I think these books are some of the ones referenced above. It is worth looking through the rest of the range as there is a lot of interest for any enthusiast of Spanish military history - especially on the WSS and even one on the eponymous war of Jenkins' Ear!
You can order them in safety from this site
http://www.atlanticajuegos.com/It is almost worth a visit to Madrid just to visit this shop - it is a wargamer's paradise, a real Ali Baba's Cave of goodies (the last time I was there I had to have part of the loot shipped home - there was no way any airline was going to let me on board with all that excess baggage! Not only that but they are lovely, helpful people!
If you don't fancy that option you should be able to get the books through Iberlibros -the Spanish incarnation of ABE Books…
The last book I have not seen but I shall rectify that asap.. it features the art of Spain's leading military artist and is smack on topic!
