More is known about the Norman deployment. Duke William appears to have arranged his forces in three groups, or "battles", which roughly corresponded to their origins. The left units were the Bretons, along with those from Anjou, Poitou and Maine. This division was led by Alan the Red, a relative of the Breton count. The centre was held by the Normans, under the direct command of the duke and with many of his relatives and kinsmen grouped around the ducal party. The final division, on the right, consisted of the Frenchmen, along with some men from Picardy, Boulogne, and Flanders. The right was commanded by William fitzOsbern and Count Eustace II of Boulogne. The front lines were made up of archers, with a line of foot soldiers armed with spears behind. There were probably a few crossbowmen and slingers in with the archers. The cavalry was held in reserve, and a small group of clergymen and servants situated at the base of Telham Hill was not expected to take part in the fighting.
