Mr. Lincoln's T-mails

Abraham Lincoln's two great legacies to history-his extraordinary power as a writer and his leadership during the Civil War-come together in this close study of the President's use of the telegraph. Invented less than two decades before he entered office, the telegraph came into its own during the Civil War. In a jewel-box of historical writing, Wheeler captures Lincoln as he adapted his folksy rhetorical style to the telegraph, creating an intimate bond with his generals that would ultimately help win the war.
