"Grass" by Carl Sandburg is a poem filled with depth and complexity. The beginning line of the poem stating, "Pile the bodies high at Austerlitz and Waterloo" (Sandburg, Carl line 1) shows that there were several bodies left over from war. This historical allusion has a colorful meaning because Austerlitz and Waterloo were two horrific warzones. The bodies are "shoveled under" at those places because there were too many bodies to give a proper burial.
"I am the grass; I cover all."
