"On the American Dead in Spain" by Ernest Hemingway
"The dead sleep cold in Spain tonight. Snow blows through the olive groves, sifting against the tree roots. Snow drifts over the mounds with small headboards. (When there was time for headboards.) The olive trees are thin in the cold wind because their lower branches were once cut to cover tanks, and the dead sleep cold in the small hills above the Jarama River. It was cold that February when they died there and since then the dead have not noticed the changes of the seasons...The Spanish people will rise again as they have always risen before against tyranny.
The dead do not need to rise. They are a part of the earth now and the earth can never be conquered. For the earth endureth forever. It will outlive all systems of tyranny.
Those who have entered it honorably, and no men ever entered earth more honorably than those who died in Spain, already have achieved immortality." ~Ernest Hemingway, 1939
