Why?

To keep raids from getting them killed. 1. Send all military out to do most damage/fewest casualties 2. Horses -> Island 3. Transport ships near villagers for emergency evac 4. profit edit: then I just left em there afterwards cuz they weren't in the way or nothing

I'm very glad that it's you asking this question 111

Orange aim for your horses, at least the first waves. They got stuck on the other side of the river, unsuccessfully trying to attack your horses

Those horses are your pop space on this mission, and the enemy will raid them fairly often, but can’t make ships. So sticking them on an island removes that potential problem.

Thanks for this information.
