Example input: Passage: The French and Indian War (1754–1763) was the North American theater of the worldwide Seven Years' War. The war was fought between the colonies of British America and New France, with both sides supported by military units from their parent countries of Great Britain and France, as well as Native American allies. At the start of the war, the French North American colonies had a population of roughly 60,000 European settlers, compared with 2 million in the British North American colonies. The outnumbered French particularly depended on the Indians. Long in conflict, the metropole nations declared war on each other in 1756, escalating the war from a regional affair into an intercontinental conflict.

Q: The capture of Warũhiũ Itote (aka General China) on 15 January 1954 and the subsequent interrogation led to a better understanding of the Mau Mau command structure. Operation Anvil opened on 24 April 1954, after weeks of planning by the army with the approval of the War Council. The operation effectively placed Nairobi under military siege, and the occupants were screened and the Mau Mau supporters moved to detention camps. The Home Guard formed the core of the government's strategy as it was composed of loyalist Africans, not foreign forces like the British Army and King's African Rifles. By the end of the emergency, the Home Guard had killed 4,686 Mau Mau, amounting to 42% of the total insurgents. The capture of Dedan Kimathi on 21 October 1956 in Nyeri signified the ultimate defeat of the Mau Mau and essentially ended the military offensive. During this period, substantial governmental changes to land tenure occurred. The most important of these was the Swynnerton Plan, which was used to both reward loyalists and punish Mau Mau.
A:
When was Waruhiu Itote captured?
