In Angola all the Portuguese forces retreat in the province of Cabinda, for his economically importance of the oil reserve, so the Portughese Army militarized the province and asked at Angola if they can signed a treaty of peace, and so it will be with the treaty of Luanda, the treaty say about the official end of the war between Portugal and Angola and the concession of Cabinda forever, the other colonies who are Sao Tome and Principe, Guinea-Bissau and Cape Verde decide with a referendum if become independent or remain in Portugal, surprisingly the 90% of the population of Guinea-Brissau decide to become independence, the same things happened to Sao Tome, but not at Cape Verde, who decide with a marginal victory of the 51% of stay with Portugal and become autonomous region, and he have say currently Angola and Mozambique are in a civil war, and he have he would be say at the general-governor of Cabinda about South Africa and the wish of the South-African government of restore relations with Portugal.
