How to Achieve Hot & Spicy?

Hi guys,

I'm doing a campaign playthrough and I'm on the third mission, Quetzlcoatl, where you need to face down the Tlaxcala and Cortes.

There's an achievement in Steam that unlocks if you clear the mission without letting Tabasco be defeated, called "Hot and Spicy". However, I haven't seen any success trying to unlock it. They always send a small force that includes a Battering Ram. I've managed to pick off the ram by sending 5 eagle scouts to pick it off, and that buys me maybe a couple extra minutes, but then the cannon galleons blow up the TC and Tabasco resigns.

The longest I've managed to make it in was maybe like 20 minutes because for some reason the Cannon Galleons didn't attack the TC immediately, but in the end it was destroyed anyway. :(

Sometimes if I engage too early with my eagle scouts the cannon galleons will aggro early and just wipe the TC and there's nothing I can do. But if I don't engage at all the battering ram gets it.

Playing this on hard difficulty, do you think it's even possible? The level is cake if I don't save Tabasco, but I want to unlock the campaign achievements on hard. I've also seen in the past that at the 15 minute mark or so Tabasco literally just implodes. I haven't seen that happen in DE yet but if it did that would basically make this unachieveable.

Any ideas?

EDIT: Success! Got it on video too. I ended up rushing 2 villagers there, building a monastery, and then converting their cannon galleons.
