The arrival of the reinforcements greatly boosted the morale of the defenders and the advance guard of the 21st Regiment of the 7th Brigade of the communist Western Manchurian 3rd Division launched a counterassault on the nationalists with the help of other communist units, and successfully took back the positions at railway junction previously lost on the same afternoon, while inflicting heavy casualties on the nationalists in the process, and the heavy casualties stopped the offensive of the nationalist 30th Division completely. After the struggle for Siping had begun, both Chiang Kai-shek and Mao Zedong in their distant headquarters were concerned about the development and both frequently inquired the progress on the battlefield. Chiang was determined to take Changchun and thus Siping must be taken first to open the path for Changchun, while Mao felt that Siping must be held at all cost and on April 22, Mao telegraphed Lin Biao to order him to hold on and wait for the campaign to turn for the better. From April 18, through April 26, 3 divisions from the nationalist New 1st Army and the 71st Army took turns to assault the enemy positions, but were all beaten back by the enemy in favorable terrain. By the evening of April 26, 1946, heavy casualties forced the offensive of the nationalist 71st Army to a complete stop, while that of the nationalist New 1st Army was reduced to skirmishes.
