When the African National Congress decided to launch armed struggle in 1961, Comrade Khumalo was among the first to volunteer to join the revolutionary armed wing of the African National Congress - Umkhonto We Sizwe (Spear of the Nation) He will be remembered by many members of the fraternal liberation movements as a tireless functionary of the external mission of the ANC, both as deputy Chief Representative in the Dar-Es-Salaam office of the African National Congress.

When the Government of the Republic of Zambia gave the National Liberation Movements the opportunity to beam revolutionary programmes to their respective countries in Southern Africa on the external services of Radio Zambia, Comrade Khumalo was recalled to Zambia to join the radio unit of the ANC. His broadcasts in Zulu, were a popular feature on our programmes. He met his death whilst serving our organisations and struggle in this important capacity.

His remains were laid to rest in Lusaka.
