The Rhodesian Bush War (or Second "Chimurenga"), which had been underway at a low level since before UDI, began in earnest in December 1972 when ZANLA attacked farms in north-eastern Rhodesia. The Rhodesian Security Forces mounted a strong counter-campaign over the next two years. Muzorewa re-engaged with Smith in August 1973, accepting the 1971–72 Douglas-Home terms, and the two signed a statement to that effect on 17 August. The UANC executive repudiated this in May 1974, but talks between Smith and Muzorewa continued sporadically. The RF again won a clean sweep of the 50 white seats in the July 1974 general election.
