Thank you for the topic, locarno24. Sounds like an interesting what-if. Other thoughts in other replies, but I just wanted to address the above: the Manticore Binary System was probably the toughest single-system defence anywhere. Remember that the biggest SDF in the League was Beowulf and in 1922, they had about three dozen SDs. Manticore had 10x that.
Outside the League, the only navies of notice in 1900 were the IAN and the PRN. The IAN was smaller than the RMN (was probably surpassed in the last couple of decades of the 19th century), but unlike the SKM, the Andermani Empire actually had multiple systems to defend. The RMN in 1900/1901 had basically a single (albeit binary) system where to park its entire fleet.
Even after Second Fleet moved to Yeltsin's Star, the MBS was probably still the most heavily defended system.
Of course, holding the system is a different story. If you punched out the BSDF at Beowulf or the Capital Fleet at Haven, you'd still have to fight all the rest of the navies in question who'd be coming for you. If you punched the RMN out of the MBS, you've won.
This reminds me of Operation Medusa in the Castle Federation series. Without going into spoilers (it's a good series, 6 books only, worth a read), sometimes achieving temporary superiority is sufficient.
