Whatever about my misgivings about W. S. Churchill as a military leader (pretty disastrous, despite his own romantic notions about military stuff and deep delusions about his own limited talents as a military leader), about his skills of political leadership (which, to be frank, were quite variable, running the gamut all the way from brilliant to truly awful), his political courage (unmistakable, genuine and rare), I must admit that you are absolutely right when you say that Churchill was a master of prose. He was. The man could write - and quite brilliantly, too.
Actually, for some of our friends Across The Pond, I feel I must point them in the direction of an extraordinarily readable history he wrote on the American Civil War. I was astonished when I read it as a child - my late father was fascinated by the American Civil War - an interest I shared with him as a child, and this book was one of several on the topic on our shelves.
