Hi again, Mr. Cornwell. When the Danes or Saxons formed a shield wall, how did they protect their flanks? Was it an unspoken rule that you only attacked the shield wall head-on? Or did they refuse battle until they found natural features of the ground like marshes and woods to anchor their flanks on? I would think that an attack on the right, with the enemy’s shield arms facing the wrong way could be quite devastating. Alan Kempner
