Leonard Mosley would later write, however, "It was from these brilliant and fantastic Hottentots that Lettow-Vorbeck learned the Bushcraft that was to prove of such value to him in his war against the British in East Africa. When guerilla leader Samuel Isaak was captured and brought in for questioning, it was von Lettow who conducted the interrogations... His questions were how to live off a country which offers no apparent sustenance, how to run in conditions when most men barely have the strength to walk, how to condition the body to go without food or water, and most important of all, how to become so much a part, so absorbed into an unfriendly wilderness that survival is possible as the snakes and land crabs and lizards survive."
