This compact history was produced by a Parisian-born, English-educated American military historian in the early years of the 20th century. Despite its age it's written in a very approachable style and is a no-nonsense, what-happened-next account of the Revolution with just enough background to give an understanding of what is going on and why. You won't find any great insights into the social, political and economic processes, but you will get a well-told account of one of modern Europe's most significant formative events.
The Kindle version has been done well; not perfect certainly, but free from the major formatting problems which sometimes beset digital versions of ancient out-of-contract works. In amongst a sea of downloadable dross this is one freebie that can be recommended.
