Hiw did the Indian government gain …

 After the end of British India in 1947 and the emergence of the Indian Union, the Indian government demanded the Portuguese hand over their colonies to the Union. Refusal would lead to a conflict. On 24 July 1954 an organisation called "The United Front of Goans" took control of the enclave of Dadra.

French India was a French colony comprising geographically separate enclaves on the Indian subcontinent. The possessions were originally acquired by the French East India Company beginning in the second half of the 17th century, and were de facto incorporated into the Republic of India in 1950 and 1954. The French establishments included Pondichéry, Karikal and Yanaon on the Coromandel Coast, Mahé on the Malabar Coast and Chandernagor in Bengal. French India also included several logesin other towns, but after 1816, the loges had little commercial importance and the towns to which they were attached came under British administration.
