In 1944, the Flying Tigers of the US Air Force came to China to participate in the war in aid of China's anti-Japanese war, and the Japanese army suffered heavy losses. To this end, the Japanese army in South China launched the Henan-Xiang-Guangxi Campaign aimed at opening up the mainland transportation line, one of the attempts was to destroy the Southwest China Air Force Base. The 23rd Army of the Japanese Army stationed in South China secretly formed a special attack team and planned to launch a devastating attack on Guilin Yangtang Airport. On the night of the special attack team's attack, it was ambushed by the Kuomintang garrison at the airport, and the special attack team was almost wiped out. Such a top-secret operation was actually known to the Kuomintang garrison at the airport in advance. The commander of the Japanese special attack team, Kumamoto, who was lucky enough to withdraw, realized that one of the six Chinese hired with a large sum of money was a Kuomintang spy; when Kumamoto tried to find out who was the spy among the three surviving Chinese, Colonel Mike, the commander of the US military at Yangtang Airport, also suspected that there was a problem inside, otherwise how could someone expose the target before the ambush began. When Kumamoto hid in Nishimura and waited for the action instructions of the headquarters liaison officer, the fear of death enveloped the three surviving Chinese, and suspicion and speculation also spread among the three Chinese. After the KMT garrison at the airport finished their quick search, Kumamoto captured a KMT officer from outside. The Chinese, codenamed "Mango", was unaware of the trick and fell into Kumamoto's hands when he was trying to rescue him alone. Just as Kumamoto was furious and ready to deal with "Mango", a burst of bullets came from the darkness, and Kumamoto was shot and injured, and the other two Chinese died on the spot.
