Got it, and done.
preturn: It's about time Hangchow and Tatung grew up a little, so I switch them to Aqueducts. I switch a few cities from musket to cav production.
1380: Position more troops next to Madrid. Set worker fleet to chopping down some trees to cheapen these temples in the hinterlands. Upgrade a couple troops.
1385: Beijing builds marketplace -> cav (4 turns). It looks like we can get it down to 3 turn cavs once it hits size 12.
We begin the attack on Madrid:
Horse army kills vet musket, -5 hp (I mistook it for the cav army

).
Cav army kills vet musket, -4hp.
Cav army kills vet musket, -0hp.
Cav army attacks vet musket (-2hp) and retreats (eep!).
Cav kills vet pikeman, -2hp.
Cav attacks reg pikeman (-1hp), and retreats.
Sword army kills reg pike, -4hp.
Sword army attacks reg spear (-1hp), and retreats.
Cav attacks reg spear (-2hp) and dies.
Elite rider kills 2hp musket, -2hp.
Elite rider kills 2hp pike, -0hp, and produces General Tso! I can't resist and rename the unit Chicken

.
Horse army kills 2hp spear, -6hp.
There is a 1hp spear left, so I take a gamble and attack with our now 3hp horse army, which is our last available attacker and...
Madrid is ours! We capture Pyramids, Mausoleum, Colossus, Sun Tzu's, and Copernicus.
We sue for peace with Spain, taking them for everything they have, which is WM, TM, 30gpt, 46gp, Economics, and Music Theory.
We upgrade 3 horseman in towns that suddenly have barracks. Samarra switches to building a settler.
1390: Troops take some R&R in Madrid. Rush a worker in the starving Madrdid. Palace gets a little taller.
IT: Ottomans found Zonguldak in our territory, despite our escorting troops. Oh well, the defending spearman shouldn't pose much of a threat once we declare war in a few turns anyway.
1395: Begin moving troops to the Ottoman front, leaving behind a garrison of 3 cav in Eulbar to act as defense for the fledling western half of our empire. Buy an aqueduct and a temple.
1400: More troop movement.
IT: Babylon signs onto the Viking's war against the Ottomans. Ottomans manage to acquire saltpeter somehow, as the visible spearman in Xinjian turns into a musketman.
1405: More troop movement, war next turn.
1410: We declare war on Ottomans. We conquer Xinjian, Canton, Tsingtao, and Ankara while razing Izmit and destroying the new Zonguldak settlement near Madrid. We have no nationals left in Xinjiang any more, but I feel we have to try keeping it just on basic principles

.
1415: Reposition troops and heal. Some temples rushed.
IT: Indian settler lands at the ruins SE of Barcelona, escorted by an elephant. We still have 3 turns of peace treaty with India before we can attack without ruining our rep, although I don't know how much that matters with everyone furious at us anyway.
1420: Sinop razed. Antalya has Leonardo's, so I risk keeping it. I haven't seen any new muskets or pikes (just a bunch of spears), so I think Osman either lost his offshore suppliers of ore and saltpeter or is just plain broke

. Courthouse rushed in Madrid, which should allow it be half uncorrupt as long as they have WLTK day; it has significant tourist revenue.
1425: Salonika and Uskudar razed; we suffer our first casualty for the war (a cav).
summary: Old Spain is almost completely within our borders now, excepting the Indian settlement made this turn near Barcelona (which has an elephant defending it). There is also a Babylonian settler escorted by a pikeman wandering around near Toledo: we should be able to give it the boot in a few turns after the temples expand. Ottoman borders no longer touch ours at any point, and our troops stand poised to attack Istanbul. We have resisters in Ankara, Xinjiang, Antalya, and Tsingtao. There are 2 settlers, one having just arrived where I think it should settle in old Spain, and another near the Ottoman border, which I suggest we use to secure some wine. Our populace is about to become a bit disgruntled in 2 turns when our fur and gem trades expire, assuming we aren't able to renew them.
