Strength 2 Impi win against cats. Impi is 35, Cat is 50. Alternative is sacrificing a cat against combat 2 Impi or an Axe on a hill, and defend with 3 cats more. Too expensive. I am not worried about surviving, I am worried about war being too expensive without metal units. Gifting a city on a hill makes Willem survive, gets us 3 free units, and, also, a diplo bonus if Amsterdam miraculously survives and we decide to take it out. I'd rather not do that, though. Mansa or Lizzy will get Alpha soon, hopefully. Letting Willem die before getting hints is no option for me.
