Fallen Outpost is a minor Mongol camp southwest of Cloud Pass, right on the Komatsu and Tsutsu border. It was once a Clan Adachi post, and clearing it pays steel and stance progress.
The main gate is on the south side, with a gap in the wall to the north. A lookout tower guards the bridge into the camp. Inside are three barracks and storage buildings, a stable and more towers.
A siege weapon sits outside, showing how the Mongols broke in. Bonus goals can include staggering spearmen with Wind Stance heavies, headshots and killing burning enemies.
