After yet another bloody battle, the Union Army organises a recruiting drive during which Blutch attempts to dissuade an obviously too young boy from signing up.

While Chesterfield is tasked with looking after him, Pucky begins to practice his drumming - much to the displeasure of the troops, who are eager to get some rest before the major engagement looming on the horizon.
