First, in the first world war of Sui and Chen, people's hearts were bought.
In the first month of the ninth year of Jian 'an (589), he divided his troops to cooperate with General Liu Renen's army and stormed Chen's camp on the shore. Lu led the army to resist according to risks and fought fiercely for more than forty times. Sui Jun suffered heavy casualties and more than 5,000 people died. In order to get credit and reward, Chen Jun cut off the nose of the deceased, which aroused Sui Jun's anger, fought to the death and won many times. All the captured soldiers Chen and Chen were released. Under the fierce attack, Lu was forced to abandon the camp gate and flee. Su Yang ordered his soldiers to destroy the chains of Lanjiang River and continue down the river. ?
Lu retreated to Jingmen Yanzhou (now in the middle of the Yangtze River near Zhijiang, Hubei Province), relying on the danger of Jingmen Mountain to deter again. Yang Su sent a thousand Bayan foot soldiers who were good at rowing. Take? Five teeth? Four warships, smashed more than ten Chen warships with poles, and captured more than 2,000 people. Lu's army was defeated again, and Lu escaped alone.
Second, the Sui army cooperated in many ways.
Chen Xinzhou, who was stationed in Anshu, Jiang Nanan, also abandoned the city and fled. Seeing that the situation was unfavorable, Chen Huiji, who was guarding the public security, burned her savings and led 30,000 troops and more than 1,000 warships to retreat eastward in an attempt to build health (now Nanjing), but was blocked by the king of Qin in Hankou (now the place where the Hanshui River in Hubei enters the Yangtze River). East of Baling, no one dares to keep it.
Chen Xiangzhou secretariat, Wang Yueyang Chen Shushen also fell to Su Yang. In this campaign, Su Yang and Liu Ren 'en cooperated with the water army and infantry to break Chen Jun's Jiang 'an stronghold first, and then joined the water army warships to crush the enemy. Sui large warships? Five teeth? The heavy racket equipment has shown its power in the battle. The policy of preferential treatment for prisoners has a positive effect on disintegrating the Chen army and cooperating with military strikes. At this point, the upper reaches of the Yangtze River were controlled by Sui Jun, which prevented Chen's army from helping the East and ensured the main force of the lower reaches to cross the river.
After Sui Jun won the battle of the upper reaches of the Yangtze River, Su Yang led the main force along the Yangtze River to the east, and joined forces with Yang Jun, the king of Qin, in Hankou (at that time, Sui Jun, the downstream, had already fallen to Jiankang), and at the same time, he sent troops south to expand the results.
In early February, Zhou Xue and Liu Renen were sent to attack Xiangzhou. Defeat Chen Xiangzhou who went out of the city to fight, help defend Chen, Fan and others, and capture Chen Shushen alive. Liu Ren 'en's army captured Wu Juye in Qiao Heng (now Changde, Hunan). The pacification of Xiangzhou and other places prepared a base for Sui to March into Lingnan.
