The stereotype of the Poilu was of bravery and endurance, but not always of unquestioning obedience. At the disastrous Chemin des Dames offensive of 1917 under General Robert Nivelle, they were said to have gone into no man's land making baa'ing noises—a collective bit of gallows humour signalling the idea that they were being sent as lambs to the slaughter. Outstanding for its mixture of horror and heroism, this spectacle proved a sobering one. As the news of it spread, the French high command soon found itself coping with a widespread mutiny. A minor revolution was averted only with the promise of an end to the costly offensive.
