Harold's forces deployed in a small, dense formation at the top of steep slope, with their flanks protected by woods and marshy ground in front of them. The line may have extended far enough to be anchored on a nearby stream. The English formed a shield wall, with the front ranks holding their shields close together or even overlapping to provide protection from attack. Sources differ on the exact site that the English fought on: some sources state the site of the abbey, but some newer sources suggest it was Caldbec Hill.
