I studied the restoration of Charles II during my Masters research. My focus was on George Monck, by far the most interesting character in my mind, maybe because he seems something of a silent type who when he acts, acts decisively. I also believe that his actions were never as clear as history now suggests them to be, for instance I suspect that had the situation presented itself differently, he might well have made himself king or Lord Protector, rather than facilitating the return of the Stuarts.
In any case I write this for two reason. Wonders & Marvels has a Merry post about Charles II and his string of mistresses written by novelist Susan Holloway Scott and it got me to thinking and searching the web for material on Monck which resulted in discovering this site which is planning to Monck’s Observations upon Military & Political Affairs.
As per usual though little searching on Google Books and the disappointing result is that although copies have plainly been scanned and although the book is WELL out of copyright, it is not available for full view. A real shame.
