Tupelo is probably the smallest battlefield I've ever visited, or rather the officially preserved part is the smallest I've ever visited. This was on my first battlefield trip. We were on our way from Vicksburg to Shiloh and it said there was a park at Tupelo so we stopped. Its probably as big as the yard of my house. There is this one monument and two plaques. If you walk away from that understanding the battle better than you are truly talented.
The problem is that it appears Tupelo has grown a ton since the war and has paved over most of the battlefield. I saw on the Civil War Preservation Trust's website that there is an opportunity to purchase land where the battle ended on Mt Vernon Road. Those 12 acres will be nice but won't provide a ton of opportunity for interpretation, but any interpretation is better than the scant amount I saw the last time I was there.
