The Bluecoats Tome 5
Rumberley

Left behind with the wounded, Blutch and Chesterfield must defend their fellow Union soldiers against Southern troops... and civilians ! Alter an even bloodier battle than usual, the Union Army is out of men. But so are the Confederates, and General Alexander decides to retreat and corne back with reinforcements before the enemy can do the saure. To move faster, he leaves his wounded, including Stark and Chesterfield, behind in the nearby town of Rumberley, in the care of its inhabitants and Corporal Blutch.
But Rumberley's a Rebel village... "The slapstick comedy of errors is done really well, the wordplay is clever and silly at the same time. And add in those clever touches and repeated motifs and it gets better." Richard Bruton, Forbidden Planet International Blog
