  5. Riordan explains the risks of a 100-man plan

    Marston questions why they cannot send 100 men to Fort Medford, but Riordan explains that such a move would leave Fort Shallan defenseless.

The Last Frontier Timeline Explained: Your Questions Answered

When does it happen, and why in that order? The questions people ask about the chronology of The Last Frontier (1955): time jumps, flashbacks, cause and effect between scenes and the correct order of events, each answered with spoilers.

Q1

Why does Jed forcibly kiss Corrina?

Jed kisses Corrina in a moment of longing and desperation as the imminent massacre looms. Having witnessed the strain between Corrina and her husband and feeling his own uncertain fate, Jed acts impulsively to express his attraction and possibly win her sympathy. Corrina rebuffs him, but the tense moment reveals Jed's willingness to take risks and shape outcomes beyond the battlefield.

Foreshadowing: Earlier, Jed had asked Corrina for whiskey and learned about her husband, establishing his interest in her.

  • jed cooper
  • corrina marston
  • kiss
  • romance
  • tension
Q2

Why does Colonel Marston take command from Captain Riordan?

Marston asserts his authority as the senior officer in the territory, arguing that he has the right to command since he holds a higher rank than Riordan. Despite Riordan's resistance, Marston uses his battlefield experience from Shiloh to justify his decisions and pushes for an aggressive offensive against Red Cloud rather than merely holding the fort.

Foreshadowing: The power struggle is foreshadowed when Marston questions why Riordan cannot send 100 men, establishing his belief in his own command authority.

  • colonel marston
  • captain riordan
  • command
  • authority
  • rank
Q3

What happens to Gus during the ambush?

Gus is shot and killed while scouting ahead of Marston's column. He signals a warning to fall back into the trees, but his advice is ignored by the cavalry. Jed finds him dying and receives his final instructions to take shelter and keep moving through the trees toward safety. Gus's death is a major loss for Jed and marks a turning point in the battle.

Foreshadowing: Jed had suspected the mission to Fort Medford was perilous, and when he discovers the remnants of Marston's party, the danger becomes clear.

  • gus death
  • killed
  • battle
  • ambush
  • scout
Q4

Why does Jed warn about the imminent massacre?

Jed had visited Red Cloud's camp and discovered the tribe was gathering a large alliance of tribes for a coordinated attack. After witnessing the war party's positioning and recognizing the danger to Marston's marching column, Jed returns to the fort drunk and bursts through the ranks shouting a warning. His intentions are to save the soldiers, though his drunken state and aggressive delivery lead to chaos.

Foreshadowing: Earlier, Jed reports to Riordan that Red Cloud is gathering a large alliance and warns that the fort could be overrun if the snowbound advance comes before winter.

  • jed warning
  • massacre
  • red cloud
  • attack
  • drunken
Q5

Why does Riordan aim his pistol at Jed but not fire?

Foreshadowing: Riordan had previously supported holding the fort rather than launching an offensive, suggesting he harbors doubts about Marston's leadership.

  • captain riordan
  • jed
  • hanged
  • punishment
  • command
Q6

Why does Jed lie about Colonel Marston being dead?

After Marston steps into a bear trap during scouting, Jed negotiates with the soldiers to keep Marston from pursuing Red Cloud. Marston refuses to stay behind, but Jed returns to the fort with Marston's horse alone. When Riordan and Dr. Clarke ask about Marston, Jed lies and says he is dead, possibly to prevent Marston from leading the dangerous mission or to protect his own position.

Foreshadowing: This lie occurs after Jed and Marston scout Red Cloud's camp together, where Marston's reckless behavior becomes evident.

  • jed
  • marston
  • lie
  • death
  • bear trap
Q7

Why does Fort Shallan survive the Indian attack?

Winter arrives just in time to halt Red Cloud's assault. The snow blankets the landscape and blunts further attacks, buying the fort a temporary reprieve. While the cavalry's charge fails and many soldiers die, the infantry successfully maneuvers through the trees and regroups. The harsh winter conditions ultimately protect the fort from annihilation.

Foreshadowing: Jed had warned that if Red Cloud's snowbound advance came before winter, the fort could be overrun, making the winter's arrival crucial.

  • fort shallan
  • survive
  • winter
  • snow
  • red cloud
Q8

Why is Jed promoted to sergeant?

Jed earns promotion to sergeant in recognition of his leadership during the battle. He spots Red Cloud's waiting war party, fires on an approaching scout to give warning, and directs the infantry to take shelter in the trees. Despite the cavalry's failure, Jed's actions under fire demonstrate his capability as a leader and earn him a measure of vindication for his earlier troubles at the fort.

Foreshadowing: Throughout the film, Jed consistently demonstrates survival skills and local knowledge that exceed those of the regular soldiers.

  • jed
  • promotion
  • sergeant
  • battle
  • leadership
Q9

Why does Marston want to attack Red Cloud instead of defending the fort?

Marston believes in taking the offensive rather than waiting to be attacked. He argues that if they do not strike Red Cloud first, they will lose Fort Shallan and push the defensive line back toward Fort Laramie. Citing his experience at Shiloh, Marston asserts that aggressive action is necessary, though his physician Dr. Clarke cautions that Marston is a doctor, not a military strategist.

Foreshadowing: Marston's arrival at Fort Shallan brings a sense that glory is scarce in this posting, motivating him to prove himself through offensive action.

  • marston
  • attack
  • red cloud
  • offensive
  • shiloh
Q10

Why does the cavalry charge fail during the ambush?

The cavalry ignores Gus's advice to use the cover of the trees for shelter. Instead of retreating or taking cover, they charge directly into the ambush and perish in the snow. Meanwhile, the infantry follows Jed's instructions to maneuver through the trees and successfully regroups under heavy fire. The cavalry's failure to follow proper tactical advice leads to their destruction.

Foreshadowing: Gus had warned about the danger and urged the troops to use the trees, but his counsel was disregarded.

  • cavalry
  • failure
  • ambush
  • charge
  • trees
Q11

Why does Red Cloud attack the forts?

Red Cloud and his tribe attack because they are defending their land from military encroachment. Earlier in the film, Red Cloud demands that Jed and his partners leave the territory or face death. The chief is gathering a large alliance of tribes for a coordinated offensive, intending to push back the military presence and protect their territory from further expansion.

Foreshadowing: The initial confrontation with Red Cloud establishes his hostile stance toward any military or settler presence in the region.

  • red cloud
  • attack
  • tribe
  • land
  • defense
Q12

Why is Mungo sent to Fort Laramie?

Riordan sends Mungo to Fort Laramie to obtain fresh orders and determine whether to hold the fort through winter or pursue other strategies. Mungo returns with orders that deny Riordan's request, effectively leaving Marston in command. This crucial mission determines the chain of command and the fort's ultimate fate during the winter period.

Foreshadowing: Earlier, Riordan had explained that his orders were to hold the fort, making formal orders from higher authority critical to the leadership dispute.

  • mungo
  • fort laramie
  • orders
  • command
