Zhang Zuolin's death in Huanggutun was not his negligence. On the contrary, as a local lord in the northeast, he is also highly confidential about his travels, and each trip is strictly planned and heavily guarded along the way to ensure that nothing goes wrong. And in Huanggutun was blown up and killed because of his own improper use of people, so that there were internal ghosts around him.
On June 1, 1928, Zhang Zuolin originally traveled on this day, but considering the recent tension in relations with Japan, Zhang Zuolin originally decided not to move on this day, taking into account the recent tension in relations with Japan. For them, the longer the time drags on, it is not only not conducive to the implementation of the plan, but also not conducive to personal safety. On the morning of June 2, several of Zhang Zuolin's wives had already boarded the train, and the relevant servants had also packed up their business and got on the train, and they were about to leave, but Zhang Zuolin did not appear for a long time.
At 1 o'clock in the morning of June 3, Zhang Zuolin finally moved, he thought he was well considered, at this time the departure was absolutely confidential, who knew that the inner ghost was walking with him, at this time Zhang Zuolin's whereabouts were completely exposed, and the inner ghost leaked his route planning and time to the Japanese base camp.
Zhang Zuolin's special train has a total of 20 cars, and as a marshal, he chose to be in the middle of the special train, that is, car 10. Among those who accompanied him were Prime Minister Pan Fu, Mo Dehui, the patriarch of the Northeast region, and Yu Guohan, chief of the General Staff. What's more, there are two Japanese advisers among the personnel at any time, they are Makoto Izuya and Takema Machino, and in the case of Zhang Zuolin and Japan's confrontation, there are these two people around, which can be said to be a time bomb that will be detonated at any time.
At about 6:00 a.m. on June 3, Zhang Zuolin's special train arrived at Tianjin Station, where Takema Machino quietly disembarked. At 4:00 p.m., the special train arrived at Shanhaiguan, during this time, the inner ghost had plenty of time to contact the base camp, and this section of the road, arranged personnel to assure him, has ensured that there is no mistake, there are heavy troops along the way, and at this time to the end is not far, so Zhang Zuolin completely relaxed his vigilance, after finishing the meal and playing cards with the entourage.
Seeing that they were about to reach Fengtian, everyone let their guard down, but the Japanese planted 120 kilograms of explosives in a place called Sanqiaodong not far from Fengtian. At 5:23 a.m. on June 4, when Zhang Zuolin's 10th carriage just reached the Three Bridges Cave, the Japanese carried out a very accurate blast, Zhang Zuolin's carriage was blown to pieces, regarding the operation against Zhang Zuolin, the Japanese considered him more carefully than him, the Two Japanese staff officers had monitored him in advance, and at the place of the Three Bridges Cave, they made hands and feet on the rails, and arranged for a special force to ambush near the Three Bridges Cave in order to repair Zhang Zuolin's knife in the case of a blasting mistake.
Kawamoto Daisaku, who arranged this operation, was very proud, and in Zhang Zuolin's incident, it was because Takema Machino got off the car early, and he was overconfident that he did not notice it, so that he fell on the last journey.
