Armies of the War of the Pacific

I've just downloaded this as a guide to the land side of the War of the Pacific, to help me get a grip on the key stages of the conflict for my naval games. I know not a lot about the war itself beyond the actions of the Chilean and Peruvian navies, so this should fill in the gaps and give me a better understanding of the major battles, sieges and other significant events. I am sorely tempted to get hold of It's Getting A Bit Chile too, as I've read really positive things about the rules and also like the Spanish Civil War rules by the same author, but I will have to resist otherwise I'll be ordering  lots of 10mm stuff from Pendraken again!
