For over a century, lost in the inner recesses of a New Jersey library, lay the diary and letters of a young man who fought for the Union in the Civil War. Lt. Edmund Halsey, a college graduate, fledgling lawyer, and accomplished writer, kept one of the most comprehensive diaries of the war. From 1862-1865, he wrote hundreds of letters to his father, sisters, brothers, and girlfriend, Mary.

As the Civil War divided a nation, so it divided a family: Lt. Edmund Halsey fought against his brother, Joseph Halsey, who sided with the Confederacy.The papers of Edmund and Joseph Halsey offer a rare glimpse into the lives of two brothers, north and south, tossed into a conflict that destroyed families and tore apart an entire nation.
