Letters, typescripts, typescript notes, and related printed materials. Most of the collection consists of typescript notes compiled by Pratt in the preparation for his book STANTON, LINCOLN'S SECRETARY OF WAR. The notes chiefly relate to the Civil War. It is not always possible to determine the source of a given note. There are 17 letters to Pratt which relate to his book, most of them from Gideon T. Stanton. Also, typescripts for three other books by Pratt: THE EMPIRE AND THE GLORY (N.Y., Sloane, 1941) on the Napoleonic campaigns; ORDEAL BY FIRE (N.Y., Sloane, 1948) on the Civil War; ELEVEN GENERALS; STUDIES IN AMERICAN COMMAND (N.Y., Sloane, 1949). Each of these typescripts has handwritten corrections and instructions for the printer. The printed materials include earlier serial versions of ELEVEN GENERALS and travel brochures and maps of Civil War sites used by Pratt in his research on Stanton.
