After the establishment of the Southern Song Dynasty,the people of the Song Dynasty were always faced with war.Because of the frequent wars,the government of the South Song Dynasty gradually formed three war zones in the areas of Huaihe,Jinghu and Sichuan to deal with the wars.The Jinghu area is located in the middle of the three war zones,and its position is very important.In the period of emperor Li Zong of Song Dynasty,This region had developed into a system of joint operations.Local military officers were in charge of military operations and logistics officers dispatched by the central government were responsible for military logistics.Based on the specific changes of the national defense deployment and the logistics supply of the previous generals,this paper combs the development process of the national defense construction in the whole Jinghu area during the Li Zong period,and analyzes the influence of the two groups on the stability of the Jinghu area in different periods and the final survival of the Southern Song Dynasty from the perspective of the contradiction of military supplies between the two groups.Li Zong period was a period of dramatic changes in the national defense deployment and logistics supply of the whole Jinghu area,which was mainly divided into two stages.The first stage was the period from Chen Gai to Meng Gong.This stage was divided into two development periods.The first was the strengthening and final collapse of the national defense deployment since Zhao Fang,this period mainly occurred from Chen Min to Shi Songzhi because of the Southern Song government’s wrong orders,The defense line of Jinghu area collapsed.There was the period of national defense reconstruction in Jinghu area,which was mainly the period of Meng Gong.During his term of office,Meng Gong rebuilt the national defense line of Jinghu area and moved the army to the south.The officials in charge of military logistics also had different performances.During the period from Chen Min to Shi Song,the logistics officers also changed from disaster areas to timely support the army logistics.But in Meng Gong period,the contradiction between Quartermaster and commander appeared again,Because of the collapse of the national defense line in Jinghu area at that time,Meng Gong increased the demand for military logistics supply.At that time,Zhu Jian,a quartermaster officer,tried his best to support logistics despite his own difficulties.They had effectively cooperated and stabilized the situation in the Jinghu area.The second stage was from Jia Sidao to Lv Wende.This stage is divided into two periods.The first stage was the period from Jia Sidao to Li zengbo.During this period,the large-scale war in the Jinghu area stopped temporarily,and Jia Sidao continued his recuperation policy.There were two changes during the period of Li Zengbo,Li Zengbo moved his army northward to Xiangyang again,the second was that the Central Government recovered the tea tax revenue that should belong to the logistics officers,this not only led to the decline of the logistics supply ability of the commander in chief,but also restricted the combat ability of the army.From Wuyuan to Lv Wende,the continuous decline of logistics supply capacity in this period led to Lv Wende’s indirect trade with the enemy,which led to the siege and collapse of Xiangfan.And eventually led to the demise of the Southern Song Dynasty.Finally,no matter Xiangyang or Jiangling as the core of national defense,and the efforts of commanders and logistics officers in different periods,they could not avoid the final demise of the Southern Song Dynasty caused by the fragile logistics supply capacity. |
