After the end of the War of Resistance Against Japanese Aggression in 1945, the Jinji-Hebei Luyu Military Region successively set up 6 columns, namely 1 column, 2 column, 3 column, 4 column, 6 column, and 7 column, and the commanders were Yang Dezhi, Chen Zaidao, Chen Xilian, Chen Geng, Wang Hongkun, and Yang Yong.
Under Liu Deng, Yang Dezhi's name was rarely mentioned, and the record of the 7 columns was little known.
In fact, the 6 columns established in 1945 were slightly adjusted with the columns commanded by Liu Deng.
In September 1945, the Jinji-Hebei Luyu Military Region established the 1st Column, 2nd Column, 3rd Column and 4th Column, while the 6th Column and the 7th Column were established in November.
After Participating in the Battle of Handan, Yang Dezhi was sent to the northeast to fight according to the strategic needs of the Central Military Commission. It was only when the situation changed in eastern Hebei that it did not arrive, and remained in the Jin-Cha-Ji Military Region.
After staying in Jin-Cha-Ji, 1 Column did not return to the establishment, but stayed in the Jin-Cha-Ji Military Region, and stayed in this for 1 year. That is to say, Yang Dezhi's tenure under Liu Deng was extremely short, only a few months.
In December 1946, 1 column returned to the command of Liu Deng, due to the lack of cadres in Jin-Cha-Ji, Yang Dezhi and deputy commander Zeng Siyu, as well as the chief of staff stayed behind, and Su Zhenhua led the team south.
In May 1947, according to the instructions of the superiors, the 1st column and the 7th column were merged to form a new 1st column.
Both the 7th Column and the 1st Column were from the Jiluyu Military Region, and Yang Yong was familiar with these two units.
In the middle of the War of Resistance Against Japanese Aggression, Yang Dezhi led his troops to open up the Hebei-Luyu Military Region, and as commander, Yang Yong led the troops to open up the Luxi Anti-Japanese Base Area and developed into the Luxi Military Region. In order to meet the needs of development, the two military regions were merged into the new Jiluyu Military Region, with Yang Dezhi as commander and Yang Yong as deputy commander.
Until 1944, Yang Dezhi was transferred to Yan'an, and Yang Yong was the commander of the military region and the commander of the Seventh Column until 1945.
1 column lacks column commanders, and 7 columns need to strengthen military and political work. The combination of the two forces will not only strengthen the military force, but also strengthen military command and political work.
Under such circumstances, the two columns were merged into the new 1st Column, with 4 brigades under its jurisdiction and a strength of about 25,000 troops.
In the later Battle of Southwest Lu and the Battle of Advancing into Dabie Mountain, the 1st Column played a very important role. Especially in the battle against Yuncheng, a column annihilated 15,000 enemies, and was commended by Liu Deng's chief by telegram and recorded a great merit.
In 1949, after the Battle of crossing the river, Yang Yong led three armies to liberate Guizhou and made great contributions to the liberation of the great southwest.
