Washington Duke was in his early 40s during the Civil War and remained out of it until Confederate conscription was raised to 45, and Duke, 43, went to war. He sent his children to the Roney home in Alamance County, except for Brodie who accompanied him into service.
Again, there is some question as to whether Duke was in the Navy or Army.
At some point,Duke decided to sell all his farm belongings and covert everything to tobacco by the end of 1863.
He was in the military only briefly and captured by U.S. forces and later imprisoned in Richmond, Virginia. At the end of the war, he was released and shipped to New Bern where he embarked on his 135 mile walk home.
