In short: Known as Operation Vijay, India’s military annexation of Goa, Daman, and Diu concluded centuries of Portuguese colonial presence. While India celebrated the event as a long-awaited liberation of its territory, Portugal viewed the move as an act of aggression against its sovereign soil, sparking a complex international diplomatic fallout.

The conflict was the culmination of years of escalating tensions. Following India's independence in 1947, the Portuguese Estado Novo regime, a dictatorship committed to maintaining its overseas empire, refused to negotiate the status of its Indian exclaves. Prime Minister António de Oliveira Salazar insisted these territories were not colonies but integral parts of metropolitan Portugal. By 1954, India had instituted economic sanctions and visa restrictions, and supported armed groups like the Azad Gomantak Dal to destabilize Portuguese control.

By 1961, the military disparity was stark. Despite attempts to reinforce the garrison, Portuguese forces in India numbered only about 3,300 soldiers, while India mobilized the 17th Infantry Division and the 50th Parachute Brigade. Portuguese military leaders, including General Júlio Botelho Moniz, had warned Salazar that a sustained campaign against decolonization was a 'suicide mission.' Nevertheless, Salazar ordered Governor General Manuel António Vassalo e Silva to fight to the last man, forbidding any surrender.

The operation began in December 1961, involving synchronized air, sea, and land strikes. Despite Salazar’s orders, Vassalo e Silva surrendered after just 36 hours of fighting to prevent unnecessary loss of life. The brief engagement resulted in 22 Indian and 30 Portuguese deaths. Following the surrender, the territory was placed under military administration before transitioning to a civilian government in 1962. The event remains a point of historical contrast: India views it as the reclamation of historically Indian land, while Portugal’s perspective was defined by the loss of a centuries-old imperial outpost.

The annexation also highlighted the limitations of colonial defense in the post-war era. Portugal’s reliance on the 'Plano Sentinela'—a defensive strategy based on delaying tactics—proved unachievable due to a lack of equipment and communication infrastructure. Ultimately, the rapid collapse of Portuguese authority in India signaled the end of an era, as other global powers had already largely acceded to international calls for decolonization.
