I started whipping and chopping axemen in all my three cities (the third city first whipped a monument and a barracks of course).
22 turns later I declared war and moved in with a stack of 9 axemen. Perhaps I should have brought a spearman with me but that's debatable.
In any case it turned out that Louis only had an unpromoted archer in the city and he whipped an axeman before I could attack but I only lost one axeman.
Here I made my first huge blunder as I razed the city, not realizing that it was the jewish holy city! Earning me unnecessary demerits with Hannibal on top of attacking his friend and wasting a potential future income source. I was sure I had checked the city but there you go, maybe I need to stop playing for a while and grab something to eat.
The 6 non-damaged axemen then proceeded toward Paris and was split in two groups with one group keeping an eye on the city whilst waiting for reinforcements and the other group moving down and pillaging Louis only source of copper.
A few turns later I captured the capital.
At least I kept this holy city.

But with corn, cows, gold, horses and silk in the BFC, who could blame me? I had finished researching IW somewhere after razing the first city and now decided to do some deficit research to get writing for libraries, but first I needed pottery.
After razing the southern city (and forgetting to take a screenshot again) I healed up and then moved on Orleans.
The large number of axes with combat2 is due to Louis moving around and attacking with lots of chariots during the battle of Paris and the fact that I had multiple stacks for pillaging and strategic defense against chariots descending on my virtually unprotected homelands. I probably should have brought more spears but I anticipated a much fiercer resistance and more casualties during the city attacks.
After capturing Paris, Louis had no more axes and could only use chariots and archers which my advancing army didn't complain about. Orleans soon fell.
I deliberated for a few minutes wheter I should keep it or not since my economy was running solely on plunder at this time with even a 0% research deficit. In the end I decided that I couldn't afford to risk Hannibal stealing the ivory and that the city was of to much strategic importance as well as in a good spot, so I opted to keep it.
Hannibal has a big tech lead as well as about the same number of cities and a higher power rating than me and he's only at cautious (with an unnecessary -2 demerit from razing the jewish holy city

). I fear he might come after me with oliphants, and I want some of my own should that, Vishnu forbid, come to pass.
After finishing writing I immediately switched to libraries on the homefront which I whipped as soon as possible.
I also founded the decidedly unholy city of Texcoco at my preferred location. A few turns later I got a glimmer of hope regarding my backwardness as a great general was born abroad, hopefully indicating some strife and turmoil to keep my opponents back.
My gold was running low and my troops were getting restless, it was time to continue the glorious offense.
This time I razed the city though it might get refounded later on. I see a pattern here, raze, keep, raze, keep, raze and as it turns out, I'm probably going to keep the gold horses wine city to the east.
Hopefully Louis founded another city 1NW of the sea tile to so I can get another 3-food-resources-city without having to ask Hannibal to relenquish it. Perhaps a good future drafting city?
I plan on moving my capital to Paris and making Tenochtitlan my GP farm. The abundant food and whip-happy nature of my people means I'll probably go for a SE, at least early on.
