Sunrise on the Hills
Battle metaphor
Longfellow turns morning clouds into a defeated army—'hosts in battle overthrown.' This epic simile is pure Romantic convention, making nature theatrical.
Storm damage
These aren't healthy trees—they're 'blasted' (lightning-struck) and 'cleft' (split). The mountaintop is a battlefield of weather.
Bittern's flight
The bittern is a marsh bird known for its booming call. 'Spiral way' describes how it circles upward—Longfellow adding one precise natural detail among the generalities.
Human sounds enter
The poem shifts here from pure nature to civilization—church bells, hunting horns, gunshots. Notice how these sounds are 'music' and 'merry,' not intrusions.
Direct address
Sudden pivot to 'thou'—the reader. After 30 lines of landscape description, Longfellow reveals this was all sermon preparation.
