"In 1943, up to four million Bengalis starved to death when Churchill diverted food to British soldiers and countries such as Greece while a deadly famine swept through Bengal." https://www.independent.co.uk/news/world/world-history/winst...

"Thousands were sent to British run concentration camps during the Boer wars. Churchill summed up his time in South Africa by saying “it was great fun galloping about”."
