Besieged city with three (3) troops.

Apparently, the AI suffers from "fog of war" too.

I had some cavalry fragments -- 1 HA and 2 merc cav -- left over, and sent them to besiege a town. When they're counter-attacked, I could just withdraw them. That way, they could impede the army that was in the town.

Lo and behold, the much larger enemy army did nothing.

The second turn, I sent some infantry to reinforce. The siege lasted another turn.

In all, it was three turns before the enemy army realized the weakness of the siege and drove them off. In the meantime, the port city lost a bunch of revenue, I presume.

I tried doing that once with Two units of Militia Cav

they sallied and I withdrew after throwing all my javs without losing a man - then lost all my Militia Cav to that lovely "Withdraw from siege and lose all your units" Feature.

Whether or not a unit disbands after a siege is broken must have something to do with morale. I never lose mercenaries. I just completed a battle against the Seleucids, though, where ALL of their militia cav disappeared even though they got off the battlefield unscratched.
