"Licence for Robert Aguillon and his heirs to enclose the manse of his manor (mansum manerii sui) of Percinges, co. Sussex, with a ditch and a wall of stone and lime and to fortify and crenellate it."
Granted at Westminster,
licensed 1264, 1268, 1329. King writes "Presumably the changes in government of this period give the reason for these extraordinarily cautious operations." Coulson cites the anxieties of the onset, hostilities and aftermath of the Barons' War of 1254-5 as a factor in the 1268 repeat.

(In fact, the original source given is usually a transcription/translation of what are precious medieval documents not readily availably. It should be noted that these transcription/translations often date to the nineteenth or early twentieth centuries and that unwitting bias of transcribers may affect the translation. Care should also be taken to avoid giving modern meaning to the medieval use of certain stock words and terms. Licentia is best translated as 'freedom to' not 'permission'.)
Significant later source are;
Robert Aguillon, (1226-1285) knight. Sheriff of Sussex. Steward of the Royal Household. Married Margaret, countess of the Isle of Wight.
Did the existence of his powerful and quarrelsome neighbour, William de Warenne, provoke the need for fortification. Robert had problem's with de Warenne's men in his lands in 1274, but well before this de Warenne had a reputation to being quick to violence. Equally his important royal positions and noble wife would be reason for asserting his social status.
