Next scenario up for solitaire play is Zama. Below is the initial deployment.
The diagram below depicts the situation at the start of the Carthaginian turn. The Roman horse with leader faces a Carthaginian warband with leader.
Carthage plays a 'three unit right' card and moves the light infantry two hexes to block the left rear retreat hex for the Roman while the warband moves two hexes to cut the right rear retreat hex.
The Carthaginian medium infantry moves adjacent to the Roman horse taking the position vacated by the warband.
With Roman escape blocked, the warband attacks since it must Close Combat having moved two hexes. The Roman horse took one hit and two flags and was forced to retreat. With no retreat, the horse was destroyed. The leader, alone in the hex, was killed on a single roll of 'helmet.'
After making this move, I wondered if this encircling tactic could be justified on the ancient battlefield. Should enemy units project a ZOC that would stop such penetrations or is this attack deserving for those units finding themselves over-extended?
