In fact, Zhang Chi would rather the Japanese army fight like this.

If you fight like this, although the engineer regiment will not be able to rest because of the harassment of the Japanese army, it is better than being rushed up by the Japanese army when it runs out of ammunition and food. And 200 will arrive at dawn, then it is better for the Japanese devils to drag the time down like this.

Of course, Zhang Chi also knows that things will never be so simple...... The reason why the Japanese army dared to fight so unhurriedly was probably because they knew that the 200th Division was blocked and did not arrive so quickly, and even the Japanese army knew that there were no Chinese reinforcements rushing to Tangji from other directions, so they dared to implement the strategy of exhausting troops in such a calm manner.

Zhang Chi also felt helpless about this, and the Japanese army was much more meticulous in intelligence work than the expeditionary force.

Of course, there are objective reasons for this, such as the Japanese army's deception and deception to take advantage of the Burmese people's hatred of the British army and their desire for independence, so that the Japanese army can easily get information from the Burmese people.

But in fact, there are also subjective reasons, such as the Japanese army also sent a large number of plainclothes to collect intelligence in various parts of Myanmar before the war, and for example, the Japanese army also knew to use the beliefs of the Burmese people to make a Bomojo to fool the Burmese people, which shows that the Japanese army attaches great importance to intelligence work and does it very carefully.

On the contrary, although the Chinese army also has good resources, such as the consent and assistance of the British army, although this is a superficial agreement, although the British army is even dragging its feet behind the scenes, but if the Chinese side has the foresight to send plainclothes into Burma to collect intelligence like the Japanese army before the war, this can also be done...... How could it be that the expeditionary force was blinded after entering Burma, and the maps they took were still maps drawn for decades, and they couldn't find a place. It is not even known how many divisions of the Japanese army participated in the battle, and where they were located.

These problems are actually very easy to solve, and it is only necessary to send a few plainclothes and a few radio stations to mix in with the overseas Chinese, keep in touch with the expeditionary force in various important places, and report the Japanese offensive dynamics at any time, but the Chinese army did not do this.

Perhaps because the Chinese army had always thought that the British would provide them with this information, or perhaps they had assumed that the Chinese army was here to help the Burmese drive out the Japanese invaders, the Burmese people would also provide this information to the expeditionary force...... But there is no such thing as a war, and the fact is that neither the British army nor the Burmese people have provided any valuable information, and not only have they not provided a lot of false information with ulterior motives to interfere with the strategic judgment of the top management of the expeditionary force.

As the saying goes, "knowing oneself and knowing one's opponent will not be defeated in a hundred battles", this sentence refers to the importance of intelligence. This is because only when we have a clear understanding of our own situation and that of the enemy can we formulate a corresponding and reasonable battle plan with a definite purpose.

Otherwise, there will be an unrealizable battle of Tonggu with a pat on the head, as the top brass of the expeditionary force did, and after the battle of Tonggu, there will be an unrealizable battle of Pingmanna, and after the battle of Pingmana, there will be an unrealizable battle of Mandalay...... None of these three battles could be fought, and all of them were forced to abandon for one reason or another.

From this point of view, the Chinese expeditionary force seemed doomed from the start.

Fortunately, Zhang Chi gave enough detailed information at the critical moment to find a little opportunity in Tangji to block the Japanese 56th Division.

It's just that Zhang Chi is not sure if this change will be the same as before...... I thought I could change history, but it always returned to the original track of history for one reason or another.

Zhang Chi is also very helpless about this point, as the so-called "planning is in people, and success is in heaven", he can only say that he is doing his part!

"Platoon commander!" At this time, Xiao Zhejiang, who was on guard, whispered to Zhang Chi a few meters away: "The devil has moved!" ”

Hearing this, Zhang Chi hurriedly turned over and put the gun on the trench, looked down through the sniper scope, and sure enough, he saw several tanks "rumbling" with a team of devils slowly approaching the 159 heights.

I was a little surprised to see this battle...... According to the habit of devils attacking, they will first fire for a few minutes and then launch a charge, why don't they come up at this time. And this time the number of people seems to be quite large, at least two squadrons of more than 300 people.

"Flares!" Zhang Chi shouted.

"Teng!" With a single sound, a flare rose into the sky and illuminated the murderous Japanese troops at the foot of the mountain.

The Japanese didn't even look up, and hid behind the tanks to prepare...... This made Zhang Chi feel that something was wrong, the Japanese army was more than 400 meters away from the defense line of the engineer regiment. Although the firepower of the engineer regiment could reach the Japanese army at this distance, they generally did not start fighting at this distance in terms of hit rate, and the Japanese army was also very aware of this, so they usually even rushed forward at a trot when they were so far away.

But now...... They crouched behind the tank and didn't move, as if they were waiting for something.

What are they waiting for?

Then Zhang Chi found something hanging from the waist of a Japanese soldier in the sniper scope...... After a closer look, Zhang Chi couldn't help but be startled, it was a gas mask!

Feeling the wind direction at this time, Zhang Chi shouted: "It's not good, the devil wants to hit the gas bomb!" ”

"Gas bombs?!" When the soldiers heard this, their faces changed drastically.

Zhang Chi did not guess wrong, Masao Watanabe was going to use poison gas bombs.

You must know that the 56th Division is a force that will be interspersed with Lashio, which can almost be said to determine the outcome of the entire Burma battlefield, and to carry out such a mission, it is conceivable that it is very likely to encounter hard nails on the road...... In order to be able to quickly pull out these hard nails, the 56th Division prepared dozens of poison gas bombs.

However, there are some restrictions on the use of poison gas bombs, for example, the wind direction was blowing in the direction of the Japanese army before, and in this case, if the poison gas bombs are fired, the mountain wind will blow in the direction of the Japanese army.

So Masao Watanabe had no choice but to wait, and while waiting, he also let the 56th Division rest for a while and replenish some ammunition.

This is also the reason why the Japanese attack was not ** and the number of people was relatively large.

If you want to shoot the gas cannon, there is no need to waste shells, and after the gas cannons are fired, those high ground is determined to win...... That's just rushing up and getting rid of the Chinese soldiers who were poisoned on the ground one by one. These more than 300 men were sent to occupy Heights 159 and 311 respectively.

Of course, Masao Watanabe did not expect that the Chinese army at this time would also change its tactics and prepare for it in order to save ammunition.
