"Captain, the torpedo tubes have been filled with water, the front hatch has been opened, and it is ready to be fired." The second officer said, "Please tell me where to shoot." ”

"Damn, I can't see the ship anymore." Krezimmer said with chagrin as he operated the periscope.

"Huh? It's gone? So what to do? ”。

Krezimmer thought for a moment, then shook his head and said, "Forget it, just attack the route they took before they disappeared!" The submarine turned to the 0-0-3 azimuth, the torpedo was set to a depth of 3 meters, and three fan-shaped salvos were fired! ”

"Understood, turn 0-0-3, torpedo fan-volley!" The second officer repeated the order, then turned the rudder and steered the submarine to slowly turn to the right, and at the same time, the officers and men in the torpedo compartment began to manipulate the fire control system to set the torpedo in the torpedo tube to a depth of 3 meters.

After the turn, an officer in the torpedo compartment immediately pressed the launch button, and the three-piston device in the torpedo tube was activated, pushing the torpedo inside the launch tube along with the seawater.

After exiting the cabin, the engine inside the torpedo starts automatically, and at the same time, the balance compartment in the mine floats all the way with the torpedo to a depth of 3 meters and then straightens, and the three torpedoes are fired in a fan shape.

After confirming that the torpedo was successfully exited, the officer in charge of firing the torpedo immediately reported to the bridge through the ship's phone: "The torpedo is fired!" ”

"Torpedo tubes reloaded, waiting for the next command!" Krezimmer replied.

"Understood, torpedo tubes reloaded!" The officer answered, and then instructed his sailors to draw the spare two torpedoes and begin refueling.

While the officers and men in the bow torpedo compartment were sweating profusely, a kind of officers in the bridge were also sweating profusely, but they were not tired but nervous, and the U-23 submarine they piloted was Type IIB, which was an improved version of the first type of German submarine after World War I, built in 1936, and was a veritable old ship in the submarine force of the German Navy.

The performance of the IIB submarine is also old, with an underwater displacement of only 328 tons, and the only thing in the whole boat is armed with three 533mm submarine-launched torpedo tubes in the bow, and the torpedoes on board are only two spare in the boat in addition to the three loaded in the tube.

In other words, if Krezimer's salvo misses the target, then he only has two torpedoes left to use, and if the latter two still fail to hit, then he may have to choose to surrender, or go up to the submarine and use a rifle against the enemy's naval guns.

Unfortunately, Krezimmer searched for a long time with a periscope but could not see a trace of the explosion, and the torpedo fired by the three was like a mud cow entering the sea, and there was no movement.

"Damn it!" A few minutes later, Krezimmer patted the armrest of the periscope in frustration. And the other officers also received a lot of blows, one by one.

After taking a few deep breaths, Krezimmer cheered up and cheered everyone up: "Don't give up, guys, we still have two torpedoes, as long as one hit is enough to send the broken ship on the other side to the sea!" ”

"But we don't even know where that ship is...... one officer said helplessly, bowing his head, "I don't know where the other side is, even if we have 10,000 torpedoes, it's useless." ”

"Huh." Krezimmer chuckled twice, "Yes, we don't know where the other side is, but don't forget, the other side doesn't know where we are!" ”

The other officers were stunned when they heard this.

Yes, I don't know where the other side is, but I don't know where I am either!

"Captain, since the other side doesn't know where we are, why don't you ...... Let's run, shall we? An officer suggested.

"Escape?" Krezimmer sneered twice, "I'm not used to that!" No one is allowed to run away from me until the last bullet is fired! ”

"So are we going to spend it like that?" The officer wondered, "We suffer from the light consumption, the oxygen in the submarine is limited, and we will have to surface sooner or later." ”

"Rest assured, we're still close to coming to the surface - at least we'll be underwater until the sun rises tomorrow morning!" "I don't believe it," said Krezimer, "that the moon will not come out once for so long!" ”

As he spoke, he commanded again: "Second mate! Reduce the speed to 3 knots! Notice, the whole ship entered a state of silent submarine, and the people who were not in combat positions gave me back to bed to lie down, and if anyone made half a movement, I killed him with my own hands! ”

"Yes!" The second mate saluted, then stretched out his hand to reduce the output power of the electric motor, and the 42.7-meter-long U-23 submarine dropped sharply under the resistance of the seawater, and quickly increased its top speed from 6.9 knots to 3 knots.

At the same time, an officer tiptoed off the bridge and verbally conveyed the order for a first-class silent dive voyage.

"Turn on the passive sonar." After the last order was given, Krezimmer was silent, and there was no sound in the whole boat, except for the sound of mechanical operation.

At the same time, on the K11 frigate, Finch couldn't help but let out a long breath when he heard the sound of breaking waves approaching the warship at high speed from far and near, and then moving away from him from near and far.

As the captain of a frigate who had been fighting with German submarines for many years, he could tell that it was a submarine-launched torpedo when he heard the familiar voice just now, and he could even distinguish its caliber and model.

The other officers on the bridge looked at Finch with admiration, knowing full well that if Captain Finch hadn't given the order to stop and turn, the torpedo would have split the thin-skinned frigate in two.

"Captain, the hydrophone is cooled." The sonar soldier kept his voice low.

"Turn on the passive sonar." Finch ordered.

"Yes, turn on the passive sonar." The sonar soldier repeated in a low voice, then flipped the switch on the passive sonar, "Passive sonar to turn on." ”

As the power is turned on, the sonar array mounted on the hull of the ship begins to work, converting all kinds of underwater sounds into electrical signals and transmitting them into the headphones worn by the sonar soldiers.

But apart from the various undersea noises, the sonar array failed to capture anything useful.

"Captain, there's only undersea noise in the headphones, I can't hear them." After listening for a while, the sonar soldier reported, "The Germans may have gone into silence as well...... Should we turn on active sonar? ”

"Nope." Finch shook his head and refused, "The Germans are definitely searching for us with sonar right now, and we may not be able to spot them immediately with active sonar, but they will definitely be able to spot us as soon as possible." ”

"Then we ......"

"Let's spend it." Finch sat down on the captain's chair and crossed his legs and said, "Unless those Germans were fish all their lives, they will always have a time to bubble!" Let all the soldiers on the gun emplacements cheer up the spirit, and the Germans as hard as they come up! ”
