It's okay, don't worry
You could have also unloaded the stack to Tex 1W of the city. Since the southern city only had 20% culture, we'd be free to move.
Don't worry about the GG, he's safe.
Our worries for now should be simply to finish off every city in a timely fashion. We can do it in 8 turns at most, 6 is the limit I think.
I'm going to reverse an earlier statement:
no more Trebuchets in the south! Units and galleons that can reach Oz or Mansa's last cities within 6 turns.
Aztec:
Texcoco
Don't leave the sword alone, it can be picked off by the WE. The city should fall within 3 turns, you can suicide the Trebuchets if need be.
Malinalco
Same as above, no problem here.
Tlaxcala
Send back Galleon 21&5 to pick the troops next turn (T173, some units can walk 2 tiles to galleon 5) on the silver mine. Unload T174 NE of the city bombard T176 and probably T177. Take city T178.
Tlacopan
Should fall T173. Bombard with 4xp Treb (we need him for later) and attack with 2xp Treb.
Calixtlahuaca
Troops from Tlacopan move T174-175, bombard T176,177, take city T178.
Tula
Unload the troops in TzinTzunTzen next turn from Galleon 27.
Walk down there and take the city.
However those units are quite weak, so take the worker 1NW of Tzintzuntzen and send him to make a road UNDER the stack you landed off the road for
Wadan with the help of the worker there. Road should be finished T174 and allow troops from Wadan to go help.
HOWEVER, since this city is basically useless to the AI, leave it alive until the last moment possible. This city we will kill only after Oz is dead.
Monty dead ETA: T178~OZ death.
Mansa:
Timbuktu
Bombard T173, T174 bombard, then take. We don't have many units there, add 1~2 for safety.
Agades
Those troops are heavily wounded and not sufficient. Pick up the 2 maces sitting just north of there. We can delay the taking of this city for a few turns, better than losing units there.
Awdaghost
We need to be there in the next 4 turns with at least 2 Trebuchets and 1 unit. Do whatever it takes. Get a galleon of units the following turn there.
Wadan
Overkill
Do upgrade the WE into Combat line before ending the turn.
Don't forget to get a road UNDER the stack with the 2 workers close by. You could have landed 1E and saved yourself a headache
Mansa dead ETA: T177~178
Gandhi
Kohlapur
We should be okay here.
Vijayanagara
Try to save the Trebuchets as much as possible because we are low on them and high on units. Try using the Accuracy guys and if that gives you good enough odds go for it. (Save the CRIII for Delhi)
Delhi
Some of the units heading there already have to split and head to the bottom city. Send only 1 Trebuchet and minimal troops to protect it. (WE, XBow, 2~3 Mace).
Amhedabad
Use most of the troops from Madras to go there. We will have to reinforce with Trebuchets that are next to
Texcoco or risk losing big. Load the galleon with 1 promotion with 1 extra Treb and send it on its way THIS turn, land 1E of city.
Gandhi dead ETA: T177~178
Oz
Based on the above, we have about 6 turns to mass up as many galleons with units in them and get them to Oz.
We have a bunch of troops on their way, but they are a bit far.
I will examine the save more and try to see what troops we can use for this task.
