I also found this write-up from a game blogged last year of the same battle by George Armold at Lone Warrior HERE.
Arnold's seems a bit pedestrian but he seems to get a result without much pain.
The Ilkley version is more colourful and complex but seems to have been less smooth.
Would be nice to find out more about Arnold's 'Classis' rules - even if hexes are not my cup of tea.
