What can be deduced from looking at the background?
about the season
Leaves on the trees indicate that it is either later spring, summer, or early fall.
from the lone tree in the left side of the picture
The lower section of a tree in a forest will be bare because of the lack of light.
A tree such as this, standing by itself, indicates that many trees around it were
recently cleared. This area might have been cleared by the troops to prepare for the coming battle.
from the light strips on the ground
These are probably roads. They may have been recently cleared by the troops, or they might
have been used by previous occupants of the land.
