ZANLA were unable to totally capitalise on the situation, however, because of internal conflict which had started earlier in 1974. Some ordinary ZANU cadres perceived the ZANU High Command members in Lusaka, the Zambian capital, to be following a luxurious lifestyle, contrary to the party's Maoist principles. This culminated in the Nhari rebellion of November 1974, in which mutinous guerrillas were forcibly put down by the ZANU defence chief, Josiah Tongogara. The ZANU and ZAPU leaders imprisoned in Rhodesia were released in December 1974 as part of the "détente" deal. Robert Mugabe had been elected ZANU president while they were incarcerated, though this was disputed by its founding leader, the Reverend Ndabaningi Sithole, who continued to be recognised as such by the Frontline States. On his release, Mugabe moved into Mozambique to consolidate his supremacy within ZANU and ZANLA, while Sithole prepared to take part in talks with the Rhodesian government as part of the UANC delegation. Sithole retained the ZANU leadership in the eyes of the Frontline States until late 1975. The Victoria Falls Conference According to the terms agreed in December 1974, the talks between the Rhodesian government and the UANC were to take place within Rhodesia, but in the event the black nationalist leaders were loath to attend a conference on ground they perceived as not neutral. The Rhodesians, however, were keen to adhere to the accord and meet at a Rhodesian venue. In an effort to placate both sides, Kaunda and Vorster relaxed the terms so that the two sides would instead meet aboard a train provided by the South African government, placed halfway across the Victoria Falls Bridge, on the Rhodesian–Zambian border. The Rhodesian delegates could therefore take their seats in Rhodesia and the nationalists, on the opposite side of the carriage, would be able to attend without leaving Zambia. As part of the détente policy, Kaunda and Vorster would act as mediators in the conference, which was set for 26 August 1975. The UANC delegation was led, as expected, by Muzorewa and included Sithole representing ZANU, Nkomo for ZAPU and James Chikerema, the former ZAPU vice-president, for a third militant party, the Front for the Liberation of Zimbabwe. According to Rhodesian intelligence, the various nationalist factions had not patched up their differences, were not prepared to accept Muzorewa as their leader and, to this end, were hoping that the conference failed to produce an
