Civil War Battle

I was fighting in a civil war battle on the Northern side.  The battle went bad and a group of us had to leave and try to get back home.  Since there were so many people searching for us we had to stick to shadows and bushes.  We found a large hedge next to a house that was a perfect hiding spot.  I noticed that the Southern side was starting to make some technological advances, mainly automobiles.  They started riding around in highly decorated cars that were souped up and very fast.  Pretty soon they lost interest in fighting and were just racing their cars around.  That was when we all headed home.
