Turn 501 brings me the size historical popup. I'm in first, as expected given the size of my points lead over everyone else. Unusually, Frederick is in 2nd, but he's Russia with only 7 cities. His cities must be really large. Menelik II is 6th, even though he has more cities than I do (he's the Hittite leader in this game). His cities must be very small. Gilgamesh is still in 4th, even though I've burned two of his cities and three others rebelled.
Combat Sports is my next technology. This gives me Arenas.
The First Army burns Guimaraes. Their target now is Lisbon. I also notice a fairly substantial stack of Portuguese units headed towards me. They were probably meant as reinforcements, but burning the city stopped them.
Kublai Khan offers a tech trade that I'm willing to take. I don't like to trade current techs, and I especially don't like to trade current military techs, but I am willing to trade Ancient Medicine for Philosophy.
On the research front, I get Drama. I need this to build up to Music.
Meanwhile, Gilgamesh's power level may only be 0.4 of mine, but that doesn't mean he can't counterattack. This WAS the Second Army on turn 500, besieging Coimbra:
Plus a few more Swordsmen arriving as reinforcements:
Unfortunately for me, this was the counterattack force Gilgamesh had built up in Coimbra:
The resulting counterattack costs me nearly my entire Second Army. The only units to survive were one Swordsman, the Healer, and the General. The Second Army has to retreat to Atico to rebuild. The only really irreplaceable unit in that stack was the General. As long as he survives, I can rebuild.
On the diplomatic front, I am finally able to make some deals due to having rivals that I'm not out for the immediate blood of. I sign an Embassy agreement with Lincoln:
Embassies give a small diplomatic bonus and allow trading of certain military units (siege units, ships, and Workers primarily). They also allow you to see into the other civilization's capital. I haven't actually located any other capitals, so this will have to wait for now.
Then, I sign a Right of Passage with Ashurbanipal. This acts like Open Borders, but for defensive units only. This is a prerequisite to Open Borders, which are rarer in C2C.
The stack of Dog Soldiers that I built so long ago is still hanging around. I move it west to keep an eye on Washington. It's sitting just northwest of Ica. Even though I'm fairly sure he won't attack me, you never know what might happen.
I research Music, because it's a prerequisite for Theology.
One thing about leaving the ruins of burned cities behind is that they can generate Treasure units. Treasures are non-combatant units that can either rush a building or wonder like a small Great Engineer or conduct a trade mission like a small Great Merchant. They can also build a Treasury wonder or a Museum building (this shows up in the Industrial era at Scientific Method) on their own. I park this one for now and hold onto it for later.
Lincoln sells me contact with Hammurabi of Spain. Spain must have come out of minor civilization status. Buying and selling contact with other civilizations is something you can do in C2C and I have neglected to do. I'll have to remember it in conjunction with the Ishtar Gate.
Theology is my next technology, and I immediately put Cuzco to work on the Hagia Sophia. It will take only 3 turns, without burning any slaves.
Meanwhile, on the war front, the First Army has looped around to the northeast of Lisbon and the newly-formed Third Army is attacking from the west. The two armies have Lisbon in a vise, and the resulting battle generates my fourth Great General, Merneptah.
The two armies finish off Lisbon's defenders between them, and I capture the city. Unlike all of the other cities, I choose not to burn it, and instead sweep in a garrison force of Longbowmen and Light Crossbowmen to hold the city.
Lisbon was supposed to have two Wonders -- the Bison Trainer and the Deer Trainer -- but it turns out not to have any when I finally take the city.
I think what had happened was that the chance to capture one of these wonders was mis-set to 0 (never capture) instead of 100 (always capture). There are several wonders in C2C that have this problem. Nevertheless, Lisbon is still the holy city for Druidic Traditions and Shamanism and will serve as a source for Culture (European), so I keep it.
Along with the Longbowmen and Light Crossbowmen garrison force, I have one last unit to send to Lisbon: a Story Teller. Costing only as much as a Spearman, Story Tellers have the ability to create a small Great Work. While it provides much less Culture than a Great Artist (12000 Culture for the Artist, only 21 Culture for the Story Teller), its Great Work is just as good at ending a revolt.
The Story Teller quickly ends the revolt in Lisbon. The capture of Lisbon has put all of the eastern half of the continent under my control. I am now free to march my armies west and finish off Gilgamesh.
