I really like the concept of your photograph. I can see symbolism that denotes the emotions of people looking at the battleground or even giving their opinions of war.
I'm a fan of battlefields and the split rail fences - so I automatically like your image. Good saturation and I like the sunlight filtering through the clouds. Nice countryscape.
Great shot. The dark sky really brings a foreboding feeling. Very good title. I would like to see it in sepia tone. I think that might lend it a real 1865 feel.
The shot could have been a little underexposed as the texture of the top of fence braces gets lost, but that is a real nit.
