Qin Chuan will know this because this kind of "mobile defense" is a trick often played by the Germans.

This can also be said to be forced: after World War I, Germany's Wehrmacht was limited to 100,000 men, and in order to deal with the threat of superior enemy forces on the Western Front, they developed a different model from positional defense...... Mobile defense.

It is characterized by the formation of a local superior force to defeat the enemy during the movement when the number of its own forces is insufficient. The key requirement is your own "mobility capability". (Note: Many people think that this is a tactic invented by the Germans, but in fact, there are many examples of "mobile defense" in ancient China, such as the combat method of the Mongolian cavalry and the way the famous general Meng Heng of the Song Dynasty resisted the Mongolian cavalry)

This groundbreaking tactic proved to be correct, and in World War II, the Germans were often inferior in strength and equipment to their opponents, but they were able to rely on rapid maneuvering like "lightning" back and forth, so that they could not only attack the enemy's weak points, but also exert the combat effectiveness of the troops as quickly and as quickly as possible.

On the other hand, the British army, due to the slow speed of tanks and the small number of mechanized troops, seemed to have sufficient troops, but in fact there were not many troops on the battlefield at the same time...... Many troops did not arrive on the battlefield until the battle was over, and these units that did not play a role were practically non-existent.

Qin Chuan guessed correctly, the British army did disperse their forces across the entire defense line to attack Tobruk, and their purpose was to disperse the German army as much as Werner said.

But Colonel Slein, as a veteran of the First World War, knew that the defense could not be dispersed, otherwise only 33 soldiers could be allocated in a mile, that is, only two soldiers in a hundred meters...... This almost means that there are loopholes everywhere.

Colonel Slein's response was to make the most of Tobruk's inexhaustible ammunition...... He threw himself into the defensive line with only one battalion, and the German machine gunners in this battalion had all been rearmed with British Bren machine guns and Vickers heavy machine guns, which allowed them to fire a large number of bullets at any suspicious point in the bunker, and then there were anti-tank guns in the bunkers, combined with trenches, barbed wire, mines...... From time to time, a few flares would hit the air, and the British could not move an inch at any point.

Colonel Slain, on the other hand, personally led the three battalions as mobile units within the Blue Line, which were distributed in three directions of the line of defense in companies, about 12 kilometers apart, and the three companies divided the 30-mile (48 km) line into four sections evenly.

Armed with a large number of armoured vehicles and automobiles, the carriages of the vehicles were loaded with ammunition and some of the howitzers captured from the British warehouses, and if there was an emergency in any section of the line, such as when the British attacked under the cover of tanks, one or two mobile units would soon arrive at the corresponding positions to counterattack the Germans.

But even so, the mobile unit was very busy under the attack of the British army, because the British attacked from one direction and the other from that direction, which made Colonel Slain a little tired.

In fact, Colonel Slein and even Qin Chuan underestimated Major General Evans, the commander of the 15th Armored Division of the British Army.

All this was a feint for the British, and its real offensive force was actually located in a passage to the southwest...... Sappers always build such a passage when laying mines, so that their withdrawn troops can quickly and safely pass through and enter the defensive line, and then the sappers will fill the passage with mines and barbed wire.

Moreover, in order to prevent the troops from being detected by the enemy and being blocked by fire, such passages are often built in relatively secret and difficult to find places.

There was also such a passage in the Tobruk Line, but the sappers stationed in it hastily replenished some mines in the passage when they knew that it was the Germans and not the British who were coming, but this did not affect Major General Evans's plans.

"This passage is in the low-lying area of this part!" Major General Evans pointed to the map and said to the staff officer: "It has a small sand dune on each side...... In fact, they can only be called small dirt bags, but the more they do, the less they will attract the attention of the Germans! ”

The staff officer's eyes couldn't help but light up: "Great! We can attract the enemy's attention with a frontal attack, drown the sound of the tank's motor with the sound of artillery, and then send a force along the passage to break through the enemy's line of defense and crush it from the inside! ”

Major General Evans shook his head: "We can't do that, Barrett!" ”

"What?" Hearing this, the staff officer couldn't help but be puzzled, this was a golden opportunity to defeat the German army, but Major General Evans said "this can't be done".

"Think about it, what would happen next if we crushed this German army?" With that, Major General Evans turned and walked over to the improvised table made of shell boxes and made himself a cup of coffee.

"They'll run away!" The staff officer said.

"What else?"

Under the reminder of Major General Evans, the staff officer couldn't help but say "oh": "They will flee back to the port of Tobruk and then fight with us in the streets, which will cause us a lot of trouble......"

Evans almost didn't squirt out the coffee in his mouth, he looked at the staff officer with an incredulous gaze and asked, "Barrett, how did you become a staff officer and get the rank of colonel?" ”

The staff officer couldn't help but be a little embarrassed, because he did rely on family ties to get to this point.

"What's the problem? Checkmate! The staff officer asked with a red face.

"Barrett!" Maj. Gen. Evans did not answer and asked, "What do we need most?" ”

Only then did the staff officer suddenly realize: "Supply!" You mean supplies located in the port of Tobruk! ”

"Yes!" Major General Evans nodded: "If we just crush the Germans...... All we get is a pointless defensive line, a pile of corpses, and a ruin, and the Germans have plenty of time to blow them up, and without them, do you think we'll be able to handle the battle that follows? The main forces of the Germans are still in Maychile, and they will not let us go! ”

The staff officer couldn't help but nod when he heard this.

You must know that the total strength of the British army is more than 100,000 people, not counting those auxiliary personnel, all of whom need 1,500 tons of water just a day, not to mention fuel, ammunition and the like.

Thinking of this, the staff officer's face became solemn, and he realized that the Germans would probably only need to light a match to defeat the British army on all fronts.

"So!" Major General Evans said: "This force will break through the line and go straight to the port of Tobruk, where we have information that the Germans have only one infantry company......"
