Where did the French troops refuse to fight in World War 1?

During World War I, French troops famously refused to fight in the Battle of Verdun in 1916 due to the extreme conditions and heavy casualties. This reluctance was part of a broader context of mutinies and discontent among French soldiers, particularly following the 1917 Nivelle Offensive, where many felt disillusioned and demoralized by the leadership and the war's stalemate. The refusal to fight highlighted the growing fatigue and resistance among the troops amidst the grueling trench warfare.
