In a conference room in the Governor's Mansion of Kangshui City, the capital of Luochuan Province, Su Yi asked He Yunfei and Cheng Ziwen, "Do you have any specific battle plans for the more than five million enemy troops in the Dingxincheng area, Fuyangcheng area, and Anzhou City area?" ”

Cheng Ziwen immediately said: "Marshal, we will put one Guards Infantry Brigade and seven field infantry divisions in the Dingxin City area, two Guards Infantry Brigades and fifteen field infantry divisions in the Fuyang City area, and one Guards Infantry Brigade and eight field infantry divisions in the Anzhou City area. ”

Su Yi nodded and said, "Then implement this battle plan you formulated!" Does anyone have anything to add to the ensuing war? ”

He Yunfei said at this time: "Marshal, I think that in the next operations against the Dingxin City area, the Fuyang City area and the Anzhou City area, the attack should not pursue the width, but the depth, we should concentrate the powerful artillery firepower, in the front of three kilometers to five kilometers, the enemy's entire depth of fire suppression, and then quickly penetrate the enemy's entire defense area, and then put in follow-up troops to expand the results, so that we can really give full play to the power of the pincer offensive, if we first concentrate firepower to hit the enemy's front defense line, After consolidating the results of the battle, we will gradually advance and soon be able to let go of most of the enemy forces in the above three areas. ”

Su Yi did not serve as a soldier for 12 years in vain in another world, and Su Yi understood that the offensive tactics mentioned by He Yunfei are known on the earth as the theory of large-depth campaigns, which were put forward by the Soviet army in the thirties of the 20 th century on the basis of summing up the lessons and lessons of World War I in order to adapt to the development of weapons and equipment, and are an important guiding ideology for carrying out offensive campaigns.

The theory of large-depth campaigns emphasizes the use of lethal weapons to suppress the enemy's entire defensive depth, break through the enemy's tactical defense area in the selected direction, and then quickly turn the expansion of the results into engagement, and quickly develop the tactical victory into a campaign victory, so as to achieve the predetermined goal as soon as possible.

Su Yi frowned and said: "This kind of large-depth tactics has great requirements for troops, if the follow-up troops can't keep up, the troops in front of the assault are likely to fall into the enemy's heavy encirclement, you must know that our Su family army has only invested a total of forty field infantry divisions and four guards infantry brigades, and the strength is comparable to the combined forces of the Shalad Empire and the Cangyu Empire, but it is at a disadvantage, but the specific tactics have to be decided by Yunfei and Ziwen, if you think this kind of large-depth tactics is okay, I will not object, I don't ask for the process, I just hope for results. ”

He Yunfei and Cheng Ziwen looked at each other, and both nodded slightly, and then Cheng Ziwen said: "Don't worry, Dashuai, even if something goes wrong with this large-depth tactic of quickly penetrating the enemy's entire defense area, with the powerful firepower of our Su army's artillery unit, we can save the situation back, so Yunfei and I both decided to try the large-depth tactics, if the large-depth tactics can really work, then the more than five million enemy troops in the Dingxincheng area, Fuyangcheng area and Anzhou City area will basically not run." ”

From the beginning of the Su family's sudden attack on all fronts, the bad news spread one after another to Feini City, the capital of the Shalad Empire, and Cangyu City, the capital of the Cangyu Empire.

In just fifteen days after the start of the war, the Su family army broke through to the territory of the Cangyu Empire for almost 200 kilometers, and surrounded the two Shalad Empire infantry legions and two Cangyu Empire infantry legions in the Dingxin City area of Southern Hebei Province of the Cangyu Empire.

It also surrounded three Shalad Empire infantry legions and two Cangyu Imperial infantry legions in the Anzhou City area of Lunan Province of the Cangyu Empire.

Only in the Fuyang City area of Hongshan Province of the Cangyu Empire, the Su family army did not complete the battle plan formulated.

The four Shalad Imperial Infantry Corps that were originally in the Fuyang City area, under the leadership of their commander-in-chief, Slava, the commander of the Second Infantry Corps of the Sharad Royal Army, quickly withdrew from the Fuyang City area, and as a result, the Su Army troops of the two Guards Infantry Brigades and fifteen field infantry divisions only surrounded the four infantry corps of the Cangyu Imperial Royal Army in the Fuyang City area.

And the commander of the Second Infantry Regiment of the Royal Salad Army, Slava, actually did not perceive the Su Army's attempt to prepare to encircle their four Royal Sharad Army Infantry Corps, and the reason why Slava retreated so resolutely was because the artillery unit of the Su Army blew up all the large-caliber artillery of the four Salad Royal Army Infantry Corps.

After receiving the combat order from the War Department of the Shalad Empire, that is, at 8 o'clock in the morning of May 22, after launching a preemptive attack on the Su army in the territory of the Purple Moon Empire, Slava gathered thousands of large-caliber artillery pieces from the 2nd Infantry Corps, the 11th Infantry Corps, the 26th Infantry Corps and the 27th Infantry Regiment of the Salad Royal Army to form several huge heavy artillery groups, including 75 mm field guns, 75 mm infantry guns, and 105 mm howitzers, 127 mm howitzer and 155 mm howitzer.

However, what Slava never expected was that the Su army launched an attack two days in advance, and after the attack began, it quickly used intensive artillery fire to turn over all the heavy artillery group positions of the four Salad Royal Army Infantry Corps several times, detonating tens of thousands of tons of shells, and as for the fate of the thousands of large-caliber guns of the four infantry regiments, it can be imagined.

Without the suppression of large-caliber artillery, Slava did not think that the four Salad Royal Army infantry corps could block the attack of the Su family army in the Fuyang City area, before in the territory of the Purple Moon Empire, Slava had already learned the power of the Su family army, as for the four Cangyu Empire infantry regiments that were also stationed in the Fuyang City area, Slava only regarded them as a burden.

The four infantry regiments of the Royal Army of the Cangyu Empire combined, there were only more than forty guns over 75 mm, and the weapons in the hands of the soldiers were still mainly outdated breech single-shot rifles.

When Slava led the four Sharad Royal Army infantry corps to retreat, he gave the four infantry corps of the Royal Army of the Cangyu Empire an order to hold their positions, and it was precisely because of the four infantry corps of the Royal Army of the Cangyu Empire that the four infantry corps of the Royal Army of the Cangyu Empire were able to successfully withdraw from the Fuyang City area, but the four infantry corps of the Royal Army of the Cangyu Empire were surrounded by the troops of the Su Family.

Under the fierce offensive of the Su army, the army of the Salad Empire and the army of the Cangyu Empire, which were stationed in other areas of the Cangyu Empire's southern Hebei Province, Hongshan Province, and Lunan Province, were also defeated all the way, which made the two armies besieged in the Dingxin City area, Fuyang City area, and Anzhou City area suddenly become isolated and helpless.
