I must confess to have been considering acquiring the above title for some time and earlier this week - by virtue of eBay - managed to do just that!
I was pleasantly surprised by the scope of the content of the book mainly because it seemed to be so well laid out. You have an overview of the period, a suggested set of rules (which have 'use then with the blocks!' written all over them - as Mr. Hardman and others have pointed out), a set of army lists - useful for reference - and a number of historical scenarios spanning the era.
The rules look quite interesting and would be eminently suitable for use with the blocks as they are base driven.
Coming as this does on the back of my recent acquisition of the book on the Swiss Civil War of 1847 (Three Weeks in November by Ralph Weaver) I now have even less excuse for not attempting a game from this period of history!
In closing the pictures are top drawer and very inspiring and cover some surprising topics (the Carlist War or even the war of 1864 with Denmark anyone?). My only observation is that it would have been nice to have seen a game from the Russo-Turkish War of 1877 but then that is just me!
