[2] [3]: 162 Nzula was so impressed with Wolton that he travelled to Johannesburg to pick up books and literature at the party's headquarters.
[2] He was described by Edwin Thabo Mofutsanyana (also served as the general-secretary of the CPSA), as an excellent propagandist and agitator during public speaking.
Nzula was also a member of the ANC and he supported Josiah Tshangana Gumede to make the organisation more radical in their approach against discriminatory laws.
That year (1930), Nzula was the chairman at the All-in-conference held at the Trades Hall in Johannesburg to launch a campaign to fight repressive legislations introduced in parliament by the then Justice Minister Oswald Pirow.
[6] Nzula organised a mass meeting for unemployed Africans and he led them on a massive demonstration on 1 May 1931, which merged into one huge procession with white workers.
[7] Wolton nominated Nzula and Moses Kotane, due to their grasp of Marxism and leadership potential, to travel to the Soviet Union for further schooling and education.
[9] He is described by the SACP as: strong and fearless, his influence grew rapidly… He was emphatic that the leadership of the party must pass primarily into the hands of Africans.
[11] It was decided that he could not return to South Africa, for fear that his views would contaminate the minds of the members in that country with Trotskyite ideas.
[11] Nzula died on 17 January 1934 as a result of inflammation of lungs – lobar pneumonia – which he contracted having overdosed on alcohol and fallen asleep outdoor in sub-zero temperatures.
