Absolutely. The curve of the ground is such that as you emerge from the wood line the ground rises in front of you for another 50 yards. When I lead trips through here I have my guests inside Doles trenches and crouch down a bit as if they were behind a defensive work. I then rumble my fat ass out of the wood line and have them shout when they see the top of my head. In almost every case it is between 150 and 145 yards. I am 6 foot so I am about 5 inches taller than your average ACW soldier.
So before the Confederates could effectively react the column is 100 yards away and running.....no shouting and no shooting. The front rank does not even have their rifles capped. Before many shots ring out the Federals are up and over the parapet.
