In Horn of the Hunter, Robert Ruark describes two Cape buffalo he took on his first safari, in 1951, in (then) Tanganyika with Harry Selby.

The first was wounded and gave the pair a hell of a time until he finally succumbed. The second, which had much bigger and more massive horns, was also wounded, and disappeared into a dense thicket. Selby and Ruark looked at each other, then sat down to smoke a cigarette. As the minutes wore on, Ruark became more and more anxious about what was to come. Then Selby invited him to accompany him as he went after the buffalo — a serious compliment as you know if you’ve ever been in that situation. Ruark steeled himself, checked his .470, and off they went. The tracking took some time. It probably seemed much longer than it was, but that’s the way these things work, as they crept along, expecting a charge at any second.
