As mentioned previously, Brennus declared on Sury. Not the brightest move as it turned out, but hey hoo, it's what the AI do.
Stalin popped the GM in Madrid and has a pile of gold, but very little available

A little later he would give us only 110 of 160g for Nationalism, so I sold it to him. Obviously close.
Brennus invades from the east, and Sury walks straight up to his isolated city (turns out it was an AP gift).
Time for WAAAAR! These are the stacks. The idea with the workers was kinda silly as I didn't get any real use out of them, but I thought it was a nice thought *shrug* For the zillionth time a city got founded. I wanted to march straight south for Coimbra, hence the bigger stack there, but we had to raze a brand new city first. In the east the stack is split up, but with more cannons for the bigger city south (I thought it had more than 20%).
Upon DOW Madrid is hauled right back into unhappiness (or very soon), with 4

from war weariness. We're going to need that Globe at some point, good idea, but I haven't done anything with it yet, as I reckoned we needed more units first. Have built 6 Rifles and then on to Cavs. Haven't cancelled the Iron deal, maybe a mistake, but I worry that 12 cannons isn't going to be all that much :-/
Have barely declared before Hattie gets Military Science and Grenadiers. The place will the swarming with them soon enough. Timing was good I think.
A little while later, and we're finally moving in on Coimbra. Due to the river there aren't any great tiles to attack from. Made some minor mistakes with movement here (like in the screenshot), but didn't get punished for it. Moved more units down from the north (healed for a turn), and we gather on the forested hill, before moving in for the kill.
The AI isn't always terribly wise in situations like this, but unfortunately Ragnar is quite gutsy, and threw several trebs into the stack, and then some Cuirs. Didn't notice it at first, but a damaged cannon from the previous attack actually died to flanking

Piles of units damaged too, but we didn't lose others. But it made things quite awkward, as the medic was on the other front. Two turns later I got down a fresh normal medic. It helped.
Meanwhile, in the east, Oporto is poorly defended. For the time being. Takes time to move with siege and rifle support, and Deity AIs sure can pump out the units fast (and Hatty is in caste).
Brennus' war on Sury wasn't the smartest move he's ever made. He loses the city, and looks like Sury took it at a canter. The worker continued south and checked out Sury's forces. Not much to brag about really. Didn't take pictures, but just a handful of Cuirs and longbows here and there. Apart from the stack that took Burgundian, he looks pretty weak. Have lost demographics view on him now, but we were up to about ~0.85 power ratio with him.
We killed a few solitary Cathy knights in the north, and here she pops up in Oporto. Turns out she's only passing through, and her real intention is to invade Madrid.
Next turn and the Sury vs Brennus war is put to an end. Oh, and yet another city is plumped down in the vacant land. This is certainly going to be an annoyance. Will the land these cities claim mean we can't cap people?
Finally it's time to attack Oporto. More guys in there now, but we get through okay

Hattie is hurting after that, and is willing to give us all her gold (albeit it's only 120g) and most of her gpt.
Well then, over to Coimbra in the west. It was so stuffed with units that I had to attack over two turns. Forgot to take a picture of the first batch, so this is only the last units. It went quite well really, but I did lose a Cavalry at 98% odds

The cannons survived, though, which is the main thing.
Oh yeah, and heeeeeeeeeeeeeeeere's Cathy!
We're not in real danger I think, but it's certainly a nuisance. Not least because she could pretty easily smash our horses. If that happens we could probably use some more cannons. It feels a bit short, and requires more time healing than I'm used to from normal games.
