The pdf link below is chapter fifteen from volume one of Ernest Tate’s memoir, “Revolutionary Activism in the 1950s and 1960s”, published by Resistance Books, London. In this chapter, using archival sources, he describes in detail how a small group of Canadian revolutionary socialists in the Socialist Educational League, S.E.L., later to become the League for Socialist Action, L.S.A., of which he was a leader, organized in 1960 to defend the early Cuban Revolution against a right-wing propaganda offensive inspired by American imperialism, designed to quarantine it from the Canadian people. Their campaign in defense of Cuba, he writes, was one of the most successful of its kind in the English-speaking world.
