Faithless Nelly Gray
Pun on 'arms'
Hood plays on 'arms' meaning both weapons and limbs. Ben 'laid down his arms' literally—he can no longer hold a gun. The joke collapses the two meanings.
Military unit as body part
The 'Forty-second Foot' is Ben's regiment. By saying he leaves his leg 'and the Forty-second Foot,' he's making the unit itself a casualty of war—it loses its soldier.
Wooden members pun
Ben calls his prosthetic legs 'wooden members'—a pun on 'members' as both body parts and parliamentary representatives. He's sardonically suggesting politicians are equally artificial.
Nelly's cruelty escalates
She doesn't just reject him—she 'began to take them off.' Hood moves from rejection to active removal of his prosthetics, making her cruelty physical and grotesque.
Uniform/love wordplay
'Uniform' means both military dress and consistency. Ben accuses her love of being inconsistent—she loved the uniform (the soldier), not the man beneath it.
Badajos battle reference
[CONTEXT] Badajos was a brutal 1812 Peninsular War siege. Hood uses a real battle to ground Ben's sacrifice in actual military history, not abstraction.
Suicide method and wordplay
Ben 'Enlisted in the Line'—military service becomes a euphemism for hanging ('the Line' as a noose). Hood hides suicide language inside military vocabulary.
Suicide logic: 'off his legs'
Hood's final pun: because Ben's prosthetic legs are removable, 'he soon was off his legs'—a darkly literal joke about a man hanging himself. The wooden legs enable the suicide.
