A Unit that fails the test [cohesion] is disordered and loses a number of VBU equal to the difference between the number rolled on the dice and the Critical Number. If a Unit’s VBU drops to 0 or less then the Unit is Routed and is immediately removed from the table. […] A Unit… that is Disordered a second time while passing the Cohesion Test caused by receiving fire [or from damage in a mêlée] also takes a permanent loss to their VBU.
The Persians had their cavalry strong in the centre and their left, with a few light horse archers on their right.
We advanced boldly, at first… those blokes in armour on heavy horses all shoot!! Fortunately for me, Stephen Y’s firing dice were not performing well.
I sent my equites against Stephen Y’s cataphracts. A slightly ‘crazy’ move, not helped by me erroneously allowing him support units in both mêlées, so that one of his units was able to be a main and support unit—silly me. It was the VBU thing, my confidence and concentration were ‘shot’…!! :)
