In March 1933, during the Great Wall War, the 37th Division of the 29th Army reinforced Xifengkou to prevent the Japanese army from further invading North China. The Japanese, with their well-equipped equipment, quickly seized the outlying positions under the cover of aircraft artillery. The Chinese army used night raids to restore positions, and the two sides came and went, and the positions changed hands several times.
Seeing that this was not the way to go, the 29th Army decided to change from passive to active, raiding the Japanese army in the night and catching the enemy by surprise. The 37th Division divided into two routes, bypassing the Japanese troops in front, directly into the rear of the enemy, and in one fell swoop, the Japanese cavalry brigade and artillery brigade were eliminated, and ambushed the front-line Japanese troops who rushed to reinforcement, which temporarily alarmed the Japanese army.
The Japanese army was extremely afraid of the 29th Army's large knife, and in order to protect itself, the Japanese army rushed to make thousands of iron neck guards overnight, wearing them on their necks, wearing them when they ate, wearing them when they went to the toilet, and even when they slept.
The cavalry brigade and the artillery brigade were cut off by the 29th Army while sleeping, and this humiliating incident was so far-reaching and deeply rooted in the hearts of the people that even the base camp knew about it. The base camp exchanged the advanced experience of the iron neck to all the Japanese troops in North China. All Japanese troops must not leave the iron neck guard, the iron neck is their amulet, and the iron neck is more dear to them than the mother.
However, later combat proved that such protection was useless, and the 29th Army did not cut their necks anymore, but instead split their heads. The officers and men were all big men, one head taller than the Japanese, and they picked up large knives and split them from top to bottom, and they could split the Japanese in half at once.
Some locals once recalled that the 29th Army was all good players, he stood on the mountain, personally saw the two sides fighting, three devils with bayonets besieged a big Chinese warrior, this Chinese warrior held a large knife, a block, and then turned around, the devil's bayonet was stabbed empty, the Chinese warrior twisted his waist, a slash of the arm, - a devil's head rolled down, rolled down the hillside bone and rolled out a long way. Another devil's bayonet stabbed, and as soon as the Chinese warrior was short, the big knife ran to the devil's legs and cut off one of the legs.
That is, in the blink of an eye, the two devils were reimbursed, and the third devil was scared out of his guts, turned around and ran, but the devils had short legs and could not run fast, and the big Chinese soldiers had long legs, and took a few steps to catch up, splitting the devils from the right shoulder to the crotch, and split it in half.
In the fierce battle at Xifengkou, the Japanese army, which had an absolute superiority in weapons, hardly took advantage of any advantage, and had to withdraw from Xifengkou and attack Luo Wenyu instead.
