Do you mean the castle in the south with Big Bertha?
There are several guides available here for Stealing from the Rich.
The quote below is from my guide (click the little blue >> to get to it):

Camp 14) 50 Soldier Deserters, 50 Cavalry Deserters, 50 Longbowman Deserters, 1 Big Bertha
ANY general: [1: 176R 2: 200R (187R - 197R - 202R)]
ANY general: [1: 176R 2: 17R 183S (182R - 191R - 193R)]
VETERAN general: [140R 110S (100R - 124R - 140R)]

Like tage said, there are a couple of bosses in this game so it really depends on which way you are playing it.. There are plenty of guides on the forums in the adventure section please go and take a look. And I do prefer using tage/killste guides for stealing from the rich
