The title and associated estates passed to his son William de Ufford. It was in or shortly before 1380 that, having been withdrawn from the ravages of the sea, the entire newly built monastery apart from its church was destroyed by fire, together with their corn and other goods. (Traces of this may be represented by areas of reddening in the surviving fabric.) The Abbot and convent were obliged to petition for a writ of "supersedeas" for distraint of the tenth, being thrown completely into debt and deprived of subsistence, and were granted this relief. Whether this fire was a harbinger of the Peasants' Revolt in East Anglia in 1381, or the result of accidental causes, is not reported. William de Ufford was certainly vigorous in suppressing that destructive uprising, but died suddenly without heir in 1382 and was buried at Campsey Priory. In the wake of the fire the last major rebuilding took place: the Earl's will, written 12 June 1381, left 500 marks to Leiston Abbey.
