You guys are way too clever - correct answer in the very first resposne! Yes, these figures are for the Paraguayan War, aka the War of the Triple Alliance, which was fought from 1864 to 1870. I've just finished reading a short synopsis of the war and it sounds a pretty horrid affair. It was a diasaster for Paraguay as some 40% of its population died (including a large number of civilians who died from disease imported by its enemies' armies). The destruction of Paraguay's male population resulted in its later armies consisting largely of children and old men. The battles appear to include a few stand-up fights but lots of sieges and assaults on entrenched positions. I'll have to do more reading to work out exactly what gaming opportunities are presented by this period, but it falls squarely within "my kind of thing": off beat period, nice figures, colourful uniforms (gaucho cavalry!). I wonder what the terrain would look like; I'll have to do some digging on that too.
The figures are from a new company called Kingscarbine Miniatures. Nuno, the proprietor, is well known to First Carlist War gamers. He recently posted a proposed list of figures for this range on TMP - if the project continues this should be pretty comprehensive. I just hope that the project is viable - there have been lots of new ranges recently that produce a handful of packs and then go quiet. So whilst I have plenty on my painting plate at the moment (or should that be "palette"?), I'm happy to give this project some support. I bought 1 each of the packs in the initial release and will aim to have those painted by the end of the month. I seem to be butterflying quite badly at the moment; not sure why.
