“ Among the Norman prisoners Suger (283 A) counts “Paganum de Gisortio, qui castrum idem primo munivit.” Orderic (766 C) gives him, like several other people, a double name; he appears as “Tedbaldus-Paganus de Gisortis.” This first fortification of Gisors must be that which is referred to by Robert of Torigny under the year 1096; “Rex Willermus fecit quoddam castellum, Gisorth videlicet, in confinio Normanniæ et Franciæ.” See below, p. 190. ”
