The U48 submarine cocked its tail and plunged headlong into the deep sea.

"Heading 30!" Schultz motioned to the non-commissioned officer standing next to him to put away the periscope and, at the beginning of the submarine, gave the order to make a right turn. The echo rangefinder makes a high-pitched, rapid sound, indicating that the adversary is speeding in their direction.

"Yes, turn left 30, sir!" The helmsman's answer seemed to be masked by the alarm from the sonar.

A destroyer roared from their left like a train overhead, booming and booming.

"Watch out for depth charges!" Schultz shouted.

U48 was shaking violently, still diving rapidly, as if it was about to fall into the abyss. With an earth-shattering sound of power, the entire submarine shook violently as if it had been hit by a heavy hammer.
