here.
LC Toshiro is, of course, going to have to send for help, but, he won't have to run before Cathy gets there. Maybe immediately after, but, not before.<P>Incidentally, you're very close on Toshiro's battlegroup.
The Shogunate uses basically a single root design for their Major fleet vessels, with a modular setup to construct variants, The usual layout being that, in a battle group, there will be two "Pocket Dreadnoughts" (essentially heavy destroyers), two "Pocket Carriers", (He's lost one of those.) two "frigates", (Multipurpose vessels, both heavy weapons, and fighter complement), and a "Flagship" (basically a light carrier with additional C3 capabilities). Lighter vessels usually include 4-6 Corvettes per "Warship", with a variable number of fighters. Overall capability, when utilized properly, can take down a Dreadnought.
Toshiro's Sub-Captains weren't experienced enough to do this, thus, he lost 3 vessels piecemeal,(two Destroyers, one Light carrier.) mainly due to mistakes made early on. "Shogunate" fits only as the reference used commonly among Spacers and Outsiders. The Official term being "Loyal Servant Nation to the Emperial Legacy", which is a mouthful...<P>------------------
