George McDonald Fraser's hilarious historical fiction series about Harry Flashman.
Flashman is a Victorian cavalry officer antihero "who runs from danger or hides cowering in fear, betrays or abandons acquaintances at the slightest incentive, bullies and beats servants with gusto, beds every available woman, carries off any loot he can grab, and gambles and boozes enthusiastically. Nevertheless, through a combination of luck and cunning, he usually ends each volume acclaimed as a hero."
