In December 1961, the small garrisons of the Portuguese Army in the Portuguese India had to face an invasion from overwhelmingly stronger Indian ground, air and naval forces. After brief resistances, each of the isolated Portuguese garrisons of Goa, of Daman, of Diu and of the Angidiva island collapse and surrender. In Africa, the Portuguese Army would be deeply engaged in military counterinsurgency campaigns against separatists forces, that became collectively known as the "Colonial War" or the "Overseas War". These campaigns are fought in three different theatres of operations, separated by thousands of kilometers from each other and from the European Portugal: Angola (1961-1974), Portuguese Guinea (1963-1974) and Mozambique (1964-1974). Despite having almost no external support and facing enemies strongly supported by the Warsaw Pact and even by some Western European countries and despite having to fight in three distant theaters at the same time, the small Portuguese Armed Forces were able to resist in campaign for 13 years. The counterinsurgency campaigns in Africa had various degrees of success, with an almost victory of the Portuguese Armed Forces in Angola, a stalemate in Mozambique and a disadvantageous almost conventional warfare situation in Portuguese Guinea. This war ended after the Carnation Revolution military coup of 25 April 1974 in Lisbon and the subsequently independence of the Portuguese African overseas provinces.
