For many years, George’s Nafziger’s collection of orders of battle for conflicts dating from the 1600s to the 1900s have been a mainstay of the historical wargaming community.
Once available only commercially, Nafziger recently donated his collection to the Army’s Combined Arms Research Library.
The actual files are available as pdfs here. But as they’re numbered and not named, you’ll also want to consult the finding aid here. And a search function.

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!!
D6 Shooters is a solo Old West Campaign game. The format could be adapted to a wide variety of periods and settings.
The d6 Shooters are a famous Old West posse, and you are their leader. In this solitaire Print-and-Play series, you will lead your posse on several adventures and missions, using a Yahtzee-style dice system to gain resources, movement and perform other important actions. There is always danger near, and your journeys will be very challenging to complete, but there is also the potential for great reward with untapped gold deposits among the California lands where you travel.
Here are a page of downloadable, printable flags for your American Civil War games. They’re quite nicely done.
