Close Little Wars is a set of free wargames rules adapted from Donald Featherstone’s 1962 War Games book.
Chronofus has written a wargamers’ guide to Napoleonic Austria. He writes:
This document is a wargamer’s guide to Austria in the disastrous campaign against France in 1805, written to suit the Elan rules system. This is not intended to be an in depth detailed study of the campaign, which must be left to Europeans with good access to archival material. Enough information is presented here to give an overview of the campaign itself and enough formation and uniform details for a wargamer to suitably paint and base their miniatures to a reasonable standard. There are enough vagaries in some units for perfectionists to require further details from more in depth historical analysis. The reader is also cautioned that there has been, and continues to be, alot of misinformation about the Austrian army. Many parts of this campaign where Napoleon was not present have also been conveniently buried in history. As far as practical this document has been verified against current research.
Steve Winter has a nice photo essay of battlefield sites taken during his 2001 trip across the Northern plains. He visited teh sites of the Little Bighorn, Fort Phil Kearny, the Fetterman Massacre, and the Wagonbox Fight.
The Library of Congress has an incredible archive of film footage from the Spanish American War.
This presentation features 68 motion pictures produced between 1898 and 1901 of the Spanish-American War and the subsequent Philippine Revolution. The Spanish-American War was the first U.S. war in which the motion picture camera played a role. These films were made by the Edison Manufacturing Company and the American Mutoscope & Biograph Company and consist of actualities filmed in the U.S., Cuba, and the Philippines, showing troops, ships, notable figures, and parades, as well as reenactments of battles and other war-time events. The Special Presentation presents the motion pictures in chronological order together with brief essays that provide a historical context for their filming.
It’s inspired me to get out some of my old Spanish American 15mm miniatures for a game.
I know you won’t believe me, but there’s more to painting Austrian Napoleonic uniforms than endless seas of white. You can find more details in the uniform guide here.
