The 21st Discworld novel.
Discworld goes to war, with armies of sardines, warriors, fishermen, squid and at least one very camp follower.
As two armies march, Commander Vimes of Ankh-Morpork City Watch faces unpleasant foes who are out to get him . . . and that's just the people on his side. The enemy might be even worse.
'Jingo', the 21st in Terry Pratchett's phenomenally successful Discworld series, makes the World Cup look like a friendly five-a-side.
