I need help about strategy on this one. I don't remember exactly how civ 4 works.

He does have 19 cats on hand. IIRC, it will be useless to stack units in the city. They will get killed by the units after he sacrifices all the cats.

I should instead build a stack of my own and strike when he is inside my roads. This will mean loosing the city, but I don't think an can do otherwise.

Or will the city defense protect me from collateral damage?

Well Civ4 mechanics will protect you somewhat from cat attacks. IIRC it's the top 6 units lose a percentage of their health with all collateral damage. He also has the axes to suicide if necessary. It really depends on what you have, with a stack that size unless you have a decent amount of cats/he plays poorly then you are screwed.

I would say a better option would be to sue for a peace treaty, potentially ceding that city in return for 50 turns of peace or something like that. Alternatively, convince someone on his border to invade. I don't know what the power graphs look like but he surely wouldn't have much more left hanging around anywhere.

How many units do you have? If more in his SOD by a margin (5-10+), you can sit it out in the city and kill out his SOD with crossbows in the retaliation attack. If not, it is a tough call. Need also about 25+ cats to be able to attack that stack of oromos with crossbows. Also, need to upgrade however many axemen you have IMO.

It looks like a well planed attack comming from 2 civs.

I've left only 2 defensive units in both cities and regrouped most units in a future SoD.

I don't think this will be enough, but we should go down with a fight.

Yep, that's coordinated ;)

To answer your question: in CIV the attacker ALWAYS has the advantage if he brings a mixed stack, unless you have more catapults than him. The reason is the very powerful collateral damage and the city attack boni for catapults. Thus, either you can weather the attack - but be prepared for ridiculous losses if he has enough units to mop up your wounded after using his catapults. Or you must pre-attack the SOD in open terrain.

I guess you do NOT have 20 or more catapults ready for the NE stack? And roughly the same of the second one?

Well, that is something I'd never do. Attacking someone's sub two turns before the player itself comes back.

(There is no rule against that, of course, but I wouldn't do that)

Anyway, my fault, as I never tried to contact one of them for a NAP (or contact anyone)

Whatever. I guess, both cities will fall (or if I see correctly they have fallen already)
Let's see how much damage I can do.

And I guess, the game will be decided on the other continent anyway.

So, the two cities fell, the units were gathered for some counter attack.

I had my stack sitting in between the two stacks that were coming closer, when the road under the stack got destroyed by a spy. Which meant, that I wasn't able to retreat with the stack to gather more units (and giving up another city)

So I attacked with that stack, almost killing nothing. (In the end it would have been better to just sit and let him waste his catapults, but it wouldn't have changed much because his units are superior)

Which now basically means game over for me...
