On this day 89 years ago, October 7, 1936 (August 22, 1936 in the lunar calendar), the three main forces of the Red Army successfully met and the Long March ended. On October 7 and 8, 1936, the vanguard of the Red Fourth Front Army met with the Red First Front Army troops who came to meet them in Huining, Gansu Province. On the 9th, Zhang Guotao, Zhu De, Xu Qianqian, and Chen Haochang led the Red Fourth Front Army headquarters to Huining and joined the Red First Front Army. At this time, the Red Fourth Front Army had more than 30,000 people. The Long March of the Red Fourth Front Army lasted a year and a half, and it had crossed the grassland three times and experienced hardships and twists. On October 21, He Long, Ren Bishi, Guan Xiangying, and Liu Bocheng met with Zuo Quan and Political Commissar Nie Rongzhen, acting commander of the Red Army, in Pingduo Town, Jingning, Gansu. On the 22nd, the Second Red Army was in Jingning Jiangtai Fort, and on the 23rd, the Sixth Red Army was in Xinglong Town and successfully joined the Red Army. So far, the Second Red Army ended the Long March, and there were more than 10,000 soldiers in the whole army. The Long March of the Second Red Army lasted nearly a year. After hard combat on the way, it broke through the siege and interception of the Kuomintang army, overcame the danger of snow-capped mountains and grasslands, and defeated the crisis of division within the party. Finally, the meeting of the three main forces of the Red Army was realized. After the Second Red Army arrived in northern Shaanxi, some personnel took a group photo. The second row, the second from the right, is Ren Bishi, and the third from the right is where the first, second, and fourth fronts of the He Long Red Army met - the strategic significance of the Long March of the Red Army in Huining, Gansu. The Long March is a declaration, the Long March is a propaganda team, and the Long March is a seeding machine. This is Mao Zedong's most representative exposition of the significance of the Long March. The Red Army met many times during the Long March, the main ones being: in October 1934, the Second and Sixth Corps of the Red Army met in Muhuang; in June 1935, the First and Fourth Front Corps of the Red Army met in Maogong; in September 1935, the 25th Army of the Red Army met with the Yongping Town of the Red Army in northern Shaanxi, and was jointly organized into the 15th Army of the Red Army; in October 1935, the First Front Army of the Red Army and the 15th Army met in northern Shaanxi, and the 15th Army was incorporated into the Red First Front Army; in July 1936, the Second and Fourth Front Corps of the Red Army met in Ganzi; in October 1936, the First, Second and Fourth Front Corps of the Red Army met in Huining and Jiangtai Fort. Every meeting of forces was accompanied by victory in battle. Without victory in battle along the way, there would be no meeting of forces. Therefore, the meeting of forces itself symbolized victory. During the Red Army's Long March, it experienced many heroic and bloody battles, such as the Battle of Yuanjiagou of the Red 25th Army, which killed more than 300 enemies, captured more than 1,400 enemies, surrendered more than 1,000 guns, etc., the Central Red Army's Four Crossing Chishui, rushing to cross the Dadu River, etc., including the Battle of Zunyi, which defeated and annihilated two enemy divisions and 8 regiments, capturing about 3,000 enemies; the Battle of the Red Fourth Front's Pocket, which annihilated 5,000 enemies, opened the door to Gannan, etc.; the Battle of Longjiazhai of the Second Red Army and the Sixth Red Army killed more than 1,000 enemies, captured more than 2,000 enemies, and surrendered more than 2,200 guns, etc. In these battles, the Red Army almost always won more with less, achieved amazing victories with heroic combat and flexible tactics, and then realized the meeting of forces. The Long March is the meeting of forces by the Red Army from various scattered base areas, walking, fighting, and doing mass work, for a common goal, converging in one direction like many tributaries flowing into rivers. Such a meeting of forces is the aggregation and concentration of strategic forces. The secret of strategy lies in concentration. With the concentration of strategic forces, there is the initiative to implement strategic operations. He Long and Ren Bishi were well aware of this truth. The Red Second and Red Sixth Corps they led met on October 24, 1934, and on the 25th they suggested to the Central Revolutionary Military Commission that "two corps should concentrate their actions." However, the Central Revolutionary Military Commission disagreed and said it was "absolutely wrong." On the 28th, He, Ren, and other leaders of the Second and Sixth Corps once again suggested "temporarily concentrated operations." Then in mid-November, they concentrated their efforts on the Longjiazhai Campaign, which played a major role in the development of the Xiangchuan-Guizhou base areas in Hubei, and also effectively cooperated with the Long March of the Central Red Army. After each meeting of the Red Army, the victory of strategic operations was immediately followed. For example, after the Red Front Army and the Red 15th Army met in northern Shaanxi, they immediately fought the Battle of Zhiluo Town under the unified command of the central government. The victory of the Battle of Zhiluo Town was a groundbreaking ceremony for "the task of the Party Central Committee to put the national revolutionary base camp in the northwest." Another example is that after the Red Front Army, the Red Front Army, and the Red Front Army met in the Shaanxi-Gansu-Ningxia Border Region, they fought the Battle of Mountain Castle under the unified command of the Central Military Commission. The victory of the Battle of Mountain Castle not only greatly enhanced the prestige of our army, but also played a positive role in dividing the enemy's barracks and promoting the realization of the policy of forcing Chiang to resist Japan. After the main force of the Red Army joined forces, it was able to concentrate its forces to fight some larger wars of annihilation under the unified command. Master the initiative of strategy. The Long March took place under the historical conditions of extremely sharp domestic class contradictions and ethnic contradictions between China and Japan. When the Central Red Army failed to oppose the enemy's fifth "encirclement and suppression", it also intertwined the struggle of the wrong line and the correct line within the party. Under such circumstances, the Party Central Committee represented by Mao Zedong, proceeding from the great justice of the state and the nation, resolutely put forward the policy of going north to resist Japan. The proposal of this policy elevates the Central Red Army's passive action of strategic retreat after the failure of the fifth anti-" encirclement and suppression "into a positive and enterprising political action that is righteous and awe-inspiring to the people of the whole country and the whole army. As Edgar Snow wrote in "A Journey to the West": "This helped them turn what might have been a discouraged retreat into a spirited and victorious march." The policy of going north to resist the Japanese, which upheld the justice and necessity of the Long March, became famous and greatly stimulated morale. The Japanese invaders were the enemy of the whole nation, and the Red Army went north to resist the Japanese and won the support of the whole nation. The "suppression" of the Red Army by the reactionary army put itself in opposition to the resistance to the Japanese and was opposed by the whole nation. Adhering to the policy of going north to resist Japan also effectively united the whole party. In the party's disagreement between "going north" and "going south", the Party Central Committee and Mao Zedong firmly insisted on going north to resist Japan, and thus united the whole party and the whole army. It was reasonable to go north to resist Japan, but unreasonable to go south and west to escape. This prompted the three main forces of the Red Army to finally meet in the northwest, avoiding the danger of Zhang Guotao's division. Mao Zedong said: "As soon as the Long March is over, a new situation will begin." The meeting marked the end of the Red Army's strategic retreat and the completion of the strategic transfer, ushered in the strategic stage of the new situation in the Shaanxi-Gansu-Ningxia Soviet Area, and prepared for the implementation of the strategic change to the national revolutionary war. This is a historic change. The successful meeting of the main forces of the Red Army in the northwest became a turning point in the strategic change. In December 1935, the Political Bureau of the Central Committee held a meeting of Wayaobao and decided on the strategy of establishing an anti-Japanese national united front. Explain that after the Red Army's Long March was joined, the Party Central Committee and Mao Zedong could plan and decide on political strategy issues within the "base camp" in a relatively stable (compared to the combat environment that was chased and blocked during the Long March), and they could introduce new strategies. If the victory of the Long March is a victory of the strategy of going north to resist Japan, then the Long March is only the first step in implementing the strategy of going north to resist Japan. In the northwest, the Long March is over, but the anti-Japanese struggle is not over. The whole nation's anti-Japanese struggle must continue unremittingly. And all this can only be implemented after the Red Army meets. Facts show that after the Red Army joined forces and held high the banner of anti-Japanese and national salvation, it had a great impact on Zhang Xueliang's Northeast Army and Yang Hucheng's Northwest Army, so much so that the "Xi'an Incident" occurred, which contributed to the establishment of a broad national revolutionary united front. The Red Army completed the first great Long March in human history. Facing a powerful and murderous enemy, the Red Army faced a dangerous and difficult environment. It took more than a year and traveled 25,000 miles to complete the Long March, mainly relying on the revolutionary spirit. The Long March spirit contains many contents, but there are two main points: it is the spirit of forcibly crossing the Dadu River, storming Lazikou, fighting heroically, fighting one after another, and not afraid of sacrifice; it is the spirit of climbing snow-capped mountains, crossing grasslands, enduring hardships and enduring hard work. In difficult environments, the will is firm, and the revolutionary ideal is higher than the sky. The revolutionary character of the Red Army was most evident, concentrated and profound during the Long March, and became the most precious wealth of our Party and our army. The Red Army completed the tasks of the Long March with this spirit, and the victory of the meeting of troops made this spirit even more brilliant. This spirit can cultivate people's noble sentiments, enhance the combat effectiveness of the troops, and complete all difficult and difficult tasks. This spirit will have a profound impact on the construction of civilization and work style in our country and our army.
