" The Wilderness and Spottsylvania battles convinced me that we had more artillery than could ever be brought into action at any one time. It occupied much of the road in marching, and taxed the trains in bringing up forage. Artillery is very useful when it can be brought into action, but it is a very burdensome luxury where it cannot be used. Before leaving Spottsylvania, therefore, I sent back to the defences of Washington over one hundred pieces of artillery, with the horses and caissons. This relieved the roads over which we were to march of more than two hundred six-horse teams, and still left us more artillery than could be advantageously used. In fact, before reaching the James River I again reduced the artillery with the army largely. "
