Use "mincing machine" in a sentence
"The opening of the battle had been full of excitement and motion, yet it was not those heart-stirring moments that Sharpe remembered when he woke sweating in the night, but rather that inhuman mincing machine of the French artillery; the lurid flickering of its massive cannon flames in the smoke bank, the pathetic cries of the dying, the thunder of the roundshot in the overheated air, the violence of the soil spewed up by the striking shots and the stomach-emptying terror of standing under the unending cannonade that had punched and crashed and pounded down the bravest man's endurance."
"In 1916, Falkenhayn's mincing machine had been turned off when another month would have destroyed the whole French Army."
