Houston, we have a problem.

The current status of my empire:
Stapel will attack me 8 turns from now. I was still busy building forges and grocers to get both my production and economy up to speed. The economy is doing fine now, since I completed the grocer in my holy city, and will complete a market in my capital next turn. Several forges are now also complete.
However, the cities that I conquered from Matrix and Robi are still mostly undeveloped, have low production (except Reeniville), and no barracks or stables. My own cities do have barracks for the most part, but only my capital has a stable. First, however, some intel on Stapel's army that I have, thanks to the wonders of religion:
His forces seem to consider of a mix of Axemen and War Elephants, with catapults as support units. Unfortunately, he researched Civil Service just a few turns ago, which means that he will probably upgrade those Axemen to Macemen. In response, I'll try to use Crossbowmen as my main defenders, supported by leftover Longbowmen. I can already build Macemen myself, so I will also use a few of these where possible. I'm also trying to build some Pikemen, which I sorely lack, and I have several Camel Archers that I might be able to use against Stapel's stacks to damage his artillery using flank attacks.
Here are my current civics. I just switched to Mercantilism (yay Spiritual trait!) because I'm not really trading with anyone and I can use the free specialists to boost production.
Also, you might notice that I've boosted research to speed up the discovery of Gunpowder. I'm not quite sure how much good it will do, but Musketmen are fairly good defenders, so it might help. After I've discovered it, I'll drop research to zero to help pay for unit upkeep and upgrades.
