Up to 1959, Cabral had been over-cautious and avoided the fate of many of his comrades, such Agostinho Neto or Mário Pinto de Andrade, who either were in jail or exiled on account of their subversive political activities. However, after his last trip to Angola and Guinea, in 1959, where he had witnessed the crackdown of nationalist organizations, he could no longer maintain his duplicity. He then comes out as a nationalist in a grand way. It was in London, in early 1960s, that he publishes the first political pamphlet under his name, Facts about Portugal’s African colonies,” and he gives a press conference to denounce Portuguese colonialism. From there, Cabral settles in West Africa, particularly in Guinea-Bissau, where he started the work of preparing to launch the anti-colonial war against the Portuguese.
