Lit. 'castle guard'; abbr. sometimes as warda. One of the duties owed by a tenant by way of his knight service, another of which, for example, was *equitatio. The knights of an *honour would have shared duties of castle guard; they might well have had the duty of guard at a king's castle such as Windsor. This latter would have arisen through their lord's *servitium debitum. However, as with *scutage, such duty could have been commuted to a money payment. -
