Their guide was Philip Hope Percival, who also hunted with Theodore Roosevelt in 1909. During the safari, Hemingway became so severely ill that he had to be transported to a hospital in Nairobi by plane. He later described the event in his short story “The Snows of Kilimanjaro.” The trip also inspired him to write the novel “Green Hills of Africa,” which received average critical acclaim, and the short story “The Short Happy Life of Francis Macomber.” Despite the illness, Hemingway’s safari trophies included a lion.
