Hidden in the valley's forest were five union regiments -- thousands of Carter's fellow soldiers.They had marched for thirty-six hours.Now they were resting.But at midnight they would climb that road up the rocky cliff.Their plan was to attack by surprise an army of southerners,camped on the other side of the cliff.But if their enemy learned about the Union Army hiding in the forest,the soldiers would find themselves in a trap with no escape.That was why Carter Druse had been sent to guard the road.It was his duty soldier,dressed in gray,spied on the valley,where the union army was hiding.
