And since a fort will only keep your troops fed for 4 turns there's a good chance that the enemy will just wait it out. If they could be upgraded to have better walls, forts might become a bit more useful. As it stands, I only use them for the purpose of slowing down approaching armies (manning them with cheap, expendable units) to buy time for myself to make preparations.
I sometimes use forts so that emeny can't immenditally attack my forces. So that way I can give reinfrocements some time.
