As it turned out, I was initially too busy Pillaging Cottages to notice Huayna's obvious Iron Mine (a mine on a flatland Plains square that didn't have a Resource bubble), so Huayna had the opportunity to use his Iron for a couple of turns.
However, he failed to build a Spearman. If I recall correctly, he built a Swordsman, but my forces from the south, north, and those dudes to the east that are wasting time Pillaging Cottages instead of Pillaging the Iron Mine all joined up and attacked Huayna's capital. It was defended with 2 Archers + 1 other Iron-based defender (I'm pretty sure that it was a Swordsman). Holy City Shmoly City--it got razed along with the others.
India HAD connected-up their Horse Resource and Iron, but had no Spearmen... during my first war with them, I saw an Axeman, a Swordsman, and a Chariot, as well as a few Archers. Asoka's first two Cities fell, after which I Pillaged his Horse Resource (which was still within his capital's Cultural Borders, even though I'd razed the City that could work said Horse). I also Pillaged all of his Mines that were connected... you can see that I ignored the Mine to the south of his Horse Resource, since, if it did contain Iron, it wouldn't have been connected to Asoka's Trade Network and thus would at best have been a second source of Iron, but would still not have been of use for building units.
I sued for peace while my Chariots healed-up and while reinforcements arrived. As you can see from the screenshot below, I actually had quite a large stack of Chariots at that point, thanks to ignoring all of the other AIs for a while... I really wanted to kill off all of the farther-away AIs, so that future attacks could be focused on spamming units, accomplishing goals at the cost of many units (and thus saving on Maintenance Costs due to units dying quickly), followed by getting the next set of units into the action that much quicker.
Asoka managed to rebuild another City to the south before I captured Delhi. He also managed to bring in a Chariot from out of nowhere to take out one of my southern-approaching Chariots, but the City fell the next turn, eliminating his Chariot by default, hehe.
Oh yeah, I razed his Cities. Great Wall? Scotland Yard? Buddhist Holy City without a Shrine? Who needs those?
While I was busy with Gandhi, Copper had popped at some point... I only noticed when I looked in one of my Cities and was happy to see that I could finally build Impis. I thought that I'd perhaps managed to connect-up Augustus' source of Copper (I'd captured his Copper City earlier. Perhaps I took that City during the 10-turn Peace Treaty with Asoka that I used for grabbing Mysticism and another cheap tech while also regrouping my forces). As it turned out, Augustus' Cultural Borders still controlled his Copper square... which was still un-roaded and un-mined... so I only got Copper access due to the Mine popping it. Chariots were still working out fine anyway, but it was neat to actually be able to build Shaka's Unique Unit.
Okay, here is where that screenshot went--the one of Asoka being eliminated.
As my western Chariot army returned eastward, it took out one of Gilgamesh's Cities and well as a ton of his Workers that weren't expecting me to use the Roads that were previously within his Cultural Borders in order to capture a ton of said Workers!
It looks like he was trying to get his Horse Resource connected, but didn't manage to do so.
There's yet another source of Copper. I think that getting a source of Gems or Silver would have been far preferable, but I'll take the extra 2 Hammers with a smile, thank you very much!
Sometime thereafter, I finished off Gilgamesh, then focused my attention on Boudica.
I foolishly allowed Augustus to build The Oracle, which he used to grab Feudalism. Oh well, I'll take him down eventually.
I forked three of Boudica's Cities, two at a time, alternatingly, until she would leave one of them lightly-enough defended for me to take it down. Here, you see me razing the second of those three Cities, with the third one being her capital.
Getting a Gallic Warrior made her confident, so she first sent out an Axeman + Spearman combo that I ignored, followed by sending out her Gallic Warrior. It was time to strike! Thanks to an amphibiously-landed 7-experience-point freshly-build Catapult (Barracks plus 2 settled Great Generals), I was able to take her capital without losses... two Catapults retreated and the rest of her 3 defenders were easily eaten-up.
After that point, I went to bed, hoping to continue the game in the morning, only to find that the power had gone out overnight. So, I only have the autosave before the attack. Oh well, if I play on, at best, I'll play no better (losing 0 units) or at worst, I'll play a bit worse and might lose a unit or two assaulting the City--if that second siutation happens, I'll just accept it instead of trying to reload until I get my previous good results in that battle--a couple of more unit losses for capturing a capital will be a worthy sacrifice.
I kept this City (and will keep it again if I continue playing the game) due to it having The Great Lighthouse. It also happened to have a nice settled Great Prophet.
Augustus will take some work, but Boudica is willing to give a TON of expensive techs for Peace... so, I'll probably raze or capture one of her two remaining Cities, take Peace for techs, then focus on Augustus. 1-on-1, I should be able to tactically beat him, even if he does have good City defenders. Of course, I have Ivory, so if I get a great Peace deal from Boudica, Augustus will be begging for mercy soon enough.
I've also kept a reasonably-large Pillaging party near Augustus' Iron, since he did manage to get his Iron connected briefly and I don't want to see that situation happen again. He hasn't bothered to try and connect his Copper since it is techincally within my big fat cross (even though it's still within his Cultural Borders), since he (rightfully) feels that it would not be safe to send his Workers there.
Augustus did raze a newly-founded City of mine that I'd built for Cow + Dyes next to his Cultural Borders, but I didn't really need the City and I can always rebuild it if I really want it badly enough.
5 turns of City Revolt should be plenty of time for me to be able to Pillage all of Boudica's Cottages. So far, I have not built or worked a single Cottage the entire game, keeping to the original theme of this thread.
