Engel proclaimed himself a thoughtful and calculating "wise general", and of course he carried plenty of shells and spare barrels with his army for "Old Charlie" to continue to fire. In fact, in the eyes of most of the generals who participated in the Eastern Crusade, these reserves were most likely to be useless. On the other side, not everyone in the Far East defenders has a strong will as steel, and how can they be calm when they see their positions being ravaged by Imperial trains, and the fortifications they have painstakingly built are being pulled out one after another? There was no need to destroy all the pillboxes, and the Far Eastern defenders would be so frightened that their fighting spirit would collapse and they would retreat on their own. The Imperial army was able to calmly cross the river under the cover of train cannons and strode in the direction of the Fort of Atonement. If all goes well, in no more than four weeks, the four "Old Charlies" will be able to uproot all the rebel strongholds along the way and approach the city of Fort Atonement, and then replace them with more expensive and destructive "infusion dissociation shells", and a single salvo can blast through the city's defenses, opening a passage for the Imperial cavalry to wave their troops into the city.

At the same time that the Imperial Train cannon drove into the Olevi Fortress, the people on the platform were unaware that a cold wind was blowing in the gloomy sky overhead. The 1st Squadron of the Carrier-based Aviation Wing of the Destiny, the flagship of the Fifth Fleet of the Far East Air Force, was conducting reconnaissance over the Olevy Fortress at the moment. Air Force Captain Abigail and his Giant Eagles all took the "Invisibility" potion in advance, relying on the sharp eyesight of the Giant Eagle Clan, overlooking the snowy fields from a cloudy sky, as early as two days ago, they noticed the unusual behavior of the Imperial Engineers, so they intended to strengthen patrols near the platform.

Captain Abigail's hard work was not in vain, early this morning, when the roaring magic train dragged four heavy guns into the platform, the eagles in the air stealth reconnaissance immediately became aware of it, and reported to Captain Abigail as soon as possible with the help of the "magic guide intercom".

Half out of professional necessity and half out of personal interest, Captain Abigail always wears a military high-powered "photoscope" around his neck, and if he finds anything unusual, he will quickly photograph it for archival purposes. Today was no exception, Abigail ventured to lower his flight altitude and hover low above the station, circling in circles to take a closer look at the four train guns, and everything he saw was captured in a "mirror".

Later in the day, Captain Abigail returned to the mothership Destiny with his reconnaissance harvest to report back to Lieutenant Commander of the Fifth Fleet, Lieutenant Commander Yelena, and his immediate superior, Rear Admiral Aurora, Commander of the Fifth Fleet Air Force.

Yelena and Aurora immediately realized the seriousness of the situation, and immediately took Abigail to the "Cold Creek Town", where the headquarters of the Western Front garrison was located, and personally reported the enemy situation to Marshal Pavel.

Marshal Pavel once followed Rudolf I on an expedition to the fortress of Dragon City on the Lucia Plateau, and witnessed the great danger of train artillery in the battle of positions, and he was deeply impressed by the seemingly impregnable front-line fortress group of "Dragon's Eye", which was completely vulnerable to the roaring cannons, and collapsed in just one day.

Marshal Pavel carefully looked at the ** film of the train taken by Captain Abigail, and compared with the two train guns owned by the military in the Far East, he had to draw a pessimistic conclusion.

Regardless of the caliber of the barrel, the firing range or the pound of the shell, the emperor's "Old Charlie" is superior to his own "Roland's Hammer", and the number is twice that of the latter. The current situation is obvious, the emperor can set up four train cannons twenty miles away, so as to bombard the fortifications on the banks of the Far East River in a whole time, and any of his magic crystal cannons, including the "Roland Hammer", can not fight back at such a distance, and is in the dilemma of being beaten passively.

In the afternoon of the same day, Marshal Pavel summoned his generals and staff officers to the headquarters for a meeting to discuss countermeasures against the threat of imperial train artillery, and finally formed two plans.

The first plan was more radical, put forward by Air Force Colonel Yelena, and was strongly supported by General Jennifer, deputy commander-in-chief of the Far East Air Force and commander of the Fourth Fleet, and the main purpose was to take advantage of the superiority of the Far East Air Force to choose a time when the snow was falling heavily and the light was dim, and the Fourth and Fifth Fleets of the Air Force, with a total of six airships, under the cover of more than 2,000 air forces, carrying heavy bombs, jointly launched an air attack on the Imperial train gun position, striving to blow up all the train guns, so as to free the riverbank defense line from the threat of giant artillery.

There are two reasons why this proposal is radical. First of all, the air raid operation must be carried out as soon as possible, once the enemy gets the news and moves the train guns to the interior of the Olevi fortress, which is protected by the locks, the air raid operation will not be possible. Second, because the authorities in the Far East had to deal with operations on both the southern and western fronts at the same time, the air force ships had to be divided into two routes, the first, second, and third fleets had already been transferred to southern Xinjiang, and only the fourth and fifth fleets remained on the western front, which had little advantage over the air defense forces stationed in the Olevi fortress, and in addition, the main fleet of the imperial air force was stepping up its dispatch to the Far East, and there was still very dense anti-aircraft fire on the train gun positions, and even if the surprise operation was successful, it would have to pay huge losses.

Compared with the overly aggressive air raid operations proposed by Yelena, the plan proposed by Kalinin, commander of the Far Eastern Chasseurs and commander of the lieutenant general's division, is too conservative. General Kalinin judged the hour and sized up the situation, holding that at present, the Far East should focus on making every effort to ensure the smooth progress of operations on the southern front, while the western front should focus on defense, and that it should try to avoid the loss of such important strategic resources as air force ships and carrier-based aviation.

"The enemy's train artillery is indeed very powerful and has a long range, but there is also an insurmountable weakness, that is, it is too bulky, if the cross-river railway bridge is destroyed, it will be difficult for the emperor to transport these heavy train guns across the river, and it will no longer be able to pose a threat to our army's rear positions. In view of this weakness of the train artillery, when necessary, our army may take the initiative to withdraw the garrison troops, blow up the bridge of the Zhuolang River, and lay mines along the river bank to slow down the pace of the imperial advance, which is more in line with the strategic policy of 'exchanging space for time' put forward by His Royal Highness the Regent. ”

"The contraction of the Western Front is by no means an escape, but in order to concentrate resources to support the offensive on the Southern Front, we now withdraw our fists so that we can strike the enemy more forcefully in the future! When the battle on the Southern Front is decisively victorious, and the Southern Army Corps moves to the Western Front to make peace with our troops, our army will gain an overwhelming advantage over the Imperial Crusade troops. ”
