Extended 3 hours a bit, sorry
Inherited turn (980 AD): It appears that certain cities produce wealth. I change these. Try to get the Maya p***ed off, but can only get them to furious - they won't declare war (understandably!). The Dutch aren't quite dead yet, but they've only got 1 city.
IBT: Barca bank -> Smiths. I removed some entertainers, so We love the Sapa-Inca day is off.
Turn 1 (990 AD): Workers, workers everywhere! And not a job to take!
IBT: Persepolis riots. *spanks self*
Tiwanaku bank -> uni.
Arequipa bank -> mp.
Turn 2 (1000 AD): Movement of units into Mayan territory (naval only)
IBT: The Mayans say that our invasion constitutes a declaration of war. We say "Yup, wanna argue with these swords here?" and declare war.
Cuzco bank -> uni.
Seville bank -> med inf (was about to build aqueduct until i realised the cost).
Toledo bank -> med inf
Vilcabamba bank -> med inf.
Turn 3 (1010 AD): Unload 5 crusaders, 3 med inf, 1 elite swordsman, 3 trebuchets near Copán.
IBT: Diversionary force wiped out. One crusader lost.
Turn 4 (1020 AD): 2 Trebuchets takes 2 HP off a Javelin Thrower defending a Longbowman.

In Lagartero: Med Inf kills spearman 3-3.
Med inf is killed by spearman 0-4
Med inf kills spearmen 3-2.
Med inf is killed by spearmen 1-4. Opposition promoted.
Med inf kills vet spearmen 3-1.
Maya are at Anarchy. That's something.
Make a huge mistake when moving units and leave 3 Trebuchets with only 1 crusader.

ops:
IBT: Amazingly Trebuchets are left alone - they go for Copán invasion force.
Chemistry -> Metallurgy.
Persepolis barracks -> temple.

Vet med inf is killed by fort vet Spearmen 3-4 (this isn't my day!)
Elite crusader is killed by fort vet Spearmen (1 hp) 0-2 (THIS REALLY IS ANNOYING!)
Battle of Lagartero:
Vet med inf (3) kills spearman 4-1.
Vet med inf (2) is killed by longbowman 2-2.
Risk a vet med inf and win 1-0 against the longbowman.
Fortify the workers cos I can't be bothered.
Please note that the stacks of workers are fortified
IBT: 1 crusader is lost.
Arbela harbor -> med inf
Toledo, Vilcabamba med inf -> med inf.

Resistance in Lagartero has ended.
Turn 10 (1080 AD): Move units. Kill a longbowman.
Do note that some units are on go to. These are either sent to pick up others or to unload or to be picked up.
End notes: I guess the war is going OK - we could benefit from more units from the former Spanish land, which will come soon. Please keep producing units - maybe starve the Mayan cities down to 6 so we get the support bonus.
Do not build aqueducts.
Somebody else could perhaps take the time to author another attack plan - war isn't my strong point.
Mayas are in democracy, so ought to be suing for peace pretty quickly with their huge cities...
Fight on
This is played in C3C v1.15 btw.
