Guinea History Portuguese Invasion, 1970

Operation Green Sea (Portuguese: Operação Mar Verde) was an amphibious attack on Conakry, the capital of Guinea, by between 350 and 420 Portuguese soldiers and Portuguese-led Guinean fighters in November 1970. The goals of the operation included the overthrow of Ahmed Sékou Touré's government, capture of the leader of the African Party for the Independence of Guinea and Cape Verde (PAIGC), Amílcar Cabral, destruction of the naval and air assets of the PAIGC and its Guinean supporters, and the rescue of Portuguese POWs held in Conakry. The attackers withdrew after rescuing the POWs and destroying some PAIGC ships and Guinean Air Force infrastructure, but failed to capture Amílcar Cabral, the leader of PAIGC guerrillas (who was in Europe at the time), or to topple the regime of Guinean leader Ahmed Sékou Touré.
