Western Franks & Normans

[Haardrada]

Hi Guys I have a question about this list that maybe you could help me with?

My concern is that I believe the end date of the list to be inacurate.In Italy/Sicily the fall of Palermo in 1072 marks the commencing date for book IV Sicilian list. This is ok for the army of Roger in Sicily as Roger was left with a few hundred knights and had to depend his Muslim & Greek subjects.While Robert Guiscard returned to Italy with some Muslim troops but in less amounts to those in the army in Sicily.,then on to Durazzo.
However, this army remained in Thessaly whith Behomund and Robert raised a new army to campaign against the Holy Roman Emperor from his Italian territories in 1084.After Roberts death his sons fought over his lands.Roger Borsa may have had access to Arab troops but Behomund raised his army in Norman Capua and had little or no access to Arab or Greek troops.Their war continued until Pope Urban II mediated by 1089 but was never ended until Behomund departed on the First Crusade. Therefore I suggest at least the Norman list should end in 1089. If anyone can expand on this feel free.
