Coup de grâce

A coup de grâce (/ˌk də ˈɡrɑːs/; French: [ku ɡʁɑs] lit.'blow of mercy') is an act of mercy killing in which a mortally wounded person or animal is fatally struck with a melee weapon or shot with a projectile to kill them quickly and end their suffering, with or without their consent. With animals, it may be done by hunters to animals they have shot which have fallen, but which are still alive or by veterinarians to seriously injured animals which are dying or in pain. With humans, it may be done by a firing squad after a volley of shots at a condemned prisoner, or by soldiers in wartime who have captured a seriously wounded enemy soldier, although this may be a war crime.
