Operation Vijay in 1961 (Annexation of Goa)

Operation Vijay was a military operation launched by the Indian Army in 1961 to reclaim the Portuguese-held enclaves of Dadra and Nagar Haveli. The operation was launched on 19 July 1961 and concluded on 1 August 1961, with the region being annexed by India.

The operation was launched as a result of Portuguese refusal to negotiate the transfer of the enclaves to India. The Indian Army, under the command of Major General Chaudhuri, launched a two-pronged attack on the enclaves. The first prong was a frontal attack on the Portuguese fortifications, while the second was a flanking manoeuvre to encircle the Portuguese forces.

The operation was successful, with the Indian forces capturing the enclaves in just over a week. The Portuguese forces, who were outnumbered and outgunned, were unable to withstand the Indian attack and were forced to surrender.

The success of Operation Vijay was a major victory for India, as it demonstrated the capability of the Indian Army to successfully conduct operations against a well-armed and equipped adversary. The operation also served to bolster India's reputation as a regional power and helped to strengthen its position in the international arena.
