I still propose
Focus one: Push through former Fort Combe territory to attack Monarchists. Do a mobile advance by focusing on using cavalry, light victoria I\II armed infantry, and Coombe mini-Cannons.
Focus two: Do a decisive push against monarchists going from Bradford to Newton Area. Concentrate most of our artillery on this front. Move all our navy away from the western shore to support offensive on the eastern shore (Shore bombardment, supply, minor amphibious landings). Issue many Watheley mk II pistols and some combe mini-cannons to naval crews and order to go for a bold boarding if they will encounter monarchist\loyalist\pirates shipI think we need to strike monarchists now because:
1) Soon they will have as many Victorias as we do
2) Our navy will not survive for long, trying to use that 1/7 of control of seas before it goes south is a nice thing to do
3) Unless monarchists developed some carabine weapon, we have HUGE advantage in cavalry. Same can't be said about Fort Alton
4) It is not impossible that Fort Alton will strike monarchists assisting our assault.
5) If loyalists will do landings against monarchists, than they will have even more problems to their morale.
6) We need some breathing room next turn in case if we will have to throw loyalists back into the sea. This means no monarchist forces near Bradford.
Let's go all out on the NPCs. The sooner they're out of the game, the simpler the situation become. Plus, we can get free designs.
A) Simplification is not our goal. Complex situations give more strategical opportunities
B) We can weaken Forty Alton and Monarchists will finish them off getting designs for themselves
C) If we deny Monarchists border with For Alton, then we can finish them off, without any fear that others will capture them and steal our prize
D) Independents gain one tech per round. Capturing them 5 rounds later is much better than doing it now
