If you decide to sneak into the castle unnoticed, then this is the best place to do it. In this part of the fortifications, the guards rarely pass and even less often stop to look around. Hide behind trees, rocks and grass. Choose the best moment to climb the wall. Be very quiet, the garrison sleeps in these houses. Poison their food and water and return. Or you can try to move on to the barbican and open the gate.
