Mau Mau Uprising perpetrated by Kenyan security forces who were partially overseen by British commanders. Official estimates place the death toll from the first Lari massacre at 74, and the second at 150, though neither of these figures account for those who 'disappeared'. Whatever the actual number of victims, "[t]he grim truth was that, for every person who died in Lari's first massacre, at least two more were killed in retaliation in the second." Aside from the Lari massacres, Kikuyu were also tortured, mutilated and murdered by Mau Mau on many other occasions. Mau Mau racked up 1,819 murders of their fellow native
Operation Anvil (Mau Mau Uprising) in the process. Erskine intended on relocating all Kikuyu, Embu, and Meru people from Nairobi, but the colonial government rejected the plan, citing potential harm to the local economy and administration. The operation was based on one British security forces had conducted in Tel Aviv, Palestine. Its legality was assured by the Emergency Regulations and the Control of Nairobi Regulations of 1954, the latter of which permitted the colonial governor to issue "Evacuation Orders" to remove and detain individuals from the city so they could be screened for connections with the Mau Mau. Four battalions were earmarked for the action.
