The Preceptory prospered for around two hundred years until 1309 when the Templars were suppressed. William de la Fenne was Westerdale's last preceptor and it is likely that with their impending suppression, he encouraged his Templars to turn much of their valuable goods into cash. A listing of their removable possessions is surprisingly small, particularly in the light of us being told that Westerdale had been declared the 'head Preceptory of North Yorkshire'. The granary contained only 4 bushels (100 kg) of rye.
