On our way north to Washington DC, we stopped in Fredericksburg, VA at the Fredericksburg National Military Park. This one was unique because it was a Confederate win. It was quite a sad story of a great location for the Confederate soldiers behind a wall and sunken road, and the following slaughter of Union soldiers. There was a house nearby with bullet holes in the walls from the battle. We also visited the beautiful Chatham Manor, a nearby mansion that overlooks Fredericksburg. It was a plantation, then headquarters, then hospital for soldiers, visited by Washington and Jefferson.
And the kids did the Junior Ranger program there as usual.
