That rule states, "...a unit that retreats onto its baseline row of hexes and still has additional retreat movement to be completed, instead of losing one block for each retreat hex still remaining in the unit’s retreat, the unit is instead eliminated....":strip_icc()/pic9068335.jpg)
Tough day to be a Turcopole
(RB) Perhaps the best answer on how to resolve this issue can be found in the Commands & Colors Medieval rule booklet on page 14.
"When a unit can retreat legally, toward its controlling player’s baseline, without taking block losses, it must take this retreat path instead of a retreat path where a block loss would occur."
(RB) The retreat path in the above example to the left is the correct retreat path that must be taken... resulting in eliminating the unit.
"When a unit cannot retreat because its retreat path is occupied by units (regardless if friend or foe), an enemy Leader that is alone in a hex, or it is forced to retreat off the battlefield or onto a hex that has impassable terrain, one block must be removed from the unit for each hex of the mandated retreat movement that the unit cannot fulfill."
(RB) Because the Turcopole Light Cavalry unit must retreat 4 hexes, even if the unit had no other retreat path possible and only the retreat path to take was the example to the right, the unit would still be eliminated having to complete a 4 hex retreat so there would be no Panic roll...
