A few parts of this agreement still need to be specified, but here is what I have so far. As long as
@Northerner agrees to section 1, I can play my turn (by transferring the cities instead of conquering them). France is willing to entertain counter proposals on the specific details of this agreement.
Armistice Agreement Between French And British Empires
1. Immediate Obligations
The British shall immediately return Brussels, Brest, and Lyon to French Administration. (The section 4 payment provisions do not apply to these cities.)
2. Hostage Cities
Britain shall remove all troops and other units from the following cities:
Plymouth, Southampton, Birmingham, Newcastle, and London.
France shall remove all troops from the following cities:
Ambovombe, Tananarive, Diego-Suarez, Sofala, Sao Sebastiao, Noumea.
Troops may be kept in ships near these cities to ensure that they remain empty, and may attack and capture any of these cities that stations a unit inside. Units may still be produced in these cities, but they must be moved out during the turn.
3. Surrender Procedure
In the territories which the British Empire agrees to surrender to the French Empire, the British will specify certain cities as "Evacuation Ports." All units in the surrendered territories shall travel to an Evacuation Port as quickly as possible, and all other cities shall remain empty. France may send patrols and station troops to make sure this is being observed.
The number of evacuation ports should be approximately 1 sixth of all surrendering cities (or fewer).
Once units are withdrawn to the Evacuation Ports, France and Britain shall agree to de-mobilize (i.e. return to the house rule for waiting a turn after a war declaration). The demobilization shall not apply to the hostage cities.
Britain will not be forced to surrender cities to French administration until she has had a chance to deliver all supported trade units and re-home all other supported units to a city which Britain shall retain after the completion of this agreement.
France will deliver sea transport capabilities to the Evacuation Ports to speed the departure of British Assets. These shall be returned to France, unless kept as payment as specified in the next section.
4. Payments for Surrendered Cities (to ensure buildings are not sold, cities are not starved)
France agrees to pay Britain 1.3 gold per shield of production cost for improvements remaining in surrendered cities. This payment shall occur immediately upon city transfer.
Britain may retain evacuation shipping capacity provided by France at the rate of 20 shields per citizen surrendered. Britain may accept a payment of 35 gold per citizen instead, or 45 gold if France did not provide sufficient transports to pay for that citizen. This payment shall occur after the final city is surrendered.
5. Cities to Be Surrendered
Exact list to be specified, but general idea
Definitely to be surrendered: India, British Middle East, British Egypt and Sudan
Definitely to remain British: British Isles, All Territory in America and Atlantic Ocean Islands, Australia, New Zealand, British South Africa, some islands near Australia.
6. Exceptions and Additional Obligations
More might go here based on a closer look and the course of negotiations.
Chengdu: Britain shall have the option to give this city to the French, or to the Japanese (for whatever payment or concessions Britain can get) or to grant the city its independence (i.e. give it to the Independent Civ).
For the duration of this agreement, the British Empire agrees not to research, or acquire from others, the technologies for Steel Alloys or Large Calibre Guns.
7. Trade
Britain and France shall return to the trade relationship that existed before the war. Britain shall not have the right to embargo French goods until the surrender of territory is complete. France shall not embargo British goods without first lodging a complaint that the British are in violation of some part of the agreement, or that the surrender of territory is taking too long. After such a complaint, the British will have at least one more turn of access to French markets, providing time for the disagreement to be resolved.
