Here’s how the items in the passage can be categorized:
Simile:
- "That he could hear, like a sentinel's tread,"
- "On the rising tide, like a bridge of boats."
Metaphor:
- "Beneath, in the churchyard, lay the dead./ In their night encampment on the hill,"
Personification:
- "The watchful night-wind, as it went/ creeping along from tent to tent,/ and seeming to whisper, 'All is well!'"
- "The watchful night-wind, as it went.... seeming to whisper, 'All is well!'"
Note that the last two entries refer to the same personification of the night-wind, emphasizing its watchfulness and ability to whisper.
