For anyone with 30 minutes to spare, I strongly recommend listening to Ed Paice’s talk at the King’s African Rifles recent dinner. It can be found on Youtube (Many thanks to @Thinking_Major and @AfricaResearch for drawing it to my attention).
Without giving too much away, Paice discusses the King’s African Rifles’ involvement over 1916 and 1917 leading into 1918 focusing specifically on two actions – Mahiwa and Liome (Portuguese East Africa). Using statistics and accounts from the time, he demonstrates how the KAR were a force to be reckoned with supporting the case I tried to make in Misconception 2 using only Lettow-Vorbeck’s words.
The question he provocatively asks at the end is one I know many have asked and for which, we’ll never know the answer. It’s definitely time to remember Africa for its involvement and sacrifice in World War 1.
