Final answer:
The first event is when Farquhar's wife brings the soldier water.
Step-by-step explanation:
The event that happens first in the true sequence of events described in the excerpts is when Farquhar's wife brings the soldier water. This interaction occurs before the plot advances to Farquhar standing on the Oak Creek bridge with a rope around his neck, and long before the eventual fall into the water and the hallucinated escape to greet his wife.
