The siege of Suiyang was a military campaign during the An Lushan rebellion, launched by the rebel Yan army to capture the city of Suiyang from forces loyal to the Tang dynasty. Although the battle was ultimately won by the Yan army, it suffered major attrition of manpower and time. The battle was noted for the Tang army's determination to fight to the last man, as well as the large-scale cannibalism that occurred during the siege.
