Taken at Kennesaw Mountain National Battlefield Park.  Union troops fought their way up the hill but were repulsed at the crest by artillery positions that had been hidden. Brigade Commanders Harker and McCook (of Illinois) were killed in the attack that cost 3000 casualties in less than an hour with no penetration of the defenses.

I liked the light on the cannon framed by the forest.  So peaceful with such a violent past.
