The South American Wars of Liberation are a fascinating part of overall the Napoleonic wars, and provide the potential for very colourful Napoleonic battles in the New World. Set in the period starting in 1810, and running up to 1830, these wars covered the breadth of Spain's crumbling American empire, with the key campaigns set in the North around modern day Venezuela, in the South in Argentina, Chile and finally in the North West/centre in Peru, as well as in Mexico.
I wanted to provide a list of books and sources which I think can provide a quick and entertaining introduction to the period, the tactics and ideas about how to wargame them. Probably the first book I came across was The Armies of Bolivar and San Martin by Terry Hooker. This Osprey book is a great little introduction to the period, and gives a broad outline of the campaigns and uniforms (and the illustrations are excellent).
The masterpiece in terms of it scope and depth of detail for the Wars of Liberation has to be "Liberators" by Robert Harvey. This covers all the major campaigns and battles from Mexico to Tiera Del Fuego, from the beginning of the Republican movement under Miranda to the death of Simon Bolivar in 1830, and the abdication of the Emperor Pedro in Brazil in 1831. I cannot recommend the book enough as a Tour de force history of the wars.
Of more specific and recent interest is the newly published "Conquer or Die!" by Ben Hughes. Focusing solely on the exploits of the British (and Irish) Legions in the wars. This is clearly geared towards military historians (and wargamers), and presents each of the battles and campaigns of the Legion in its various forms and amalgamations, including detailed battle maps and orders of battle (OOBs) where available.
There is also an additional Supplement that goes along with this that you can purchase as a PDF.
I believe John Fletcher has another book in the pipeline that will focus solely on the Northen campaigns of Simon Bolivar and his generals. These can be purchased directly from Grenadier Productions (see link on left).
