The vermin forces attacked the front gates while you were positioning your archers. There were heavy loses.

Your remaining forces are:
150 Archers
20 Spear Handlers
50 Sling Shooters
25 Sword and Staff Combattants
250 Utility Soldiers
35 Medics and Supply Officers (All of whom are treating injured troops.)

You have to make a snap decision:
Divide troops evenly at each location.
OR
Continue Positioning each force separately.
