In the middle of the cemetery is a grassy plane, strangely vacant. There are no granite tombs or crumbling concrete, just a sun-washed treeless patch of green known as "No Man's Land." Here 1,500 unidentified bodies are buried. At one time, their skin burned with yellow fever; now they lie in a cool, dark place where long ago their arms and legs, hands and feet, were intertwined for eternity.
