“The ground, for acres, was a thinly wooded slope--and among the trees on the leaves and grass, were laid the wounded who were pouring in by scores of wagon loads, as picked up on the field under the flag of truce... How we watched and pleaded and cautioned as we worked and wept that night! How we put socks and slippers upon their cold, damp feet, wrapped your blankets and quilts about them, and when we had no longer these to give, how we covered them in the hay and left them to their rest…” —Clara Barton, 1863
