In February 1974, Caetano decided to remove General António de Spínola from the command of Portuguese forces in Guinea in the face of Spínola's increasing disagreement with the promotion of military officers and the direction of Portuguese colonial policy. This occurred shortly after the publication of Spínola's book, "Portugal and the Future", which expressed his political and military views of the Portuguese Colonial War. Several military officers who opposed the war formed the MFA to overthrow the government in a military coup. The MFA was headed by Vítor Alves, Otelo Saraiva de Carvalho and Vasco Lourenço, and was joined later by Salgueiro Maia. The movement was aided by other Portuguese army officers who supported Spínola and democratic civil and military reform. It is speculated that Francisco da Costa Gomes actually led the revolution.
