The Atlantic Trial

A British destroyer attacks U-96, followed by weeks of punishing North Atlantic storms. The crew's morale falls before a convoy sighting restores their readiness for combat.

Key Events

• Destroyer Depth Charge Attack — A British destroyer attacks U-96 after it is spotted, but the submarine escapes with light damage. Characters: Lieutenant Werner, Chief Engineer, Kriechbaum Location: North Atlantic

• Four Torpedoes Fired — U-96 launches four torpedoes and sinks two ships in the Allied convoy. Characters: Lieutenant Werner, Chief Engineer, Kriechbaum Location: North Atlantic convoy route

Convoy and Moral Ruin

U-96 sinks two ships but is driven below test depth by the convoy escorts. After surviving the attack, the crew watches sailors abandon a burning tanker they cannot accommodate.

Key Events

• Four Torpedoes Fired — U-96 launches four torpedoes and sinks two ships in the Allied convoy. Characters: Lieutenant Werner, Chief Engineer, Kriechbaum Location: North Atlantic convoy route
• Below Test Depth — Escorting warships force U-96 below its rated test depth under sustained depth-charge attack. Characters: Lieutenant Werner, Chief Engineer, Kriechbaum Location: Deep North Atlantic

• Burning Tanker Reattacked — The crew torpedoes a still-burning tanker again and sees sailors jump into the sea. Characters: Lieutenant Werner, Chief Engineer Location: North Atlantic

The Gibraltar Gamble

Orders redirect the damaged crew toward La Spezia and the dangerous Strait of Gibraltar. A secret Vigo resupply cannot change the fact that their requests to leave are denied.

Buried Beneath the Sea

A British fighter damages U-96 and wounds Kriechbaum, forcing an emergency descent. The submarine lands on a deep sea shelf, where repairs and dwindling oxygen determine whether the crew survives.

Key Events

• Emergency Descent — Shelling forces U-96 underwater, where it continues sinking toward crush depth. Characters: Lieutenant Werner, Chief Engineer, Kriechbaum Location: Waters near Gibraltar
• Sea Shelf Landing — The submarine lands on a sea shelf at 280 metres, narrowly avoiding destruction at crush depth. Characters: Lieutenant Werner, Chief Engineer Location: Sea shelf at 280 metres
• Sixteen-Hour Repairs — The crew repairs the damaged submarine while its oxygen supply steadily runs out. Characters: Lieutenant Werner, Chief Engineer Location: Seabed near Gibraltar
• Ballast Tanks Blown — After more than sixteen hours, U-96 blows its ballast tanks and reaches the surface. Characters: Lieutenant Werner, Chief Engineer Location: Waters near Gibraltar
