Today's OED antedating: "body blow"

Body blow, figurative, slang, a debilitating shock, ex boxing assault to torso, reputed to cause cumulative damage ("body," n., sec 29 (b) (a), first use cited 1908): Book titled Forty Modern Fables, by George Ade, 1901, p 16: "'If I had lived here for twenty-seven Years I would not be afraid to Die, either. In fact, I think I'd be downright Anxious to Die.' But the crafty Biologist did not release this Body Blow until he was good and sure that the Train had started to move."
