Alexios planned to attack Guiscard's camp; Guiscard moved his army & drew it up for battle

Summary:
Alexios I planned to assault Robert Guiscard's camp from two sides: all his non-Christian troops were to attack via salt-pans in the rear, while he would lead a frontal assault once he knew the others had arrived. However Guiscard left his camp empty, crossed a bridge and reached Hagios Theodoros, where his men took communion. Then he drew his forces up in three parts: he led the centre, Amicus of Molfetta the seaward wing and Bohemond the landward. When Guiscard moved his army, Alexios quickly redirected his own troops to Robert's new position, giving a special role to the Varangians under Nampites, but allowing the attack from the rear on Robert's camp to continue. In drawing up his army, he led the centre, while he put Nikephoros Melissenos in charge of the right wing and Gregorios Pakourianos of the left; Nampites with the Varangians was positioned in front of the centre with a corps of archers
