The Bluecoats - Volume 16 - Sallie

A quiet day in the Union Army … Soldiers are resting, Blutch and
Chesterfield are arguing, and the generals are plotting strategy.
Things change suddenly with the arrival of a new regiment, sent as
reinforcements to counter the imminent arrival of the Confederates.
With them is a young dog, Sallie, who’s been on every battlefield
with her uniformed masters, and who takes an immediate liking to
Chesterfield, to the point that she accompanies him on a dangerous
scouting mission …
