 It purports to be the charter by which Æthelred granted 300 hides (about 36,000 acres) at Gloucester to King Osric of the Hwicce, and another 300 at Pershore to Osric's brother Oswald.It is preserved only as a copy in a 14th-century register of Gloucester, where it is followed by two charters listing the endowments made to the abbey until the reign of Link Burgred of Mercia (852-874).The 300 hides mentioned here are unlikely to be a contemporary detail, as they were intended to represent the triple hundred which later made up the area of Worcestershire.
