Here are some military options for consideration:
The first thing is that if we are going to use our present Great Leader to rush a wonder (and it seems the popular consensus is that it should be JSB's Cathedral, and located in a city in the central south ie. perhaps Justinian or Macao), then the Wonder rush should be done immediately at the start of turn 0. This is because we are able to attack at least one of the two Aztec close contact units near Justinian with elite units and there is a chance of generating another GL. So - first up we should rush the wonder (if we are to do it at all), then smack that swordsman near Justinian and hope for the best.
More generally, it also seems that the popular consensus is for a quick peace with the Aztecs. I strongly support this goal, because there is little value in stretching this war out and we should try to avoid escalation and the involvement of other powers. However, I really do think we should try to eliminate the 2 close contact units (as outlined above). If Peace is achieved within the first 2 or 3 turns, then my recommendation 5 is redundant, and recommendation 5B is substituted. Recommendation 1-4 are submitted regardless of the Aztec hostilities.
1. Galleys near Lutetia - let them either attack us or retire. We should not attack because (despite co-rated att/def values) it see,s gallies always do better in defence in 1 on 1 battles. Why? - I don't know. I also note that ships can fortify at sea (not sure if our galley in fortified or not) - we might as well do this, although I'm unsure whether it makes any difference to defence values.
2. Boost Lutetia garrison - we can transfer 1 Musket from Eyr and also 1 Musket from Fox Nest. When the first Musket arrives then transfer the Pike in Lutetia back to Fox Nest for upgrading to Musket. The result is 2 Muskets in Lutetia and Fox Nest each and 1 Musket in Eyr - a much better defensive deployment. We could, do 3 in Lutetia and 1 in each of the other 2 cities (by putting the upgraded Pike/Musket from Fox Nest back in Lutetia) but I prefer to leave a reserve in Fox Nest for contingencies and capital defence.
3. Move the Catapults - at the moment there are 2 catapults in El Armana and Civanatoria and these locations are not really exploiting the value of these units effectively. I think we should transfer both to Abydos, Memphis or Thebes where they are closer to the borders and/or can provide Forbidden City protection. Obviously 2 catapults cannot go into 3 cities, so we just need to choose which 2 (of the 3 candidates) is the best location.
4. Army near Tlaxcala - should be relocated to Heliopolis, which is well positioned to stike or defend from. We can then transfer 1 Immortal from Heliopolis to Alexandria.
5. Justinian forces - First deal with 2 Aztec close contact units. Then begin to assemble an expeditionary force to assault Xochicalco. Here's how it goes. We can put a force of 10-12 units (at least 4 of them elite) in the field within 2 - 3 turns. This will require the Knight near Asyut, the 2 Immortals in the field SW of Cumae and all the forces actually inside Justinian except the Musket and the regular Pike. It will take 2-3 turns to eliminate the close contacts, heal presently injured units and muster. The muster point should be 2 tiles SSW of Justinian (presently occupied by the Aztec swordsman). The proceed thru Greece, avoiding Babylon and giving Corinth a wide berth, SW to Xochicalco.
NB. If Plan 5 proceeds there will be a strong need to bolster the Justinian garrison - we could just rush a Musket (cost would be about 190 gold!) and/or relocate a defender from Macao. The situation can be further plugged with some new Knights which are due for completion over the subsequent turns (Fox Nest starts this in 1 turn, followed by some more). Defensive deployment will also have to take account of the location of JSB's Cathedral (if rushed).
5B - Peace with Aztecs in 2/3 turns - Justinian forces simply need to be partially dispersed and garrisoned. We should keep strong units there, and in Macao, but if JSB's Cathedral is located in one of these cities then this city should be our HQ.
