Q: Question: What was the population of Sierra Leone the first year Fingland served as High Commissioner there? Passage:In 1964 Fingland was posted to Rhodesia as Deputy High Commissioner, and was still there in November 1965 when Ian Smith signed the Unilateral Declaration of Independence and a state of emergency. The British High Commissioner has to leave and Fingland stayed on as head of the residual mission until he was also expelled in 1966. He was then posted as High Commissioner to Sierra Leone 196669, an unstable time during which there were three military coups.
