Before Zhang Xueliang and Yang Hucheng launched the "military advice", Dai Kasa had already learned in advance, so why didn't he dissuade Chiang Kai-shek?
On December 12, 1936, the "Xi'an Incident" that shocked China and foreign countries broke out, and Zhang Xueliang, commander of the Northeast Army, and Yang Hucheng, commander of the Northwest Army, together detained Chiang Kai-shek by force, in order to pressure Chiang Kai-shek to abandon the suppression of the Communists and unite to resist Japan and save the country.

At first, the Kuomintang headquarters in Nanjing knew nothing about this, until at three o'clock in the afternoon of the same day, Chen Anbao, commander of the Kuomintang 79th Division stationed at Tongguan, sent an urgent telegram: There was a mutiny in Xi'an, and the chairman of the committee was unclear. The first to get the news was not Dai Kasa, a secret agent of the military command, but He Yingqin, but He Yingqin immediately blocked the news, and he had his own small calculation.
After a while, Song Meiling also got the news from Kong Xiangxi, and the Kuomintang suddenly became a pot of porridge, and only Dai Kasa was still in the dark. When Soong Mei Ling found a way for Dai Tou to deal with it, Dai Kasa learned that Chiang Kai-shek had been detained, and Dai Kasa was suddenly sad, and there was self-blame more remorse, in fact, he had already obtained a secret telegram before Chiang Kai-shek went to Xi'an, claiming that Zhang Xueliang and Yang Hucheng were ready to force Chiang Kai-shek to resist Japan by means of "military advice". But why didn't Dai Kasa dissuade Chiang Kai-shek from going to Xi'an?
Zhang Xueliang and foreign friends
In October 1935, after a 25,000-mile long march, the Red Army came to northern Shaanxi with difficulty, the Red Army suffered heavy casualties at this time, and there were not many troops left, and Chiang Kai-shek wanted to take this opportunity to completely eliminate the Red Army in one fell swoop. To this end, Chiang Kai-shek urgently transferred more than 100,000 northeast troops from Hubei to the northwest, and also arranged for Yang Hucheng's northwest army and Hu Zongnan's central army, with a total strength of more than 300,000 troops, and appointed Zhang Xueliang as deputy commander-in-chief of the "Northwest Suppression of the Communists." Chiang Kai-shek was full of confidence in this arrangement. At this time, Dai Kasa also arranged a large number of secret agents and secret radio stations in the west to cooperate with Chiang Kai-shek's task of "suppressing the Communists."
Dai Kasa was worried that Zhang Xueliang and Yang Hucheng would unite to oppose Chiang Kai-shek's orders, so he worked Zhang Xueliang and Yang Hucheng's main generals, deliberately creating contradictions between the generals of the two sides in order to break Zhang Yang's alliance. However, Dai Kasa still underestimated Zhang Xueliang and Yang Hucheng, both of whom were very politically minded generals, and they saw Dai Kasa's little trick, the relationship between the Northeast Army and the Northwest Army was one of unity and survival, and separation was death. Therefore, Zhang Xueliang and Yang Hucheng adopted the method of making a plan, not going up and down, and secretly communicating with the light, and secretly crossing the sea to deceive Dai Kasa's agents, and also deceived the agents of the Central Unification.
Chiang Kai-shek and key members of the Kuomintang
By the beginning of December 1936, Chiang Kai-shek was traveling frequently to Lanzhou, Luoyang, Xi'an, and Jinan, and he and the main generals held meetings to discuss the encirclement and suppression of the Red Army in northern Shaanxi, and at the same time Chiang Kai-shek was preparing to go to Xi'an with the Kuomintang members and put pressure on Zhang Xueliang and Yang Hucheng again, demanding that they immediately attack the Red Army in northern Shaanxi without delay.
However, at this time, Dai Kasa obtained a very important piece of intelligence: "The governor of the northwest region, Jiang Xiongfeng, is secretly in contact with a senior leader of the Red Army in northern Shaanxi." Dai Kasa was greatly shocked, and he immediately rushed to Luoyang to submit this information to Chiang Kai-shek, and Chiang Kai-shek also agreed with Dai Kasa's view that if this information was true, then the consequences would be quite serious. Chiang Kai-shek immediately gave instructions to Dai Kasa that the truth of the matter must be ascertained, and after receiving the order, Dai Kasa rushed back to Nanjing and asked Jiang Xiongfeng, the head of the northwest region of the secret service, to thoroughly investigate the matter.

Jiang Xiongfeng did not dare to be sloppy, and he received accurate news from Zhang Xueliang's cronies: "Zhang Xueliang and Yang Hucheng are preparing to launch a military advisory in the near future to force the chairman of the committee to stop suppressing the Communists and unite with the Communists to resist Japan." After receiving the exact information, Dai Kasa immediately rushed to Chiang Kai-shek's side personally, and at this time Chiang Kai-shek was about to fly to Xi'an, and Dai Kasa hurriedly told Chiang Kai-shek about Zhang Xueliang and Yang Hucheng, but at this time Chiang Kai-shek made a strange judgment.
Chiang Kai-shek thought that Zhang Xueliang had a very good relationship with himself, and he believed that Zhang Xueliang was a man of morality, had a heart of admiration for himself, and would not betray himself. As for Yang Hucheng, previous intelligence showed that the relationship between Zhang Xueliang and Yang Hucheng was tense, and without Zhang Xueliang's cooperation, Yang Hucheng could not be consulted. In this way, Chiang Kai-shek ignored Dai's intelligence and insisted on personally flying to Xi'an to supervise the battle, which led to the later "Xi'an Incident."
Yang Hucheng and Zhang Xueliang
Therefore, when Dai Kasa learned that Chiang Kai-shek had been detained by Zhang Xueliang and Yang Hucheng, his heart was both sad and remorseful, his personal honor and disgrace were completely bound to Chiang Kai-shek, and he regretted that he had not been able to dissuade Chiang Kai-shek from going to Xi'an. However, later, he personally flew to Nanjing, and Chiang Kai-shek scolded him with his mouth, but in fact, his heart was still touched by Dai Kasa's loyalty, and after the "Xi'an Incident", Dai Kasa was not only not snubbed, but was even more heavily valued by Chiang Kai-shek, and Dai Kasa was also considered a blessing in disguise.
