I saw this on YouTube – German East Africa – World War 1 Colonial Warfare I THE GREAT WAR Special – YouTube Video The Great War: https://www.youtube.com/watch?v=P1KzBDjr-Ys (about 9:13 minutes long).
I will be doing a series on World War I posts that cover the non-Western Front campaigns – Eastern Front, Africa, Asia. These are areas that rarely received coverage. I took a World War I course years ago and the coverage outside of the Western Front and U-boats was sparse at best and non-existent at worst. I am by no means a World War I expert. I will look for other bloggers and vloggers who cover some of the campaigns, but expect I may have to do my own research as well. The Great War YouTube may be a good source of videos and a starting point for my own research.
