Town battle
From MiddleWiki
A limited engagement melee battle involving one or more "buildings" and potentially the field that contains them. These buildings are often constructed from squares of hay bales. Usually there is a door opening and there may be one or more "windows".
Town battles are very similar in setup to castle battles in layout with the exception that the buildings are fully enclosed. In castle battles, the castle may not be fully enclosed.
The objective of the scenario may be last man standing, control of the majority of the buildings after a given time, etc.
