NYT Disunion Civil War Articles this one on Volunteer nurses.

This from the memoirs of Nurse Cornelia Hancock:

The next day, July 7, was considerably worse. Having learned that the wounded of the 12th New Jersey, a regiment from their area, were at the Second Corps’ field hospital about five miles away, Hancock’s group determined to go there to minister to familiar faces. “As we drew near our destination,” she wrote,

"we began to realize that war has other horrors than the sufferings of the wounded or the desolation of the bereft. A sickening, overpowering, awful stench announced the presence of the unburied dead, on which the July sun was mercilessly shining, and at every step the air grew heavier and fouler. Not the presence of the dead bodies themselves, swollen and disfigured as they were, and lying in heaps on every side, was as awful to the spectator as that deadly, nauseating atmosphere which robbed the battlefield of its glory, the survivors of their victory, and the wounded of what little chance of life was left to them."
