Pierce won the election and, in 1853, made Davis his Secretary of War. In this capacity, Davis gave to Congress four annual reports (in December of each year), as well as an elaborate one (submitted on February 22, 1855) on various routes for the proposed Transcontinental Railroad. The Pierce Administration ended in 1857. The President lost the Democratic nomination, which went instead to James Buchanan. Davis' term was to end with Pierce's, so he ran successfully for the Senate, and re-entered it on March 4, 1857.
