The siege of Exeter occurred early in 1068 when King William I of England marched a combined army of Normans and loyal Englishmen westwards to force the submission of the city of Exeter in Devon, a stronghold of Anglo-Saxon resistance against Norman rule following the Norman Conquest of England. After a siege lasting eighteen days, the city surrendered to William under generous terms and allowed the Normans to consolidate their hold over the West Country.
