Your proposition to procure the exchange of other prisoners for prisoners at Richmond is respectfully declined, the sole object in entering into this negotiation being to procure the release of men belonging to my command who are held as prisoners by you.

Your proposition that each party shall release all citizens who may have been captured on account of their sentimens or opinions merely meets the approbation of my jundgment, but as I hold no prisoners of that class it is unnecessary to discuss the proposition and I can only hop that as the suggestion comes from you, you will in the interest of humanity and the "principles of toleration of opinion" act upon the suggestion.

Respectfully, &c.,

W. H. L. WALLACE,

Colonel, Commanding U. S. Forces at Bird's Point.
