１９２９年南京国民政府召开军事编遣会议以后，蔡廷锴部改编为第六十师，蒋光鼐部改编为第六十一师。１９３０年中原大战期间，蒋、蔡二部扩展成为第十九路军，蒋光鼐为总指挥，蔡廷锴为军长。该部在中原大战中为蒋介石立下汗马功劳。战后，被调到江西参加对红军的“围剿”。 After the military establishment meeting held by the Nanjing National Government in 1929, Cai Tingyi was reorganized into the sixtieth division and the department of Jiang Guanglu was reorganized into the sixty-first division. During the Central Plains War in 1930, Chiang Kai-shek and the Second Division expanded to become the 19th Route Army, with Jiang Guangtao as commander in chief and Cai Tingtao as commander. The Central Military Commission for Chiang Kai-shek in the Central Plains war made a contribution. After the war, he was transferred to Jiangxi to participate in the “encirclement and suppression campaign” against the Red Army.
