The Tsavo Man-Eaters were a pair of man-eating male lions in the Tsavo region of Kenya, which were responsible for the deaths of many construction workers on the Kenya-Uganda Railway between March and December 1898. The lion pair was said to have killed 135 people. While the terrors of man-eating lions weren't new in the British public perception, the Tsavo Man-Eaters became one of the most notorious instances of dangers posed to Indian and native African workers of the Uganda Railway. They were eventually killed by Lieutenant Colonel John Henry Patterson, who wrote his account of his hunting experience in a semi-biography The Man-Eaters of Tsavo. Today, the Tsavo Man-Eaters are the most widely studied man-eating pantherine cats given their behavior of hunting humans as a pair as well as dental injuries reported in one of the lions, a cause commonly attributed to big cats turning to humans as prey. Historical information The killings start As part of the construction of a railway linking Uganda with the Indian Ocean at Kilindini Harbour, in March 1898 the British started building a railway bridge over the Tsavo River in Kenya. The building site consisted of several camps spread over an area of , accommodating the several thousand mostly Indian workers. The project was led by Lieutenant-Colonel John Henry Patterson, who arrived just days before the disappearances and killings began. During the next nine months of construction, two maneless male Tsavo lions stalked the campsite, dragging workers from their tents at night, devouring them. There was an interval of several months when the attacks ceased, but word trickled in from other nearby settlements of similar lion attacks. When the lions returned the attacks intensified, with almost daily killings. Crews tried to scare off the lions and built campfires and bomas, or thorn fences made of whistling thorn trees around their camp for protection to keep the man-eaters out, all to no avail; the lions leaped over or crawled through the thorn fences. Patterson noted that early in their killing spree only one lion at a time would enter the inhabited areas and seize victims, but later they became more brazen, entering together and each seizing a victim. As the attacks mounted, hundreds of workers fled from Tsavo, halting construction on the bridge. At this point, colonial officials began to intervene. According to Patterson, even the District Officer, Mr. Whitehead, narrowly escaped being killed
