About Us


Historical Significance and Authenticity

Our event takes place on part of the actual site of John C. Fremont's  44,000+ acre Las Mariposas federal land grant.  Active in Missouri and other places during the Civil War, many of our streets and buildings are named after he and his family since they settled here.  Additionally, Mariposa itself is chocked full of a history of its own, including the gold rush, and many other important times in California's past. 


Beautiful authentic location

 Our extraordinary event takes place on over 60 acres of land which resembles actual battlefield locations, as attested by prior  reenactors.  Inhibited only by your imagination, our site has wide open spaces with trees, draws and a ravine.  Here the cavalry  lope their horses, cannon fire rages, and battle tactics and stategies are limitless in their potential.  Overall, you couldn't ask for a better locale. 


Authentic Suttler's merchandise

We are extremely excited this year to welcome a host of sutlers to our event.  These Sutlers provide nothing short of the most authentic merchandise for Reenactors and event guests.  This year we are looking forward to more Sutlers joining us from around the USA!
