While training as a teacher, Potlako Leballo (PK) was only sixteen when he volunteered for active service at the start of World War II. Twice taken prisoner in North Africa he was court-martialled for objecting to discrimination against black South African soldiers. Initially a member of the ANC Youth League, he broke away with Robert Sobukwe to form the PAC, becoming Second in Command and Chief of its military wing, APLA-POQO. He was living in this house while planning the pass law protest at Sharpeville for which he was jailed for two years. PK was banished to Vryburg, but chose to return to Lesotho, the land of his birth.
