We can easily test this by comparing Anglo-Saxon history with Norman of the same period, after castles had arisen in Normandy. Who among Saxon nobles was more likely to possess a castle than the powerful Earl Godwin, and his independent sons? Yet when Godwin left the court of Edward the Confessor, because he would not obey the king's order to punish the men of Dover for insulting Count Eustace of Boulogne, we do not hear that he retired to his castle, or that his sons fortified their castles against the king; we only hear that they met together at Beverstone (a place where there was no castle before the 14th century)[51] and "arrayed themselves resolutely."[52] Neither do we hear of any castle belonging to the powerful Earl Siward of Northumbria, or Leofric, Earl of Mercia. And when Godwin returned triumphantly to England in 1052 we do not hear of any castles being restored to him. Now let us contrast this piece of English history, as told by the _Anglo-Saxon Chronicle_, with the Norman history of about the same period, the history of the rebellion of the Norman nobles against their young duke, William the Bastard. The first thing the nobles do is to put their castles into a state of defence. William has to take refuge in the castle of a faithful vassal, Hubert of Rye, until he can safely reach his own castle of Falaise. After the victory of Val-ès-Dunes, William had to reduce the castles which still held out, and then to order the destruction of all the castles which had been erected against him.[53] Or let us contrast the _Anglo-Saxon Chronicle_ of 1051 with that of 1088, when certain Norman barons and bishops in England conspired against the new king, William Rufus. The first thing told us is that each of the head conspirators "went to his castle, and manned it and victualled it." Then Bishop Geoffrey makes Bristol Castle the base of a series of plundering raids. Bishop Wulfstan, on the other hand, aids the cause of William by preventing an attempt of the rebels on the castle of Worcester. Roger Bigod throws himself into Norwich Castle, and harries the shire; Bishop Odo brings the plunder of Kent into his castle of Rochester. Finally the king's cause wins the day through the taking of the castles of Tonbridge, Pevensey, Rochester, and Durham.
