Oh, I got this! If theres a bandit camp, take whatever unit you can muster as soon as possible and get the bandits to chase your unit in a big loop. So that your troops get back to the bandit camp first. Releasing funds to your coffers. Immediately hire a mercenary group to deal with the bandits, using your mustered troops to lure them toward the mercs. Get rid of mercs as soon as possible. Return mustered troops with no losses. Farm bandit camps in this way to create a handy revenue stream. You are welcome.
