Demanding remarkable coordination with the Navy and the blockade, the campaign was critical in forcing the action inland. The letters also contain opinions on the 1864 election, the Emancipation Proclamation, the Florida expedition, the siege of Petersburg, life in a New York City hospital ward (Thomas Jones was wounded and lost an arm in the assault on Battery Wagner, made famous in the movie Glory), and on Lincoln's death.
Brothers 'til Death offers a view of the Civil War from the perspective of the frontline soldier. It provides insights into a forgotten theater of the war, the coastal campaign of the Carolinas and Georgia, providing new witnesses to assaults on Forts Pulaski, Wagner, and Fisher. Finally, the letters give new dimensions to what life was like for Irish soldiers fighting for the Union along the coastline of the South.
