3 Sakha - Late present Confident Expert 1632 CE 1642 CE
Tokarev and Gurvich mention fortifications surrounded by water and snow: "When speaking of structures, we should also mention the fact that in the old days the Yakuts knew how to make fortifications or ostrozhki, as they were called in the Russian texts of the 17th century. For example, in 1636-1637, during the campaign against the Kangalastsy, the Russian Cossacks found that “they had built strong forts with two walls covered with gravel, and surrounded by snow and water;” it was only after a two-day assault that the Cossacks managed to take one of these forts. In 1642 the Russians also took a Yakut fortress after great difficulty: “. . . the fort was made with two walls, the space between the walls was filled with earth, and there were log towers.” At a later stage these fortifications disappeared, and no one has described them since in detail. But even in the 19th century it was possible to find special tower-like barns here and there, which belonged to the Toyons." [1]

In the Guchengzhai site, "The moat, which used water from the Qinshui river, was another important defensive barrier around the site. Its width ranges from 34m to 90 m. Coring/probing (zuantan 钻探) determined that the now buried moat is over 4.5m deep in the eastern section, but the river bed is still visible today." [1] "Haojiatai, whose walled enclosure covers an area of 6.5 ha, is also built on an elevated platform and is further protected by an external ditch, most likely a defensive moat." [2] "Some of the walled settlements have surrounding ditches that may have served as moats. One of the functions of the walls probably was defense." [3]

218 Northern Song present Confident Expert -
City walls usually protected by a moat. [1] "When Jin forces attacked the Song capital of Kaifeng in 1126, they met stout resistance. The city’s defenses had been overhauled, and it boasted immense walls, a deep wide moat, and advanced fortifications structures including bastions and barbicans." [2] "In the late-tenth and very beginning of the eleventh century, the Song dynasty (960-1279) undertook a large-scale defensive project to protect its northeast border. ... the Song government gradually constructed a continuous band of water obstacles, spanning hundreds of miles across northern Hebei province from the Taihang Mountains ... in the west to the Gulf of Bohai in the east. The spine of these obstacles was a dike that connected its surrounding rivers and swamps into a continuous defense line. Unlike the Great Wall, the role of which was miniscule, this Great Ditch played a large part in stabilizing the military situation between the Song and Liao, leading to the Chanyuan Covenant (Chanyuan zhi meng) in 1005, and a peace that lasted for more than a century."
