Stronghold Crusader

Hold Enemies Captive Inside Their Own Castles

Take a small building such as an Oxen Tether. Place 1 or 2 of them
right outside the gatehouse(s) of your enemy's castle, but make
sure their keep is enclosed first. Immediately put the Oxen
Tethers to sleep. The ground troops will walk to the gatehouse to
destroy them but they can't get through, so they just walk back to
their spot. Your enemy's buildings outside of the castle will
spontaneously crumble because the workers can't get back inside
the castle. Also, the gatehouse(s) you blocked might spontaneously
crumble after a while. Soon there will be no food and the peasants
will leave the castle. The small army will be trapped inside their
own walls awaiting your arrival. When your army is built up, you
can just waltz over and wipe the whole castle off the map. (Note:
Make sure there are no enemies outside of the castle, or else they
will probably come and destroy your oxen tethers.)
