This predatory expedition is related by Froissard (Chronique, tom. i. p. 230), and in the life of Du Guesclin (Collection Generale des Memoires Historiques, tom. iv. c. 16, p. 107-113). As early as the year 1361, the court of Avignon had been molested by similar freebooters, who afterwards passed the Alps (Memoires sur Petrarque, tom. iii. p. 563-569).
