Emergency Evacuation

At the end of the battle, count the number of
units you have remaining (including embarked
units). Divide that number in half and round up
to 4 if the result was less than 4. This is your
target. For each unit that is wholly within 6 of
the center of the battlefield roll a d6 (-1 if battle-
shocked). On a 4+ it succeeds and you must
have at least 4 successes to score.
