She wrote that their arrival was preceded by plagues of locusts which was taken as a sign that the Kelts, as she often called them, would be as a plague to the Turks. It was quickly apparent that they would do more damage to the Christian Byzantine empire, which they attacked as often if not more than they attacked the Arabs.
She also blames much of their misfortune on their own arrogance. When Alexius told Peter to wait until the other counts arrive, Peter refused trusting in the numbers of his followers. She called the town where Peter was staying Helenopolis and not Cuiotte. She wrote that some 10,000 Normans broke off from the main group and attacked Nicaea (which was the headquarters of the Turkish Kilij Arslan) with particular cruelty. 'They cut babies to pieces, impaled some on spikes and roasted them over fires'. They tortured old people and returned to Helenopolis with booty. Then there were fights over the booty. So another group (Anna called them Normans but she often had trouble telling the foreigners apart) left for Xerigordon (Exerogogo). These were crushed by the Sultan. Kilij Arlsan then set a trap for the remainder sending spies in Helenopolis with the story that Nicaea had been taken and was being looted for all its gold. That made a crowd run out of Helenopolis to be slaughtered by the Turks. Considering that Peter complained in Gesta Francorum that his people would not listen to him, I think we can consider this a fact. Only Anna writes that Peter was with the handful of survivors that made it back to Helenopolis and that Alexis thought it would be a shame if the Sultan captured him and sent Constantine Euphorbenus Catacalon to rescue him and bring him back to Constantinople.
The Crusaders did not behave well in Constantinople, raiding Christian outskirts and rioting when Alexis granted them a 'market' as a courtesy. Small wonder that he took their weapons away when they returned. Some of the Crusaders were, as Anna says, opportunists and brigands who were not interested in liberating the Holy Land as much as they were interested in empire and booty. Okay enough from me and Anna, back to our story.
