On the night of May 2, 1949, the Great Belt Strait, Denmark.

The moonlight reflected the sea, and in the undulating waves, a periscope, not much bigger than a canned box, quietly peeked into the distance as ships passed between the two sides of the strait. For hunters who have been lurking underwater for a long time, passenger liners and cargo ships with clear silhouettes and stable trajectories are the best prey, but those agile escort ships are like vigilant sheepdogs, guarding their own flocks every step of the way. If they were piloting a cutting-edge attack submarine, the Red Navy soldiers would not hesitate to use torpedoes to sink all the targets, but they were operating an "prestigious" old submarine, which was slow and noisy, and barely played the role of observers, and had to wait for the enemy to show flaws before they had a chance.

In the command cabin of the submarine, the scumbag-faced captain curled his tongue and said quickly: "It is not surprising that greedy US imperialism has no faith to speak of, and for its own selfish desires, let alone cooperating with the evil remnants of the Nazis, even if it concludes a close alliance!" ”

Ying He, an officer who assisted in the observation, said: "At that time, we should not have signed any armistice agreement with them, gritted our teeth to break through their Western European defense line, and completely smashed the Western alliance. ”

The captain snorted coldly, and the topic was stopped.

"It's been almost two hours." The officer looked at his watch, "I guess the fleet command is eagerly awaiting our latest report!" ”

The captain said uncertainly: "More than 40 transport ships, 10 nautical miles wide strait, two hours is enough to transport a fully armored infantry division to Jutland." In one night, the Germans would have enough to bring 100,000 men ashore, and by daybreak Marshal Chuikov's armored forces would wipe them out like garbage. ”

Not only the officers, but also the crew members next to him will smile, they have long been accustomed to victory, they can also maintain full optimism in the face of adversity, for him. The nail encountered in the Upper Rhine Valley was only a special case, and on the battlefield of the whole country, the Soviet soldiers were still invincible.

After about half an hour, the captain saw in the periscope the nearest enemy escort ship cruising in the opposite direction, and ordered the submarine to float. In the moonlight, the sleek black shark merely exposed the conning tower, its sides painted with the battle number 310.

SHCH-310, a Barracuda-class attack submarine belonging to the Baltic Fleet of the USSR Navy. The mini-submarines, built from the thirties, were outdated during World War II, and in 1945 the Revolutionary Military Council of the Soviet Union drew up an ambitious plan for the development of a navy that would completely phase out the older ships built in the early days within five years, but the Soviets' ambitious naval plans were only possible in peacetime. In the ensuing outbreak of World War III, the Allied air forces carried out a continuous large-scale bombing of the Soviet Union, causing great damage to the Soviet industrial infrastructure. Without outside assistance, the Soviet military had to use scarce industrial products for the most urgently needed equipment on the battlefield - fighters, tanks, and ammunition had already consumed most of the metal, and the priorities for naval construction were placed far behind. From the outbreak of the war in 1946 to the signing of the armistice with the Allies in 1948, the Soviet Navy lost 170 ships of all types and received less than 70 ships, including Allied ships captured by army forces in battle.

The naval construction was weak, and the officers and men of the Soviet Navy had no choice but to continue to fight with old and outdated ships. Fortunately, the land forces of the allies were far less powerful than the Third Emperor's ** team, and they had no chance to approach such strategic towns as Moscow and Leningrad, and even the time for their activities in the southwestern region of Russia was very short. Under these conditions, the forces of the Soviet Baltic Fleet were able to be preserved in the face of the incomparably powerful Allied Navy, which for most of the time was scattered and hidden in various ports in the depths of the Gulf of Finland, and only later in the war gradually returned to the central Baltic Sea. But unlike at the end of World War II, the Soviet Navy rarely took the initiative to attack because of the strong presence of Allied sea power, and the Königsberg nuclear bombing may be their only commendable victory ..........

As soon as the submarines moved from full to semi-submersible, the mediocre Soviet-made radio stations began to work, reporting what they had observed here to the Baltic Fleet Operational Command in Danzig Bay with the shortest possible signal. The operational command also included another 21 submarines and more than 40 torpedo boats suitable for rapid assault operations in the coastal waters, which could theoretically quickly mobilize these naval forces to attack enemy ships crossing the strait. The bright moonlight also provided a certain convenience for the night bombing of the air forces, but judging by the "silence" of the combat command, it was obvious that the superiors were happy to see the opponent move from the island to the land, and only in this way would the Soviet army, which was firmly in the position of the world's largest army, have a chance to exert its might.

The telegram was quickly delivered, and the surrounding sea seemed to be in good shape. But suddenly, there was a rumbling cannon sound in the distance, and in the blink of an eye, one shell after another whistled in, landing near the submarine and a violent explosion, the crew who were observing the vigilance on the control tower hurriedly got into the cabin, and with the appearance of a ball of bubbles around the hull, the thick fins of the "Black Shark" quickly disappeared from the water, and the artillery fire continued for a while, and it quickly subsided.

On the same night, Lynn, who was sneaking underground, was similarly disturbed. As he feared, the Soviets not only brought in the brave and skilled ace corps, but also the attacking troops were equipped with night fighters, and the American-made night combat equipment they used was comparable in performance to the "Vampire" night vision devices, and in the first half of the night in the two assault operations, Lynn and his soldiers were quickly hunted by their opponents, although they carefully hid their whereabouts, and they had to retreat to the underground world through the sewer entrance due to the absolute disadvantage in numbers and firepower.

Things don't go well, everything doesn't go well, Lynn has felt this way in her past life, and now that she is on the battlefield of real knives and guns, irritability is not something that alcohol or sleep can paralyze. Listening to the heavy gasps of his subordinates in the dark, he took the crumpled cigarette from his pocket and rubbed it back and forth under his nose for several minutes before he put away the cigarette and took a deep breath of the rather turbid air:

"Guys, the enemy is obviously well prepared for our night assault tactics, so this battle will be much more difficult than imagined, and perhaps we will be willing to succumb to the fear of our hearts, and hide in places where the enemy will not find out for a while, but think of our lives, ninety-nine percent of the time with our heads held high, and one percent of cowardice is a stain on ourselves! Come on, let's try again, try harder, even if we die, we will not regret this proud life of fighting! ”

The faint hope, the tiredness of body and mind, the oppressive atmosphere, the soldiers had every reason to refuse to fight or react passively, but none of them flinched, and none of them complained. By the time Lynn had chosen a route leader to set out, everyone clutched the weapons in their hands—they were no longer the most advanced and increasingly difficult to take advantage of under reciprocal conditions, but they were always reliable partners on the battlefield, and their presence kept hope alive at all times.

Lynn's back was already soaked with sweat as he walked four or five kilometers through the intricate sewers, and when he stopped to listen to the movement outside the well, the sound of his heartbeat was overwhelming. There was no roar of tanks, no roar of artillery, no clash of footsteps, but Lynn couldn't predict if there would be a black hole waiting for him outside until he opened the manhole cover at the mouth of the sewer, but he chose to take the lead.

Knowing that the manhole cover was not a primeval forest full of poisonous insects, an ignorant indigenous tribe, and a mysterious alien planet, but when he carefully pushed it away, Lynn's heartbeat accelerated to the extreme, and the invisible pressure almost made him breathless.........

The dancing firelight, the dark streets, such scenes have appeared countless times in midnight dreams. Quickly scanned the circle with the infrared detector, risked being shot in the head by a cold gun, climbed straight out of the mouth of the well, and moved sideways for several meters, and when his arm leaned against the broken wall, Lynn seemed to have walked before the ghost gate closed. However, the dangerous battlefield did not leave him a moment of respite, the echoing gunfire in the neighborhood kept his nerves in a state of high tension, and the innate sense of position that made him a first-class night raider drove Lynn to move towards the alley like a civet, the sound of hurried footsteps approaching quickly, these Soviet soldiers may have noticed the situation and hurried, or maybe they just happened to pass by, but no matter where they came, Lynn and his soldiers could not leave anything to chance.

With the left leg bent and the right knee on the ground, the side is close to the wall, the left hand makes a continuous gesture to give the command to the companion to engage the enemy, and then retracts the grip guard, the right hand opens the bolt safety lightly and accurately, and the assault rifle is raised smoothly and quickly with both hands, the right eye is just level with the infrared scope, and the left eye is open at the same time to maintain the largest possible field of view. Soon, the footsteps outside the alley were getting closer and closer, and even the gasps of the runners could be heard clearly, and at this moment, Lynn had adjusted herself to the realm of spring, and it only took a short moment from tension to release.

As if sensing imminent danger, the clearest footsteps suddenly slowed down, and in a state of concentration, Lynn heard the subtle sound of clothes rubbing against the wall—both behind and from ahead. At this time, he didn't need a small mirror to know that the other party was slowly approaching the alley along the house wall, and he must have a firearm in his hand that could be fired at any time, just like himself. The exchange of fire may be in the next second, and Lynn has no chance to turn back to confirm the status of his companions, even if they don't see their gestures and all of them are out of position, they can only go into battle without hesitation.
