Battle of Hanshan In 547, Yang Kan was summoned back to the capital to serve as a Palace Attendant. At the time, the Eastern Wei general,
Hou Jing rebelled in the
Henan and called upon the Liang to support him. Emperor Wu issued another northern expedition, and Yang was made Champion General and tasked with building a
weir at Hanshan (寒山; in present-day
Xuzhou,
Jiangsu). After completing the weir, he advised his commander,
Xiao Yuanming to flood the enemy city of
Pengcheng, but was ignored. When Eastern Wei reinforcements led by
Murong Shaozong arrived, Yang Kan repeatedly urged Xiao to attack him, but was rejected each time. In the end, Yang brought his soldiers to camp at the newly built weir. In November or December, the main Liang force was defeated, so Yang ordered his men into battle formation and slowly withdrew.
Siege of Jiankang When Yang Kan returned in 548, he was once again appointed Director of the Justice Department of the Imperial Secretariat. Meanwhile, Hou Jing was defeated in Henan and formally surrendered to the Liang. However, he soon rebelled and captured
Liyang. When asked by Emperor Wu for countermeasures, Yang said, "Hou Jing had long been planning to rebel and is making haste towards the capital. We should swiftly occupy
Caishi and order the Prince of Shaoling (Xiao Lun (蕭綸)) to attack
Shouchun. Hou Jing will be unable to advance, and if he retreats, he will be without a nest, and his forces will soon dissipate." The officials in
Jiankang did not believe that Hou Jing would attack their city. Instead, they ordered Yang to lead more than 1,000 cavalrymen to camp at Wangguo Gate (望國門). As Yang Kan predicted, Hou Jing continued south towards Jiankang and reached Xinlin (新林; southwest of present-day
Nanjing,
Jiangsu). When Hou Jing rebelled, the lands of Liang had been at peace for nearly five decades that even many of the officials and scholars in the countrysides do not have experience in war. By then, many of the old generals in the capital were dead, while the new generals were all stationed outside. The only generals in Jiankang aside from Yang Kan were Liu Jin (柳津), who was old and sickly, and Wei An (韋黯), who was considered cowardly and incompetent. Therefore, the imperial court sent people to fetch Yang Kan and ask him to assist the Crown Prince,
Xiao Daqi to command the capital's army. With Hou Jing's arrival coming as a surprise, there was great disorder in the capital as many people rushed in to take refuge. Yang Kan divided the city into areas of defence and had the royal family participate in the fight. He also issued for any soldiers caught stealing weapons from the armoury to be executed, thus restoring order in the city. When Hou Jing approached the capital, the people were frightened, but Yang falsely claimed that he had received an arrow with a letter stating that reinforcements were coming, which slightly calmed them down. The rebels set fire to the Eastern Ye Gate (東掖門), but Yang put it out with water and killed several of the rebels with his bow, driving them back. Emperor Wu promoted Yang Kan to a Palace Attendant and Military Adviser-General. He also wanted to gift him a large sum of gold, silver and silk for him to reward his soldiers, but Yang refused, using his own wealth to award them instead. The rebels then built a "pointed wooden donkey" to attack the city, which the defenders were unable to counter it. Yang Kan made a pheasant tail torch, installing an iron arrowhead doused in oil and fired it at the wooden donkey, burning it completely. The rebels also built earthen mounds on the east and west sides of the city, but Yang sent people to dig tunnels below the mounds, causing them to collapse. Other than that, the rebels made a tower cart that was around ten
zhang tall, intending to shoot arrows into the city from it. However, Yang observed that the tower was too high and that the city moat was still shallow, so they will not need to deal with it. As he anticipated, when the cart started moving, it immediately fell. Unable to break through, Hou Jing decided to make long siege lines to surround Jiankang. Emperor Wu's advisors,
Zhu Yi and Zhang Wen (張綰), suggested they sally out and attack the lines. Yang Kan disagreed, stating that sending out too few soldiers will not yield success, but sending out too many soldiers and failing, due to the narrow gates and small bridges, will result in a crush when they withdraw back into the city, hence causing heavier casualties. However, Emperor Wu did not listen to Yang, and sent over a thousand soldiers to fight. Before they could even engage, the Liang soldiers retreated, and indeed, as they were scrambling across the bridge, many of them fell into the water, with most of them dying. During the siege, Yang Kan's eldest son, Yang Zhuo (羊鷟) was captured by the rebels. Hou Jing brought Yang Zhuo to the city to coerce his father into surrendering. When Yang Kan saw him, he said, "I have sacrifice my whole clan just to serve the lord, and it still does not suffice. Why would I care about a single son?" Hou Jing returned with Yang Zhuo a few days later, but Yang Kan remained persistent, saying to his son, "I thought you dead for a long time, so how are you still alive? I have pledged my life to my state and swore to die in battle. I will not falter because of you." He then shot Yang Zhuo with a bow. Hou Jing was moved by his show and loyalty, so he did not kill Yang Zhuo. Hou Jing later sent the official, Fu Shizhe (傅士哲) to speak with Yang Kan, telling him, "King Hou had come from afar to pay his respects to the emperor, so why are you closed off and denying him his tribute? As a minister of state, you should be opening the court." Yang angrily refuted, "Since General Hou's surrender, the court had place great trust and expectations onto him. What grievance could have caused him to suddenly rise up in arms? Is this the behaviour of a minister? I will not fall for your honeyed words and open the door to thieves." Before leaving, Fu Shizhe, who admired Yang, requested to see him without his military armour. Yang removed his helmet, and Fu Shizhe left after staring at his face for some time. Later, heavy rain caused the earth hills within the city to collapse. The rebels took the opportunity to attack the city, and the defenders were unable to stop them. Yang Kan ordered his soldiers to throw their torches and burn the city to slow the rebels down. He then slowly built a new wall within the city to prevent the enemy advance.
Death and posthumous honours In January 549, Yang Kan fell ill and soon died in the city palace at the age of 54. Emperor Wu posthumously appointed him a Palace Attendant, General Who Protects the Army. He was also awarded with "Secret Objects of the Eastern Garden" (東園祕器) and a troupe of musicians. While reinforcements under the Prince of Shaoling, Xiao Lun and
Liu Zhongli soon arrived, they were defeated by Hou Jing, and Jiankang and Emperor Wu were both captured by the rebels later that year. After the fall of Jiankang, Hou Jing made Yang Kan's daughter his concubine. One of his sons, Yang Kun (羊鵾), surrendered to Hou Jing, but in 552, he assassinated Hou on his ship and returned to Liang, thus ending the rebellion. == Anecdotes ==
