The Frogmen (1951) Timeline Explained – Every Event in Order

Lawrence was perceived as a coward because during the reconnaissance mission, when two frogmen including Chief Flannigan were still in the water after the diversion boat was hit by artillery, he ordered a rescue boat rather than continuing with the mission to secure the beach information. The men saw this as prioritizing safety over completing the objective, especially since he had also assigned Lt. Klinger to the more dangerous beach. This decision, combined with his strict disciplinary approach, made the unit believe he was unwilling to risk his own men or himself.

Foreshadowing: Earlier, Lawrence's by-the-book discipline and his assignment of Klinger to the dangerous beach already planted seeds of distrust among the men.

Lawrence assigned Lt. Klinger to the dangerous beach as a diversion to draw enemy fire away from the main landing site. The assignment was tactical, Klinger's group was meant to create a distraction while the main force conducted the actual reconnaissance. However, the mission went wrong when the diversionary pick-up boat was directly hit by artillery, killing Klinger and most of his men, which deepened the unit's suspicion that Lawrence had sent Klinger to a death trap.

Foreshadowing: Lawrence's earlier refusal to show leniency at captain's mast foreshadows his willingness to make tough, unpopular decisions.

Lawrence kept his coral poisoning secret because he was concerned that revealing his illness would further damage his already poor standing with the unit. He feared the men would see it as another excuse to avoid dangerous duty, reinforcing their view of him as a coward. Instead, he put Flannigan in charge of the mission and stayed behind, which only intensified the men's contempt for his perceived cowardice.

Foreshadowing: His earlier decision to prioritize the rescue over the mission objective had already created the perception that he avoided risk.

Creighton sneaked onto the beach with Flannigan to place a sign that would "welcome" the approaching U.S. Marines, a prank intended to boost morale. However, Japanese sentries spotted Creighton and shot him. Flannigan managed to tow him back to the pick-up boat, but Creighton was left with bullets in his spine and had to be placed in traction aboard the ship.

Foreshadowing: The men's earlier resentment toward Lawrence set the stage for this reckless prank as an act of defiance.

Lawrence volunteered to disarm the torpedo because it had lodged in the sick bay right next to Creighton's bed, posing an immediate danger to the wounded crew and the entire ship. Despite the risky nature of the task, he took responsibility to protect his men. With Flannigan's help, he successfully disarmed the torpedo, which began shifting the crew's perception of him as someone willing to face danger alongside them.

Foreshadowing: This act directly followed the men's request for transfers, showing Lawrence's commitment to the unit despite their hostility.

Flannigan and several other frogmen requested transfers because they genuinely believed Lawrence was a coward who put his own safety above the mission and his men. After the rescue boat controversy and seeing Lawrence stay behind during the morning mission while claiming illness, they lost confidence in his leadership. Their request was also fueled by anger after Lawrence rebuked Flannigan for the prank that got Creighton shot, which they felt was unfair given the circumstances.

Foreshadowing: The cumulative effect of Lawrence's perceived cowardice and strict discipline drove the men to seek transfer.

Lawrence earned the men's respect through his actions during the final mission to destroy the Japanese submarine pen. When the mission was discovered and Japanese sentries engaged the team, Lawrence led the assault and was stabbed in hand-to-hand combat with a Japanese diver. Despite being wounded, he ordered Flannigan to leave him behind, but Flannigan towed him to safety. This willingness to risk his life for the mission, combined with his earlier act of disarming the torpedo, finally convinced the men that he was a brave and committed leader.

Foreshadowing: His earlier volunteer act to disarm the torpedo was the first step toward changing their opinion.

Lt. Klinger was leading the diversionary group assigned to the more dangerous beach when their pick-up boat received a direct hit from Japanese artillery during extraction. The attack killed Klinger and most of his men. This tragedy occurred right after Lawrence himself had been cut on coral and was already compromised, making the situation even more chaotic and dangerous.

Foreshadowing: Lawrence's decision to split the platoon and assign Klinger to the risky beach set this disaster in motion.

Lawrence insisted on holding his own mast and disciplining the entire team despite the ship's captain offering to go easy on them. He believed that rules must apply equally to everyone, especially before a dangerous mission where discipline could mean the difference between life and death. While this approach won him no favors with the men already grieving their fallen leader Cassidy, it established his authority as their commander and set a strict tone for the unit.

Foreshadowing: This strict discipline immediately after taking command showed Lawrence's leadership philosophy, which clashed with the men's loyalty to their previous leader.

During the final mission to blow up the Japanese submarine pen, the frogmen were discovered when one of the men accidentally tripped a signal wire. Japanese sentries began shooting at the team as they tried to plant the charges. Lawrence engaged in hand-to-hand combat with a Japanese diver and was stabbed during the struggle. Despite his injury, he ordered Flannigan to leave him behind, but Flannigan refused and towed him to safety, ensuring the mission was completed successfully.

Foreshadowing: The earlier rescue situation where Lawrence ordered Flannigan to be saved was reversed here, with Flannigan now saving Lawrence.

After the successful submarine pen mission, the men asked Lawrence to sign the portrait they had drawn of their fallen leader Lt. Cmdr. Jack Cassidy, which they intended to present to Cassidy's widow. This gesture marked the complete transformation of the unit's relationship with Lawrence, instead of viewing him as a replacement for their beloved former commander, they now accepted him as a worthy leader in his own right. The signing symbolized their reconciliation and respect.

Foreshadowing: The men's initial hostility toward Lawrence was directly tied to their loyalty to Cassidy, making this moment a full circle resolution.
