On April 2, 1982, a military operation began that changed Argentine history: the landing of troops on the Malvinas Islands. This action, known as Operation Rosario, allowed Argentina to regain control of the archipelago in a few hours and initiated the subsequent war with the United Kingdom, which lasted for 74 days. The direct commander of the Landing Force was Rear Admiral Carlos Alberto Büsser, who coordinated the joint deployment of marines, amphibious commandos, and units of the Argentine Army. This deployment allowed for the rapid consolidation of control over the capital of the archipelago. Every year, this date is remembered in Argentina as the Day of the Veteran and of the Fallen in the Malvinas War, in homage to those who participated in the conflict and those who lost their lives in the defense of national sovereignty. Shortly after, British Governor Rex Hunt negotiated his surrender around 9:30 AM. Within hours, the capital of the archipelago was under Argentine control through a coordinated and swiftly executed amphibious operation. The initial objective of the operation and the beginning of the war Operation Rosario aimed to regain control of the islands and open a subsequent diplomatic negotiation instance with the United Kingdom. Amphibious commandos landed at Green Beach and in the vicinity of the British governor's residence, in what is now Puerto Argentino. Argentine soldiers raised the national flag in Puerto Argentino after taking the Malvinas Islands. The mission was kept under strict secrecy until the last moment, even for most of the embarked personnel. Hours before the start of the operation, Büsser gave an address from the ARA Cabo San Antonio, making it clear the objective: to land on the islands, expel the British authorities, and respect the civilian population of the territory. How the landing in Puerto Argentino took place during the early morning The operation began during the night of April 1st. However, the British response led to the Falklands War, which lasted for 74 days. The April 2nd operation was a precision action carried out in a few hours, with the joint participation of amphibious forces, special commandos, and air support. At 6:15 AM on April 2, armored amphibious vehicles secured the local airport, allowing C-130 Hercules aircraft to land with reinforcements and equipment. After brief clashes around the Governor's House, Captain Pedro Edgardo Giachino died, considered the first Argentine casualty of the operation.
