For reasons that remain unclear, King Edward III exempted the men and tenants of the manor of Plumstead from providing four men from the borough for the sheriff as was the requirement elsewhere. A writ to Roger de Reynham, Sheriff of Kent in 1332 directed and commanded him that the residents of Plumstead should be allowed to send one man only. By 1363 Edward also decreed to the monastery in his charter of infpeximus that he released all manors and possessions given to it by former kings, including William the Conqueror. He also confirmed all the grants of liberties previously bestowed on the abbot and monastery.
