Torpedo Run (1958) Timeline Explained – Every Event in Order

Doyle faces an impossible choice: the convoy is too well-guarded to attack the carrier directly, and the transport is the only viable target. He calculates a shot that he hopes will hit the transport while missing the carrier. He chooses duty over personal survival, believing the mission's success justifies the risk, even though it means potentially killing his own family.

Foreshadowing: Early in the chase, Sloan explicitly pleads to handle the torpedo run so Doyle won't have to live with the guilt of his family's death.

The Japanese deliberately refuse to rescue the survivors. They use the distress situation as bait to lure the American submarine to the surface, hoping to expose it to aerial attack. Doyle sees women and children clinging to wreckage through his periscope but cannot risk his crew by surfacing.

Foreshadowing: The Japanese escort's strategic positioning around the convoy hints at their willingness to sacrifice the transport for a chance to destroy the submarine.

Sloan refuses the promotion because he believes Doyle is still mentally fit to command and deserves to finish the mission. Sloan also feels guilty about the civilian transport disaster and wants to stay as Doyle's second-in-command to share the burden. Setton only agrees to give Greyfish one more chance on condition Sloan takes the promotion if Doyle fails.

Foreshadowing: Earlier, Sloan begged Doyle to let him handle the attack, showing his loyalty and desire to protect Doyle from moral injury.

Doyle suspects he's been demoted to a quiet patrol as punishment, but the assignment is actually strategically sound. Unknown to Doyle at the time, the Shinaru is heading toward Japanese-occupied Kiska Harbor in the Aleutians. The 'punishment' turns out to be exactly where the target is headed.

Foreshadowing: The mysterious transfer to Alaska is presented as betrayal, but the timeline structure hints that Setton may have intelligence about the Shinaru's movements.

Doyle reveals he knew about the offer all along. While the film doesn't specify how, he likely overheard conversations or noticed the interaction between Sloan and Admiral Setton. His open acknowledgment of this knowledge during the Alaska assignment confrontation shows he has been processing the information quietly and uses it to fuel his anger about the perceived betrayal.

Foreshadowing: Sloan's meeting with Setton happens off-screen but Doyle's knowing reaction suggests he was aware of the promotion discussion before the public revelation.

Momsen lungs are an emergency escape device used by submarines. Named after Lieutenant Commander Charles Momsen, they allow crew members to breathe fresh air from a compressed tank while escaping a flooded submarine. When depth charges force Greyfish to the ocean floor and the vessel is doomed, the crew uses these devices to make their way to the surface rather than being trapped inside the sinking hull.

Foreshadowing: The submarine's mounting damage from depth charges builds toward a final catastrophic failure that requires emergency escape equipment.

After the Greyfish is destroyed and the crew escapes using Momsen lungs, they are rescued by another American submarine, the Bluefin. Doyle asks the Bluefin's captain to confirm whether the Shinaru sank. The captain looks through the periscope, shows Doyle and Sloan the view, then announces over the intercom that the carrier has gone down.

Foreshadowing: The film's structure builds toward this confirmation scene as the climactic payoff after the destructive final attack.

Doyle refuses to delegate the decision because he views the mission as his responsibility as commanding officer. He believes stepping back would be cowardice and a dereliction of duty. Additionally, he may feel he deserves the moral burden if his family dies, choosing not to act would haunt him more than living with the consequences of his own orders.

Foreshadowing: This mirrors the opening directive from ComSubPac assigning the mission directly to Doyle, establishing his personal stake from the start.

Doyle pursues the Shinaru into Tokyo Bay but the attack fails. The exact reason isn't detailed in the summary, but Tokyo Bay would have had heavy defenses, strong currents, and limited maneuvering room. The submarine endures relentless depth charge bombardment and is forced to retreat, returning to Pearl Harbor damaged but intact.

Foreshadowing: The failed Tokyo Bay attack establishes that sinking the carrier will require multiple attempts and greater risk.

Doyle is faced with a brutal calculation: surfacing to rescue survivors would expose the submarine to Japanese aircraft and warships. The Japanese are already using the survivors as bait to draw out the submarine. To protect his crew's lives, Doyle makes the agonizing decision to submerge and leave the prisoners, including his own wife and child, to their fate.

Foreshadowing: The Japanese refusal to rescue their own people is visible through the periscope, making Doyle's decision even more tragic.

After the torpedo hits the transport, the Greyfish remains submerged to avoid detection. The crew witnesses through the periscope the Japanese ignoring the survivors and using them as bait. Unable to help without sacrificing his crew, Doyle orders the submarine to shadow the Shinaru into Tokyo Bay for another attack attempt.

Foreshadowing: The immediate aftermath shows the moral weight already affecting Doyle before the Tokyo Bay engagement even begins.

Doyle's grief transforms into determined vengeance. Having already paid the ultimate personal price, he becomes obsessed with completing the mission and sinking the Shinaru, the same carrier that led the Pearl Harbor attack. His drive becomes both personal retribution and professional duty, pushing the crew through the failed Tokyo Bay attack and ultimately to the final successful strike at Kiska Harbor.

Foreshadowing: The transition from Tokyo Bay failure to the Alaska mission shows Doyle's resolve hardening rather than breaking.
