Peng's forces were the most poorly armed of the newly re-organized army but were responsible for the area around the communist capital, Yan'an. In March 1947, Kuomintang General Hu Zongnan, invaded the area with 260,000 soldiers. Hu's forces were among the best-trained and most well-supplied Nationalist units, but one of Zhou Enlai's spies was able to provide Peng with information about Hu's strategic plans, his forces' troop distributions, strength, and positions, and details about the air cover available to Hu. Peng was forced to abandon Yan'an in late March but resisted Hu's forces long enough for Mao and other senior party leaders to evacuate safely. Mao wanted Peng to provoke a decisive confrontation with Hu immediately, but Peng dissuaded him. By April, Mao agreed that Peng's objective was to "keep the enemy on the run... tire him out completely, reduce his food supplies, and then look for an opportunity to destroy him."
