(0) 560AD What a messy situation we're in. We've made gains against France but under the Honorable ruleset (no razing or abandoning of cities) we won't be able to keep them due to culture flipping. The only real solution is to press on until we (hopefully) kick France off the continent, or until our republic collapses. Fortunately we've cut off France's only saltpeter supply, and the F4 screen shows that they are not trading for any (only active trade is with Persia, who has no excess saltpeter). My first decision is for our leader; I consider using him to rush the Forbidden Palace, but none of the newly conquered cities are secure enough for that. I could rush it in a city next to our palace... but at only 200 shields, we could build the thing there in short order. No good wonders are available either, so... the best option is to form an army of riders and open up the possibility of the Heroic Epic and Military Academy. I want to strike in the southeast first and move north from there to establish one unified front against France instead of 2; Riders shuffled slightly to that effect. Hoping for no flips, I end the first turn.
(1) 570AD A French knight kills a Rider, though it goes down to 1hp in the process. Chartres flips back to France as well; they get a pike as defender, so they definitely do not have saltpeter. WTH?! France somehow has TWO pikes in Chartres?! How is that possible? That is.. not fair. It didn't flip until our turn... Looks like the AI is using "scroll-ahead" exploits here. We recapture Chartres anyway however; at least it is down to size 4 now... Our army kills the 1hp French knight and we can now build the Heroic Epic (that will be a post-war project). In the south I pillage France's former saltpeter source so that in case Rouen flips back they won't be able to upgrade pikes.
(2) 580AD A French knight again kills a Rider and is reduced to 1hp in the process. They also land three knights by ship on the mountain next to Chartres - I had to move the units on it off in order to retake the flipped city *sigh* At least no flips this turn. I save a turn on a Rider by rushing 10 shields on a sword in Canton; I will proceed to do this over and over again on my turn in cities which are getting 20ish shields/turn. Building up attack force in southeast. I also notice that Bensancon is NOT in resistance, so I begin rushing workers there to eliminate the French nationals.
(3) 590AD Bad, bad luck in the north. French knight takes NINE hp off of our Rider army before doing the graceful thing and dying. Another knight attacks and kills a fortied vet musket (in a city, no less... where's the random number love?) Two more knights move onto the mountain next to Chartres as well. I hate that mountain!!!

One good thing about this warfare is that the tech race is almost stopped cold; France was the one pushing it forward. Situation is great in the south, dire in the north. Let's see what happens next.
(4) 600AD Terrible news - France retakes Chartres. And not even a bad RNG turn, they just pulled EIGHT knights out of nowhere to attack it. They have a frightening amount of units up there. Our Rider army killed two knights before dying... War weariness is off the charts, so we have to make peace this turn or go to Monarchy - yeah right, like we would be able to survive 7 or 8 turns of anarchy while at war. Not likely. So it's time to press for as much as we can get on THIS turn and then sign peace. Amiens is captured in the south (loosely defended with two regular muskets). Chartres is retaken in the north from France as well. Avignon comes to within a 2hp musket from falling to our forces, but it turns out that 10 Riders apparently can't kill 2 muskets and a pike.

Having stretched as far as we can go, we now have to make peace from the war weariness. Hmmm - we can get either a lot of money from France or a useless colony. I opt for the money, since it is unlikely we can prevent a French colony from flipping away from us. Our approval rating goes from 45% to 83% immediately.

Now the tough part: trying to keep the captured cities from flipping away from us. That will occupy the remainder of my turn. Most of our core cities switch to banks to get the benefit of the last few turns of our Golden Age.
(5) 610AD Gandhi comes calling asking for a military alliance against Babylon. We decline... Physics has been discovered by civs other than France, and remarkably India has it. (?) They have the best price, so we buy it for 1389g. I expect to be able to broker, but it turns out that both England and Germany cannot offer even 1gpt for it (figures...) I sell to England for 250g, Germany can't cough up nearly enough to get it. A diplomatic mistake on my part - sorry guys. France has Magnetism but not Metallurgy or Theory of Gravity. Looks like they are 1 tech ahead at this point.
(6) 620AD Resistance ends in every French city and we get a palace expansion!

Please, please, PLEASE hold out a few more turns until I can rush all the foreign nationals out with workers and settlers!
(7) 630AD Our civ's Golden Age comes to a close. Bensancon is our first 100% safe city from flips - no tiles in its 21-space radius controlled by France and only one foreign national in the city, which has two units suppressing it. 0% chance to flip. If the cities around it flip though... Cherbourg is the only one really worrying me at the moment. 6 foreign nationals and it juts right up against the massive culture of Rheims; I've got a bunch of units in there but still not enough for 100% suppression. Please hold out on me until I can rush settler from there.
(8) 640AD We survive another turn without losing a city.
(9) 650AD France starts Newton's so they must have Theory of Gravity. France is two techs ahead (3 if you count Democracy, which I don't) and everyone else is on par with us or behind.
(10) 660AD Our first bank completes in Beijing, we start the Heroic Epic there. Rouen is now safe as well, at size 1 with no pressure from French culture, and with two units in it. Leave two units in Rouen and Bencanson at all times!
Notes: Our war was somewhat successful; if we had just gotten Rheims in the opening turns we would be in excellent shape. As it is, that city juts into our territory badly and needs to be taken into account with the culture flips. Chartres has 7 tiles of its 21-tile radius controlled by the French and 1 French national; it won't be safe until there are 16 units in it. I suggest rushing cheap swords or producing them out of Beijing until we have that many. Chartres' cultural radius should expand in 2 turns and reclaim 3 tiles from France; if that is the case, we will only need 10 units to keep it safe. Next turn the cultural radius of Cherbourg and Amiens will expand and they will both be at size 1. So we will need 8 units in Amiens to safeguard a flip and 8 in Cherbourg as well (I did click next turn to see the border expand, so we at least won't lose any next turn). Priority number one is keeping the cities that we fought so hard to gain, then after that to building up our infrastructure for the industrial age. In summary, here are the number of units we need for each city to keep them safe:
Chartres: 10 units (after border expansion)
Cherbourg: 8 units
Amiens: 8 units
Rouen: 2 units
Bensancon: 2 units
So long as we maintain these forces there at all costs, the cities cannot flip away from us and they will remain a valuable part of our civ. Unless of course I have misintepreted the flipping formula in some way; you need (foreign nationals + tiles controlled by other civ) * 2 to completely supress a flip, right? Someone correct me if I'm wrong.
And if France gives us the opportunity, we will finish the job against them with tanks...

Side note: we want to build the Forbidden Palace immediately. I suggest Xinjian, which will let us move the palace at a later date. Also, the Heroic Epic in Beijing will probably turn into a Wall Street prebuild, since we don't need the Epic at the moment.
