Operation Anvil (Mau Mau Uprising) Many Kikuyu were sympathetic to the Mau Mau cause and provided the insurgents with supplies. They also housed them, thereby facilitating attacks in the city and the neighboring Kiambu District. In June General George Erskine was dispatched to Kenya to assume control over British forces. He immediately began instituting reforms and organised a series of attacks against the Mau Mau. In January 1954 the British captured rebel leader Waruhiu Itote, who gave them critical information about Mau Mau deployments and strategy under interrogation. Two months later the colonial command structure was overhauled, increasing decision-making efficiency and granting Erskine greater influence
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.
