This mission will require you to split your forces to attack four different exits that the thieves can use to escape. Don't immediately go after the thieves that have items, or you will be hard-pressed to catch them before they escape. They move on turn 4 enemy phase. Take out the four enemy bandit leaders first before worrying too much about the ones that will drop items.
Each of the four bandit leaders will be equipped with an Iron Shield, which the player could optionally steal, but it is likely that the player will have access to Steel Shields at this point, so it isn't really necessary.
When engaging any enemy unit in this Paralogue, make sure to kill it quickly, as it will run for one of the exits upon taking any damage. The bandit leaders will not flee, though.
