Here are images from the Casini Ranch Duncans Mills, Sonoma County California, Civil War Days reenactment held on September 17, 2004.
If you've never attended a Civil War re-enactment, treat yourself the next time you have a chance.
You'll be astonished and amazed at the accuracy and level of detail displayed by these afficianados, and their painstaking recreation of a defining time in United States history.
You might even discover units (like we did) from armies that may have been comprised of your ancestors.
