I actually have 21 gold to spare. Metamagic mana from the new nodes didn't show up until I left and rejoined the game.
Here's the situation at Saltus. It's grim.
In one of the all-time

moves, I have one of my two promotable adepts sitting in the city. I'm not even sure how that happened - probably I was trying to move in a puppet and had the wrong unit selected. In another dumb move, I sent out what I thought was a 3-move swordsman to kill a barb warrior at the "3 moves" sign at the bottom of the picture. He turned out to be a two move unit, and is stranded outside the city. I should have just left the barb there; he would have done us a favor by pillaging the road. I also attacked a warrior just west of Saltus. That one is somewhat more justified: I didn't want him removing the Stoneskin promotion from my Freak. Anyway,

We have no prayer of holding this city, and now they'll be on our road network. I think it's best to leave my units in the city, to force them to use as many catapults as possible. It might be best to move out your chariots, though. They can hit both of your mud golems on the jungle tiles.
Edit: I checked techs, and they went for Animal Handling instead of Feudalism. For hawks, presumably. I guess I'm in no position to question their strategy for this game

.
Edit2: I didn't end turn yet.
