I would appreciate any help on this . . .

I'm at the part of the game where you are roaming around a town filled with german winter troops. You have to get in a fenced in Guard post and blow up a couple of tents.

I got in, blew up the tents, but the next task is to escape on the South side of town through the commandants office.

No matter where I go, I can't find a way out. There is one way you go where there are tons of troops, so I figure this must be it since it was so heavily guarded. I kill all the troops and there is no exit.

Anyone know where the exit is?
