Subsequently, the National Government, in the name of Grand Marshal Chiang Kai-shek, formally issued the first, second, and third instructions of the base camp, and on the basis of the two sets of operational plans formulated at the beginning of the year, successively issued a series of operational guidance instructions, requiring all troops to "follow and implement them on the basis of the two sets of operational plans formulated at the beginning of the year.":
First Theater: "The enemy who should be confronted in the near future shall carry out a soft attack in order to attract his main force and allow the operations of our second and third theaters to be carried out calmly." But if the enemy tries to fight me in a decisive battle with its true face, it should resolutely do its best to prevent it. ”
Second Theater of Operations: "Break the enemy's usual attempt to encircle the enemy, so that it does not dare to carry out a frontal attack on our first theater, and at the same time contain the enemy army east of the Rehe River, so that its operations against Qingdao and Songhu cannot be diverted to strength." ”
Third Theater of Operations: "The enemy in Songhu, the army and navy and its air force land base areas are now invaded, and swept and extinguished in preparation for the enemy's response when it comes again." At the same time, for the areas along the coast of Zhejiang where the enemy can land, they will quickly form stronghold-type positions to prevent the enemy from landing or take the opportunity to annihilate them. ”
Fourth Theater of Operations: "In addition to disturbing the enemy's land, sea and air and completing the combat readiness posture, full preparations should be made to participate in the second phase of the operation." ”
Fifth Theater of Operations: "The characteristics of operations in this theater are operations against the enemy's forced landings, so they take the initiative, take advantage of the pre-emptive advantage, and fundamentally break the enemy's attempt to land. Even if one of the enemy troops lands first, it must be quickly besieged and annihilated, so that the follow-up corps will not be used as a cover for a safe landing. This is the second essence of operational guidance. When necessary, it is necessary to hold firm within the designated area, absolutely limit the progress of the enemy army, and use mobile troops to annihilate it, so as to ensure the centrality of the operational company of our army in the north and south of the battlefield. ”
Navy: "While the Songhu side is engaged in war, it is necessary to block the Wusong Pass, destroy the enemy ships within the Wusong Pass, and absolutely prevent them from passing through the west of Jiangyin, and cooperate with the fortresses and land forces." ”
Air Force: "The Air Force should concentrate its main forces in coordination with the Army to annihilate the enemy in Songhu first (with enemy ships and artillery as the main targets), and then assign another task." ”
