Last session ended in a rout. The cleric in the party really wanted to do something about the pack of ghouls they’d encountered while exploring a barrow. The party bought tons of oil and hired retainers to help them with the plan. They were going to liberally apply the oil, lure the ghouls, and spring the trap (lighting the oil on fire). When they got to the barrow, they completely abandoned the plan. 
When I checked for repopulation, some of the ghouls had moved out of the main room the PCs planned to attack. I don’t know if that’s what convinced them to abandon the plan, but they pretty much just charged into the room and attack the ghouls there. We’re doing OSE, and they’re a 1st level party against a couple of 2HD ghouls. They weakened one ghoul, but it got away to get reinforcements. They took down the other one, but then reinforcements started spilling from the rooms across the hall from where they were.
They made a valiant retreat, dragging about half their party with them (who were paralyzed). One of the retainers went down, and they proposed he could be the food you need to drop for OSE’s escape procedure. I rolled, and the ghouls went for it. I suppose it’s good the party managed to make it out with only the loss of the retainer, though people were banged up a bit (e.g., the cleric was at 1 hit point), but that could have gone a lot better.
