Battle of Jutland, Showdown

Not long after the destroyer Cossack turned on the passive sonar, the submarine U47 at a depth of 50 meters also turned on the passive sonar.

"Sir! The sound of the propeller!" As soon as the sonar soldier turned on the passive sonar, he heard a distinct sound of the propeller.

"Location distance!" Prien calmly said.

"5.6 kilometers due west!"

"Sail west, slow down to a quarter! The whole boat is in second-level silence!"

"Understood, heading due west, slow down to a quarter!" The pilot repeated the command, and then stopped making any sound.

Not only him, but the entire crew of the boat stopped talking, and the only thing that made a sound was the commander's occasional low command, and only the low working sound of some machines.

The destroyer Cossack.

After U47 began to perform a second-level silence, the sonars on the Cossack lost track of U47.

"Sir, I lost track of the target." The sonar soldier said to the captain in frustration.

"It's okay." The captain comforted, "Where is their last position?"

"It's 5.6 kilometers due east of us."

After listening to the sonar soldier's words, the captain thought for a moment, and said: "No matter them, you continue to listen carefully, we go to the place where they disappeared, most of them are in a silent state, and they can't run very far in a silent state! "

"clear."

More than ten minutes later, the Cossacks arrived at the place where U47 was last detected.

After comparing the chart to determine his arrival position, the pilot reported to the captain, "Sir, we have arrived at the place."

The captain nodded when he heard the words, and then ordered: "Turn off the engine and create a quieter environment for our sonar soldiers!"

"Understood, the engine is off!"

With the pilot's operation, the Cossack's hull shook off all the power units, and then began to slide, and everyone in the bridge turned their attention to the sonar soldiers.

And the sonar soldiers lived up to expectations, once again successfully capturing the tiny sound of U47.

"I found him, sir!" The sonar soldier shouted excitedly to the captain after hearing the movement of U47.

"Location!"

"Due west 1.3 kilometers!"

"Smart guy, ran behind us?" The captain smiled, "Unfortunately we found you! Reverse at full speed and fire two salvos of depth charges at the stern!"

"Understood! Reversing at full speed." The driver restarted the engine, and the Cossack's chimney spewed smoke again, and the battleship fell from fast to slow toward the position of U47.

U47 submarine command room.

"Sir, the enemy ship is coming towards us! Due east 1.3 kilometers, 1.2 kilometers, 1.1 kilometers..." The sonar soldier broke the silence and said to Prien in horror, "Sir, we have been discovered!"

"Stabilize the soldier, hold on!" Although he was discovered, Prien remained calm as always.

But the situation did not get better because of Prien's calmness, on the contrary, it became more serious.

"Twice falling into the water! Sir, they released depth charges!"

"Distance!" Prien asked calmly.

"600 meters away!"

"600 meters away? No skills!" Priyan mocked, "Let the British see how good we are! Prepare the stern torpedo, set a depth of 2 meters, and launch it!"

"Understood, the stern torpedo has a depth of 2 meters, launch!" The messenger repeated Prien's order, and then passed the order to the stern torpedo compartment.

"Bang!" With a muffled sound, a 610mm torpedo was pushed out of the torpedo tube by compressed air, and while it was rapidly rising from 50 meters to 2 meters, it was pushed by the propeller and galloped towards the Cossack.

"The torpedo has been launched!"

"Very good, turn off the engine, the whole boat will enter the third-level silence!" Prien nodded and ordered while taking off his shoes.

After everyone got the order to enter the third-level silence, they took off their shoes one after another to prevent making noise when walking. Some people on non-combat posts even went straight back to the sailor quarters and tied themselves to beds.

Meanwhile, on the destroyer Cossack.

"Bubble sound! Propeller sound!" The sonar soldier heard the sound of U47 launching a torpedo, and shouted in horror, "The enemy submarine fired a torpedo at us!"

"Right full rudder! Emergency evasion!" The captain responded immediately, then ran to the port window and stared at the sea.

With the execution of the evasive action, the Cossack began to turn sharply to the right, and at the same time the hull tilted to the left due to inertia, which made many unprepared people fall upside down.

More than 20 seconds later, a snow-white torpedo trail flew past the Cossack's original position. If it wasn't for the early discovery by the sonar soldiers, the destroyer with a full-load displacement of only 2,420 tons would have been sent to the sky by this powerful 610mm torpedo at this time.

"God bless!" Looking at the wake, the crew wiped the cold sweat on their heads and said happily.

"Well done, man!" The captain rubbed the sonar soldier's head and praised, "You saved the lives of a boat!"

"It's nothing, sir! This is what I should do." The sonar soldier scratched his head honestly and smiled.

"Haha, humble boy." The captain laughed twice after hearing the sonar soldier's words, and said, "It's time for us to look for the German who littered the garbage, my good boy, where is he now?"

The sonar soldier listened to the captain's order, lowered his head and began to listen carefully.

After a long time, the sonar soldier raised his head helplessly and said to the captain, "Sir! Sorry, I can't find him again."

"I can't find it again?" The captain was stunned, "Did they turn off the engine?"

"Sir, what should we do?" Everyone asked, looking at the backbone of the warship.

"Turn on the active sonar!" The captain gritted his teeth and said, "Whether you can kill them depends on the two minutes that the active sonar has been activated!"

"Understood, active sonar is enabled!" The sonar soldier repeated the order, and then turned on the active sonar.

With the activation of active sonar, invisible sound waves emanated from the active sonar array of the Cossack and spread to the surrounding seawater.

And part of the sound waves that spread out hit the U47 and reflected back, and passed to the sonar soldier's earphones.

"The target was captured, 1,100 meters to the southwest, and the water depth is 50!" The sonar soldier recaptured U47 in the third-level silence and shouted excitedly.

"Prepare anti-submarine torpedoes! Set the depth to 50, set the distance to 1100, head southwest, and fire two salvos!"

"Understood, anti-submarine torpedo, heading southwest, two salvos!"

Following the captain's order, the two torpedoes were pushed into the water successively, sank to a depth of 50 meters, and then shot at U47.

"Captain! The enemy ship turned on the active sonar, and we were discovered!" The sonar soldier on U47 changed his face when he heard the Cossack destroyer turned on the active sonar.

But the sound that followed almost made him fall to the ground: "There are two propellers approaching from the northeast! The speed is 60 knots, and it is expected to collide in 35 seconds!"
