Answer
As a success, Paul von Lettow-Vorbeck's campaign is viewed by historians because he successfully avoided defeat despite the enormous odds against him. Von Lettow-Vorbeck was outnumbered and outgunned by the Allies, but he was able to use his superior knowledge of the terrain and his tactics to outmaneuver his opponents. He also won the support of the local population, who helped him to gather intelligence and supplies.
