What does Eroica's opening remind you of?

Whenever I hear the first movement of Beethoven's 3rd symphony, I sense images of destruction in a bright and blue sky; I sense green pastoral fields (sorry 6th). I can't quite put my finger on the exact scenario or concept that it feels like though. What simile would you give it? It would help me verbalize my feelings towards it.

It's some uncannily harmonious integration of adversity and beauty.
