Tengchong City is the strongest city in western Yunnan, and the Tengchong city wall is full of boulders, high and thick. The fortresses on the city wall are lined up, and the four corners of the city wall are more heavily fortified side guards. Tengchong City has both Laifeng Mountain as a barrier, and its commanding heights can contain the entire front of Tengcheng, and the two places rely on each other when defending. Moreover, after more than half a year of operation, the Japanese fortifications not only built strong permanent fortifications and fortress groups in the two places, but also prepared sufficient food and ammunition, and the grass mustard wing of the 56th Division of the Japanese army was ordered to defend Tengchong to the death.

Take Tengchong, flank and detour, and concentrate forces to capture Songshan, then the road to Longling will be unblocked, and the situation of Thunder attacking Burma will be opened, but how can this situation be easily opened? Zhao Zhi understood that if he wanted to attack Tengchong City, he must first capture Laifeng Mountain, and only by capturing Laifeng Mountain could he finally encircle and annihilate Tengcheng to defend the enemy, but before attacking Laifeng Mountain, Lei Ting must take Zhai Gongfang. The Zhai Gongfang will be the first pass encountered by the troops crossing the river, especially the terrain of the Zhaigong House is suitable for defense, and the Japanese army will never leave it undefended.

The Japanese officers and men had been deployed on the Nu River for more than half a year, and they were already completely familiar with the local terrain and climate, and the Japanese army's fortifications were extremely cleverly arranged in the mountains and jungles. Bunker-like strongholds, rat-hole skirmishers, bird's nest-type tree firepower points, and cave-type shelters can be described as dotted around, supporting each other and echoing each other, and there are many secret passages between strongholds and strongholds, and between hills and mountains. Looking at the ethereal mountain peaks in the clouds and mist in the distance, Zhao Zhi knew that as long as the troops could break through the Zhai Mansion and be able to rush to Tengchong.

"It's time to wake them up" The scout who went out to explore the road had already sent back the information that the Japanese army had not found the thunder crossing of the river, and a playful smile appeared on the corner of Zhao Zhi's mouth, who had been waiting for a long time. The Thunder side began to speak from a company of Jewish soldiers who had crept forward to the front, and the officers who led the team gave the order, and the soldiers lying in the trench shouted loudly. The sudden shouts of landslides and cracks in the fog made the Japanese troops panic, and they opened fire with light and heavy weapons, and the Japanese troops on the right flank even ignited the oil that had been splashed in front of the position in advance in order to disperse the fog.

The firing points of the bunkers in the forward area of the Japanese army opened fire one after another, and for a time the sound of guns and artillery was mixed, and in the clouds and mist of Gaoligong Mountain that did not disperse for eternity, the position where guns and bullets were flying was like making a big disturbance in the heavenly palace. For a while, the sound of gunfire and artillery actually suppressed the shouting and killing of even the Jewish soldiers, and after about ten minutes, the Japanese finally realized that something was wrong, because the shouting and killing of the other party was always floating in the clouds, but they did not even see a single figure of the other party on the battlefield.

The sudden burst of gunfire, ballistics and burning soil in the fog provided the best guidance for the thunderous artillerymen, the artillery officer waved his flag, the 75 mm and 105 mm guns that had already been assembled opened fire in unison, and the silent mountains were awakened by the dense artillery fire, especially in the valley, echoing and trembling, and one cannon could fire several shots.

When the dull sound of artillery accompanied by the sharp whistling of shells sounded, the Japanese troops hiding in covered bunkers, burrows, and half-excavated bunkers realized that they were facing a great crisis. Boom, boom, boom, when the first round of shelling shook the ground, the Japanese defenders hiding in the fortifications were as anxious as rats thrown into iron barrels waiting to be filled with water, and those who were unlucky were directly annihilated by the ashes like the fortifications, or were so shocked that their noses and mouths were bleeding and dying. The Japanese soldiers who were lucky enough to escape the first round of shelling were also lying dead in the bunker, in such a large-scale artillery battle, running around will only make them die faster, and the only way is to stay in the bunker and pray for their good luck to escape the shelling.

After being awakened by artillery fire, Hideki Sato, a Japanese guard stationed in Sai's office, immediately jumped out of bed barefoot to call the forward garrison commander, who reported to him that due to the fog, nothing could be seen from the top of the mountain. The artillery bombardment of the opposing Chinese army was very heavy, and there was also heavy artillery mixed in, and the defenders' positions were demoralized, with heavy casualties, and they needed support. The Japanese army guarded the Sai Gongfang with only one brigade, which would make Sato Hideki where to find reinforcements, he could only tell the front line to pay attention to the movement in front at any time, once the artillery fire of the Shina army extended, immediately deploy a counterattack, and absolutely not let the Shina people occupy the position.

"Kill, rush up, rush up and occupy the position" As soon as the artillery fire stopped, there was a tidal shout from the bottom of the hillside, which was the Chinese army taking advantage of the artillery attack on the position to attack and charge. The sober officers drove the soldiers out of the collapsing bunkers and tunnels, pulled out hot machine guns from the scorched earth and began to return fire, this time the remaining Japanese troops on the position even used mortars, and they did not allow the Chinese army to set foot on their positions, even if they were all killed.

The "group of fools" received the coordinates sent back by the forward scouts with walkie-talkies, the hand flag of the artillery officer on duty fell again, and the artillery group that had just fired a round again let out an angry roar, and the shells of 75 caliber and 105 caliber came out of their disembowels and went straight to the Japanese troops in the middle of the mountain. Boom, boom, boom, all the shells accurately landed on the Japanese position at the pass, with the violent explosion on the position, the stumps of the Japanese soldiers flew in the air in the pillar of smoke, and the Japanese garrison commander Takahashi who defended the right wing pass was eager to strangle the cunning people on the opposite side with his hands at this moment.

"Artillery Extended Strike" The artillery officer began to roar loudly accompanied by the gesture of artillery fire extension, and no matter how strong the field fortifications were, they could not withstand the bombardment of large-caliber howitzers. Especially Zhao Zhi was determined to deter the enemy at this time, and after two rounds of artillery bombardment, the Thunder artillery group began to shrink its firepower, taking this opportunity for the Japanese to take the opportunity to reinforce the forward position. When the Japanese reinforcements arrived at the gently sloping position under the windward ridge line in front of the pass, they were stunned by the scene in front of them, the original vertical and horizontal trenches, fire support points, and excavation bunkers were all moved to flat ground, and the ground was full of green smoke and loose soil by artillery fire, and those miserable white and bare tree roots seemed to be still recalling the horror just now.

Looking at the flashes in the middle of the mountain, a bald mercenary pinched his waist and shouted: "Little devil, you also have today?" Before, Lao Tzu let you turtle bastards blow up miserably, even in the sky and on the ground, almost blew up so much that Lao Tzu's surname forgot anything! What's going on now? Let's get blown up! Let's be honest! Blow up your sons of bitches" Although the bald mercenary's words were vulgar, he expressed his personal feelings, and he didn't have to think about it to know that this bald mercenary must have been a national army before joining the thunder.

After the artillery fire was extended, the panicked Japanese follow-up troops were driven into the fortifications by the officers from the tunnel behind the mountain, but the news that the tunnel had collapsed soon came from the front, and the Japanese had no choice but to use small units to disperse and infiltrate the reinforcement area, in order to reduce casualties. At this moment, the Japanese garrison troops defending the left and right flanks of the pass can be described as miserable, the altitude of the pass of Zhaigongfang is nearly 4,000 meters, and the terrain is dangerous, but the steep terrain also limits the Japanese army from transporting a large number of materials to build permanent fortifications, and the Japanese army can only take materials on the spot.

Just as the Japanese follow-up reinforcements were rushing to repair the fortifications and bunkers, the artillery group simultaneously carried out covering fire on the left and right flank positions of Yakou. After this attack, no matter what posture the Thunder soldiers made, the Japanese troops ignored it, and all of them cowered in the mountain tunnel behind the ridge line and refused to come out. The two cluster artillery bombardments of the thunder caused more than half of the Japanese brigade stationed in the position of Zhaigongfang to suffer casualties, and once the other side began to attack the broken forward position, the Japanese army did not know whether they could hold it.

Zhao Zhi's brows were tightly locked, the sky had already dawned, and the fog on the Nu River had long since dispersed, but the fog here in the Zhai Mansion still did not disperse, although the fog protected the soldiers, but to some extent it also affected the accuracy of the shelling. "The terrain of the house is dangerous, and the Japanese army has arranged for a large group of troops to guard it, and the clouds and fog hinder the effect of our artillery bombardment. The two rounds of artillery fire just now only destroyed the surface positions of the Japanese army, and the fortress bunkers buried by the Japanese army in the ground are estimated to be quite complete, and our army has paid heavy casualties if it rashly attacks and commands" Seeing what Zhao Zhi was thinking, Xiao Ziyun, as an operational staff officer, reminded him in a timely manner.

Zhao Zhi nodded in agreement with Xiao Ziyun's words, "Suspend the shelling, call the soldiers in front to standby, and transfer the sweeping team, it's time for them to show up" When Zhao Zhi formed the Jewish Legion in Yangon, he had recruited thousands of Chinese from China. Among them, 2,000 people became Thunder's reserve mercenaries, and the rest were thrown into the training camp by Yu Dazhi, and the specially invited Burmese taught them the means of survival in the mountains and forests, and saw several rounds of screening and elimination, and finally the remaining 1,200 people were divided into four companies, Zhao Zhi called them the sweeping team, which was specially used to deal with the Japanese sweeping team in mountain warfare.

The Japanese army is a good hand at digging holes, and in more than half a year, they dug a lot of tunnels on the Zhai Gongfang position, and there are alternate exits from the Japanese tunnels everywhere under tree holes, in the cracks of rocks, under gentle slopes, and in bushes. But now it is the sweeping team that rushes up to the middle of the mountain, they are like blocking a mouse hole, and wherever the Japanese soldiers appear, they rush to wherever they are. First the submachine gun fired, then greeted with grenades, for the mouth of the large tunnel, after suppressing its firepower, directly with the flamethrower pressed up for a fierce spray, less than half an hour, the Japanese army worked hard to make out of the Zhai Gongfang position The tunnels were mostly sealed by the cleaning team.

"It's too easy, if that's the case, we'll do it too" watched the sweeping team's overwhelming attack and the speed of its march, and the Jewish soldiers muttered to themselves as they lay in the trenches waiting for the order to attack. Especially those Jewish soldiers who were fortunate enough to follow Zhao Zhi to fight with the Japanese army in Jinzhong, they were even more suspicious, could it be that the Japanese army sent all the elite troops to Shanxi, and the Japanese troops stationed here were second-rate troops, otherwise how could they be easily taken by the sweeping team to take most of the positions.
