Well the whole "cattle" thing.
One of the looting options is to kill livestock or something like that. The Caglian Empire and allies are attacking Sale with a... ~40k CS force, but like most looting options, each unit only kills so many cattle. The Barony of Makar with its ~3k CS force can't really defend, so it works out to truly look like CE & Co. vs. a bunch of cows... Resilient cows, apparently.
It's even funnier to me because Sale is a city, so there really wouldn't be fields with cows... They'd either have to be close to the walls (in which case, that's pathetic for a 40k CS force) or inside the city (penned up and not particularly challenging). Reminds me a lot of this:
