When Stanley slogged through the Congo on his Emin Pasha Relief Expedition, Casement accompanied him for a week. "A good specimen of the capable Englishman," noted the explorer in his journal, not noticing that Casement was Irish. Casement was a better judge of Stanley, for although the explorer remained something of a hero to him, Casement recognized Stanley's sadistic streak. After seeing that Stanley's dog lacked a tail, he learned to his horror that Stanley had cut off the tail, cooked it, and fed it to the dog to eat.
