In 1865, US Representative William B. Allison and Senator James Harlan wrote to Lincoln's Secretary of War asking for Stibbs' leave of absence to be extended (click image for larger view):

Apparently the matter was referred to the President, who noted his approval on the back of the letter:

The Louisiana Research Collection preserves extensive Civil War holdings, including the papers of Confederate President Jefferson Davis, and Generals Albert Sidney Johnston and Stonewall Jackson. In addition, we have many papers, diaries and letters both of Confederate soldiers from Louisiana and Union soldiers who served in Louisiana. As the 150th anniversary of the American Civil War approaches, we plan to continue highlighting our Civil War archives, acquisitions, and increasingly, our digital collections.
