Here’s a neat photo album – history of the US Philippine War 1899 – 1902.
The Photographic History of the Civil War is a classic work available now as an ebook, in pdf format and in other ways online.
Thanks to reader FNH for the tip!!
The Veni Vidi Vici site has some great photos of Dark Ages miniatures. I’m painting a variety of Dark Ages armies and always like to reference other peoples’ painting projects. These are really good.
Redjack has an attractive photo gallery of figures from the late, but great Warzone game. I’ve got a ton of those figures myself.
There also are a couple of Warzone scenarios and house rules
The Valeur et Discipline site has some terrific eye candy of 25mm Napoleonic figures. My dream is to have a collection of such figs.
