Huaihai Campaign
He was the major commander during the Huaihai Campaign (November 1948 to January 1949). It was at his suggestion on January 22, 1948 that the two armies of Liu and Su followed a sudden-concentrate, sudden-disperse strategy that led to this decisive victory in late 1948, with the destruction of five Nationalist armies and the killing or capture of 550,000 Nationalist soldiers. Su's army alone destroyed 4 nationalist armies, and was the decisive force in destroying the fifth.
