In the winter of 1864, Summerfield Hayes, a pitcher for the famous Eckford Club, enlists in the Union army, leaving his sister, a schoolteacher, devastated and alone in their Brooklyn home.

This rich back story is inter cut with scenes of his soul-altering hours on the march and at the front—the slaughter of barely grown young men who only days before whooped it up with him in a regimental ball game; his temporary deafness and disorientation after a shell blast; his fevered attempt to find safe haven after he has been deserted by his own comrades
