Zhang Tan had no choice but to give the order to evacuate, and if they did not retreat, their defense line would definitely be chaotic without a fight.

All advancing territories are temporarily withdrawn and returned to Imperial control.

The 12-hour rest that had been planned was terminated, and the 600,000-strong coalition troops, devastated by the Empire, were severely overdrawn mentally and physically.

Such an army would not be able to sustain combat, and if it wanted to fight, it would have to reorganize its troops. If they can't counteract the constant Imperial noise, the coalition will lose the war against the Empire.

The retreat was not approved by the major leagues, and it took several hours to wait for the permission of the major leagues, and a lot of unpredictable things could happen in a few hours.

Zhang Tan used his decision, and all the participating countries and the troops under his command withdrew from the territory of the empire, a distance of 200 kilometers.

The position of the original headquarters was also moved backwards, and all the nations retreated evenly.

Every move on the front line can be reported to the superior leadership by the battlefield supervisors of the big alliance, and the angry big alliance wants to remove Zhang Tan, who is in command of the disorder, even if the troops are attacked and disturbed, insisting on persistence can always be overcome. And Zhang Tan not only did not overcome it, but ordered everyone to turn back, and this turn actually ran 200 kilometers.

Running is not too far, two hundred kilometers is no longer a limited retreat, he has exceeded the maximum distance of the strategic offensive. Doubts about Zhang Tan sounded again, and more people wanted to remove the disobedient former commander-in-chief.

Fortunately, at the last moment of the recall, most of the front-line troops were willing to intercede for Zhang Tan, at least Zhang Tan made the most correct choice in the most correct time period.

Retreating is the best option to save them from the danger of annihilation.

Zhang Tan didn't have time to deal with a group of people who were blindly commanding in the base camp behind the formation, and at this time, he needed to provide more useful noise-canceling headphones for the attacking troops as soon as possible.

The noise-canceling headphones currently used cannot effectively overcome the effects of external noise, and poorly rested soldiers are already in a state of extreme mental exhaustion.

Zhang Tan's requirements are not high, and the scientific and technological personnel in the rear can quickly solve the front-line problems, but it takes time to produce in production.

The superposition of the two time points is sent to the front-line troops, not to mention a week, it is impossible for people to survive in a noisy environment for a week, and if the GIs are really allowed to live for a week, what terrible things will happen are unimaginable. The former general decided to retreat back two hundred kilometers again, four hundred kilometers far beyond the maximum attack range of the Imperial sonic weapons, in order to ensure that all the troops participating in the battle would not be disturbed.

Retreated four hundred kilometers and again did not apply to the Grand League. Zhang Tan's reason is still 100,000 urgent, and he can't apply to the rear in time.

The retreat was relatively orderly, not pursued by the Empire, and not a single army was annihilated by the encirclement of the country due to the retreat.

A successful retreat became a miracle in history, and the entrenched forces formed several impregnable fortresses.

After completing the great retreat, the next task is to prepare for a counterattack, and you can't retreat again and again, and you will let the empire attack you.

Fortress defense circles have been formed, relying on each other, and at a distance of four hundred kilometers from the empire, countless cities of different sizes and soldiers have been formed.

The remaining coalition forces took an all-defensive posture and allowed the outside empire to harass. The original noise will no longer pose a threat to the coalition forces, leaving a 400-kilometer gap in defense, and if there is any missile attack, there will be enough time to intercept the incoming missiles, and the noise generated by the interceptor missiles will not endanger the ground personnel.

The coalition forces had a steady stream of reinforcements, and secret weapons were secretly sent to the front-line troops.

It turned out that he wanted to rest for two days and then advance towards the empire.

However, due to the overly chaotic forces, it was not wise to attack at this time, and although the troops were large, they were too chaotic.

Who can reorganize the multinational force has become a difficult problem for Zhang Tan for a while.

He didn't have the ability, not only were the number of troops large, but everyone spoke different languages and different living habits, and an order needed to be translated into dozens of languages.

Systematic orders like Zhang Tan are well solved, and all officers and soldiers are equipped with synchronous translators who can provide them with even translations.

Instant translation has limitations, there is a delay in time, and the accuracy of translation is not high, and what is more fatal is that there will be a certain delay in translation.

The delay of war in which every second counts is simply devastating, creating opportunities for the opponent to overcome himself.

Although the coalition forces are numerous, it is not easy to condense a rope.

In the end, Zhang Tan came up with a compromise solution, the country that can directly understand the command is in the first-line position, and if the country can find a synchronous interpreter, it can also enter the first-line position.

However, there is no one who can accurately translate at the same time, and the participating countries must be transferred to the second or third line of troops to carry out combat missions that do not need to be reported on the battlefield situation at all times.

The simple points can meet the current needs, and in order to better complete the rest of the attack missions, the rest time has been extended to 12 days by Zhang Tan.

Spend twelve days teaching the stupid troops how to understand the command, so that they can learn to respond to the attack of the main force. Otherwise, it really opens, and God knows what level the newly joined coalition forces are.

For twelve days, the main force rested, and the follow-up troops entered the devil's training stage.

Twelve days was not an easy one, and the major leagues were still being attacked by varying degrees of attack. The Empire combines sneak attacks, noise, and truncation to attack the innermost forces of the Empire.

The innermost side was subjected to the most difficult twelve-day defensive battle, which was the first time that Zhang Tan had issued an order to defend to the death after the start of the war. Resolutely complete the task of holding on, and the first layer of encirclement will not be allowed to be broken.

Zhang Tan ordered all the defense troops involved in the internal level to defend to the death, and resolutely not let go of a single enemy who broke through.

The innermost troops need to buy time for the final victory at all costs, preferring to have only one position left and still make sure that the position is in the hands of the coalition forces.

The commendable holding force carried out the order perfectly, not only did not lose an inch of the defending ground in twelve days, but also did not let go of a single soldier of the attacking force.

The results worth boasting of, the holding troops paid a price of one-fifth of the casualties. After holding out for twelve days, the innermost defensive force has been beaten into a half-crippled army.

After carrying out the 12-day defense, Zhang Tan was immediately withdrawn from the front line of the battle, transferred to the rear for renovation, and continued to devote himself to the front-line attack force after replenishing the full force.

Twelve days had come at a terrible cost, and the coalition had discovered the weakness of the Empire's attack. The Empire's largest attack can only reach its current state, and its attack power is nothing more than that. Although the empire is holding on to a certain doorway, his attacks are no more than that.
