Letter from S. Trumbell to Abraham Lincoln, with Response

This letter contains a brief recommendation from S. Trumbell regarding another letter writer. This other writer was likely a Confederate, possibly a soldier seeking to be released from prison. The oath Lincoln refers to was in the Proclamation of Amnesty and Reconstruction, which Lincoln issued on December 8, 1863. This proclamation allowed for the pardon of all but high ranking Confederates. Lincoln approved the discharge in this case.
