This is a fascinating study of one of the more obscure aspects of Britain's WW1 campaign. It is an entertaining read describing how a Biritsh expeditionary force led by a commander considered a liability by every other section of the military somehow led his men to complete their objectives, and ultimately to wrest control of Lake Tanganyiki from Germany. The main character, Spicer, is like a comic book Captain Mainwaring, constantly boasting of his hunting and military exploits despite evidence to the contrary, and is eventually recalled to Britain after falling out with Britain's Belgian allies. The actual story of Mimi and Toutou (Spicer's two boats) is well written and engrossing but the book flags badly at the end with an over lengthy chapter on the film "African Queen", which was partly based on the story of Mimi & Toutou, and a tour of the region by the author, both of which would have been better served by a separate book. Still, an easy read and very entertaining.
