The Siege of Tintagel occurred in 1066 when the Norman nobleman William FitzOsbern led a 1,532-strong army to besiege the major English city of Tintagel, Cornwall amid the Norman conquest of England. FitzOsbern swept through Cornwall as Robert of Mortain subdued the main villages in the region, with Robert defeating Saebbi's Anglo-Saxon counterattack against Athelney. FitzOsbern's 1,532-strong army besieged the 1,020-strong English garrison of Tintagel, and, after building several siege engines, FitzOsbern assaulted the city and captured it with 251 losses. Tintagel's fall was followed by the Norman occupation of Axebridge and Bath, and South West England was soon subdued by the Normans.
