It has become a modern orthodoxy that Europe's 20th century was the bloodiest in history and that atrocities must be recorded and remembered by society as a whole. But while a Black Book of Communism has been compiled and everybody is aware of the horrors of nazism, popular historians have been surprisingly uninterested in the dark side of the British Empire. There are exceptions, such as Mike Davis's powerful Late Victorian Holocausts, but much else still lies buried in the academic literature. Davis and others have estimated that there were between 12 and 33 million avoidable deaths by famine in India between 1876 and 1908, produced by a deadly combination of official callousness and free-market ideology. But these were far from being a purely Victorian phenomenon. As late as 1943 around 4 million died in the Bengal famine, largely because of official policy.
No one has even attempted to quantify the casualties caused by state-backed forced labour on British-owned mines and plantations in India, Africa and Malaya. But we do know that tens of thousands of often conscripted Africans, Indians and Malays - men, women and children - were either killed or maimed constructing Britain's imperial railways. Also unquantified are the numbers of civilian deaths caused by British aerial bombing and gassing of villages in Sudan, Iraq and Palestine in the 1920 and 1930s.
Nor was the supposedly peaceful decolonisation of the British Empire without its gory cruelties. The hurried partition of the Indian subcontinent brought about a million deaths in the ensuing uncontrolled panic and violence. The brutal suppression of the Mau Mau and the detention of thousands of Kenyan peasants in concentration camps are still dimly remembered, as are the Aden killings of the 1960s. But the massacre of communist insurgents by the Scots Guard in Malaya in the 1950s, the decapitation of so-called bandits by the Royal Marine Commandos in Perak and the secret bombing of Malayan villages during the Emergency remain uninvestigated.
