That is a statement that I was not aware of. I will have to research this reference. I am curious as to how this figure was obtained. I don't doubt the validity of the figure because of the numbers of slaveholders in the Union Army from Missouri and Kentucky, including Lt. General U. S. Grant himself. Whereas southern slave owners were exempted from conscription under the 20 slave laws. But it is one of those facts that will never be accepted by our Unionist friends. It contridicts their templete for the war.
