12.12: The Day (2023) Timeline Explained – Every Event in Order

General Jung Sang-ho appointed Lee Tae-shin as commander of the Capital Defense Command specifically to counterbalance Chun Doo-gwang's growing influence. Jung recognized the danger of Chun's ambitions to seize military and political control, so he chose Lee, a principled, politically neutral officer known for opposing military interference in politics, to block Chun's power grab. Lee initially resisted the appointment due to his reluctance to get involved in political disputes, but accepted out of duty to his country.

Foreshadowing: This appointment was Jung's attempt to create a checks-and-balances system within the military hierarchy, though it ultimately proved insufficient to stop Chun's conspiracy.

Chun Doo-gwang executed the coup through careful preparation and manipulation. He assembled loyal members of the secretive Hanahoe faction, including General Noh Tae-gun, and devised a plan to arrest General Jung Sang-ho on fabricated charges. On December 12, Chun's forces deceived government officials by mobilizing units under the Hanahoe's influence, then forcibly abducted Jung from his residence despite fierce resistance and a shootout that injured Jung's aides. By controlling the narrative and using military force before authorities could react, Chun successfully seized control of the situation.

Foreshadowing: Chun had been consolidating power since the assassination investigation, systematically sidelining officials and misappropriating state funds to build his faction's resources.

Defense Minister Oh Guk-sang, who had been in hiding during the crisis, unexpectedly arrived at the standoff and ordered Lee Tae-shin to dismiss his forces. This intervention effectively ended Lee's counteroffensive and shifted control back to Chun's loyalists. The exact motivations behind Oh's decision are not fully detailed in the film, but his order halted the only serious military resistance to the coup, allowing Chun to regain dominance. This pivotal moment represents the collapse of legitimate authority and the triumph of Chun's conspiracy.

Foreshadowing: Oh Guk-sang's mysterious disappearance and sudden reappearance suggests he may have been coerced or aligned with Chun's faction all along.

The Hanahoe faction was a secretive military group composed of officers who supported Chun Doo-gwang's ambitions. This faction played a critical role in executing the December 12 coup, providing Chun with loyal troops and logistical support needed to abduct General Jung and seize control of key military installations. The members believed in Chun's vision of military leadership and were willing to participate in the conspiracy to overthrow the existing command structure. Their coordinated action was essential to the coup's initial success.

General Jung Sang-ho was abducted from his residence on December 12 during the coup operation. Despite fierce resistance from his aides during the abduction, Chun's forces successfully captured him. Following his arrest on fabricated charges, Jung became a prisoner of the Hanahoe faction. His removal from command eliminated the primary obstacle to Chun's power grab, as Jung was one of the few senior officers actively opposing Chun's ambitions. The film implies Jung was detained and unable to prevent the consolidation of Chun's control.

Foreshadowing: Jung's warning to Chun about avoiding military interference in politics had already signaled the deepening conflict between them.

Lee Tae-shin issued the threat to shell the rebel-held 30th Security Group as a last-ditch effort to prevent Chun's coup from succeeding. After discovering the coup plot, Lee ordered loyal military units to block key bridges and entry points into Seoul. When these measures proved insufficient to stop Chun's forces, Lee escalated his response by threatening heavy artillery action against the 30th Security Group unless they surrendered. This represented Lee's determination to use overwhelming force to restore constitutional order and prevent the military takeover.

After Lee Tae-shin's forces were disbanded following Defense Minister Oh Guk-sang's order, Lee refused to accept defeat quietly. He approached Chun Doo-gwang alone in what appears to have been a direct confrontation or attempt to negotiate. However, this act of defiance led to Lee's immediate arrest. Chun viewed Lee as a significant threat to his coup and was not willing to allow a high-profile opponent to remain free. Lee's arrest marked the end of organized resistance to Chun's takeover, and his loyalists subsequently faced torture and detention.

After successfully consolidating power through the December 12 coup and arresting key opponents like Lee Tae-shin, Chun Doo-gwang secured retroactive approval from the president for his actions. This formal endorsement transformed the coup from an illegal military operation into an officially sanctioned intervention. By obtaining this retroactive approval, Chun legitimized his seizure of power and paved the way for his authoritarian rule. This political maneuvering completed Chun's transformation from coup plotter to de facto leader of South Korea.

Prime Minister Choi Han-kyu declared martial law across most of South Korea immediately after announcing President Park Chung-hee's death on October 26, 1979. The declaration was ostensibly aimed at maintaining order during the political crisis created by the assassination. However, this move also represented an attempt by military and government leaders to fill the power vacuum and establish control during the uncertain transition period. Only Jeju Island was exempted from martial law. The declaration set the stage for the subsequent power struggle between military factions.

Foreshadowing: The martial law declaration gave military leaders unprecedented authority, which Chun Doo-gwang would later exploit for his own purposes.

The 30th Security Group was a military unit that was under rebel control during the December 12 coup attempt. Lee Tae-shin's threat to shell this unit represented his most aggressive effort to stop the coup by military force. The unit's significance lies in its strategic location within Seoul and its control by Chun's loyalists during the crisis. By threatening to use artillery against a fellow military unit, Lee demonstrated the extreme gravity of the situation and the willingness of legitimate forces to use devastating force to prevent the coup's success.

Chun Doo-gwang falsely accused Lee Tae-shin of complicity in President Park's assassination as part of his strategy to eliminate a potential rival. After Jung Sang-ho appointed Lee as Capital Defense Commander to counterbalance his power, Chun recognized Lee as a significant obstacle to his coup plans. By fabricating evidence linking Lee to the assassination, Chun sought to discredit him, remove him from command, and pave the way for his own takeover. This baseless accusation demonstrates Chun's willingness to use deception and manipulation to achieve his political ambitions.

The December 12, 1979 coup resulted in Chun Doo-gwang successfully seizing control of South Korea's government. Despite resistance from Lee Tae-shin's loyal forces, the intervention of Defense Minister Oh Guk-sang and the subsequent arrest of Lee eliminated organized opposition. Chun then secured retroactive presidential approval for his actions, legitimizing his takeover. The coup marked the beginning of Chun's authoritarian rule, which would last for nearly a decade. The film portrays this as a grim turning point where democracy was overthrown by military conspiracy, with loyalists facing torture and the nation entering a dark period of dictatorship.
