Strictly speaking, this should be a "tunnel war" and not a "tunnel war".

The two are very similar in form, both are digging pits underground, but in fact there are differences.

The biggest difference is that the tunnel of the "tunnel warfare" is built on the high ground, and there is only one tunnel mouth exposed outside, and the main body of the tunnel is inside the high ground, and it is difficult to dig the tunnel from the outside due to the nature of the high ground.

"Tunnel warfare" is generally built on flat ground or high ground, and it is easier to find tunnels if you know where they are going and dig down from the outside.

Therefore, there is a big difference in their combat methods, for example, "tunnel warfare" is to use the tunnel mouth to cover each other, use the high ground to achieve "hiding troops", "maneuver", and combine with the anti-slope position to fight.

And "tunnel warfare" is to use the buildings on the surface to hide the tunnel entrance for mobile warfare.

Of course, Qin Chuan's use of the tactics of "tunnel warfare" here was not to rely on this tactic to fight the Soviet army, but to be forced by the Soviet army and the cold to be a little helpless.

Once the chimneys were in place and proved to be effective, the morale of the troops was quickly improved.

Originally, everyone, including the soldiers of the First Infantry Corps, had a negative attitude towards the war...... They are not to blame for this, thousands of people occupy a small piece of high ground and are surrounded by Soviet troops outside, and the Soviets have tanks and artillery, but the Germans have nothing.

The huge disparity between friend and foe is obvious, especially at night when you can't light a fire, the food you eat is cold, and you can't sleep...... If you go on like this, not to mention fighting, you won't need to freeze or get tired for a few days, and the game will be over soon.

But now, as soon as the chimney is ready, the fire can be baked, and the cellar is as warm as a greenhouse, and it is a good place to rest and sleep, and of course you can eat hot food with a pot.

The soldiers' requirements are actually quite simple...... The problem of food and clothing is solved, and the problem of sleep is also solved, so even if you die on the battlefield, you will die comfortably.

On this basis, of course, it is not a problem to let the soldiers carry out tunnel transformation.

The tunnel renovation does not look difficult on the surface, the houses in the town are not far from each other, and the distance between them is more than ten meters, that is to say, only the direction is right, and the tunnel is dug more than ten meters deep from the flank.

But it's not that simple.

The first is the fear of collapse...... The cellar is very close to the ground, and most of them are made of cement concrete, so there is no worry about collapsing, but if you dig the tunnel directly from the side wall, the thickness of the soil layer on the tunnel is only afraid that it is not even one meter, which will cause the tunnel to collapse if a few shells are shaken or hit.

In order to avoid this problem, instead of digging the tunnel directly from the side wall, it is first hit downwards and then extended in the direction of another cellar.

"Be careful not to extend in a straight line!" This is Qin Chuan's authentic requirement.

Colonel Slein asked puzzledly, "Why can't it be straight?" Our tunnels all seem to be straight, but with a few corners! ”

"A tunnel is not the same as a tunnel!" Qin Chuan replied: "The tunnel is easier to defend, and there is basically no situation where the tunnel is occupied by the enemy!" But authentic...... If you make it in a straight line, once the enemy captures one of the cellars, it only takes one machine gun to threaten everyone in the other cellar! ”

Colonel Slain couldn't help but nod his head in agreement.

So, the tunnel was built into an arc, like an arched bridge, from one cellar to another, and from another cellar to more cellars, and some to trenches, hospitals, or other places where it might be possible to go in time of war, as if it were an underground city.

On the other hand, the promised supplies from the army headquarters arrived as scheduled in the afternoon...... First, two fighters and four fighters bombarded indiscriminately against Soviet artillery and anti-aircraft fire, and then six transport planes "rumbled" over Holm.

The Soviets immediately realized that these transport planes were trying to parachute in for supplies, so they fired hard at these transport planes with light and heavy machine guns and anti-aircraft fire.

A transport plane engine was hit, and black smoke was raised...... However, as mentioned earlier, the nickname of the "Junker 52" in the German army was "Steel Annie", as long as the engine did not catch fire and spread to other places, it was a trivial matter if one of the three engines broke down.

As a result, 6 transport planes successfully dropped 18 boxes of supplies over Holm...... It's just that 6 of them were airdropped to Hexi, which was controlled by the enemy, 2 boxes were dropped to the open space between the enemy and us and could not be retrieved, and the rest of the 10 boxes were dropped to Hedong because the parachute was not opened and crushed, fortunately, there were bags of flour inside, so it did not affect the use.

A box of supplies happened to fall near the second company's station, Qin Chuan and Kuhn, who were stationed in the trenches, looked around and saw that no one else was paying attention, and without saying a word, they rushed up, one of them picked up a bag of flour and ran to the cellar, Yakop followed behind and hugged a few cans, and also ran fast......

These supplies should be handed over to the logistics department for statistics and then distributed, but how can the soldiers who are already hungry because of the lack of supplies take care of this.

When a few men ran into the cellar with flour and cans, they found that Werner had moved a bathtub into the cellar at some point, and that he was already naked, singing and taking a hot shower......

"Sergeant!" Qin Chuan put the bread down on the shell box and said to Werner: "Aren't you worried about the Soviets attacking?" ”

"Then let them wait!" Werner replied: "It's a real treat, Captain, take a hot shower after almost being frozen into an ice sculpture......"

As he spoke, Werner stretched out his long, hairy legs from the tub and struck an ecstatic pose, causing the soldiers to laugh.

"You'd better get this thing out!" Qin Chuan said: "It made the cellar full of moisture, and if the Soviets really attacked...... You'll know what happens when you run out naked and covered in water! ”

"Then the sergeant will really turn into an ice sculpture!" Dominic said, "I just want to know if the sergeant's bird will fly away from the cold!" ”

There was another burst of laughter in the cellar.

"Captain!" After laughing for a while, the baker looked at the two bags of flour that Qin Chuan and Kuhn were carrying in a daze, and asked, "What are you carrying these things for?" ”

"Can't we get something to eat?"

"But we don't have yeast!" The baker said, "And we don't have an oven either!" ”

"God!" Qin Chuan rolled his eyes, it seemed that there was only bread in the eyes of foreigners.
