Robert Knolles

Sir Robert Knolles or Knollys (c. 1325 – 15 August 1407; aged 81–82) was an English knight of the Hundred Years' War, who, operating with the tacit support of the crown, succeeded in taking the only two major French cities, other than Calais and Poitiers, to fall to Edward III. His methods, however, earned him infamy as a freebooter and a ravager: the ruined gables of burned buildings came to be known as "Knollys' mitres".
