Why are you not building units? Chariots to help take hill city? Crossbowman too. Mace would of been good against his UU/catapults and to attack cities.. He will be spamming his UU now. If he has catapults he will form a stack with both. .Your Catapults wil l suffer with his UU flanking. He has 2 lots of horse so harder to pillage. Not a big fan of windmills this early. Your killing a 1f3h tiles for a 2f1H1c tile. Each new citizen consumes 2f. Sparta was a very nice production city but you are now gradaully making it average. With civil service you can farm that cottage for extra food.
