False. The statement claiming that nearly two-thirds of British soldiers went on strike as a result of the failure of the Nivelle Offensive is incorrect. During World War I, the Nivelle Offensive was a major military operation launched by the French army in April 1917. While the offensive did indeed end in failure due to heavy casualties and lack of progress, there is no historical evidence to suggest that nearly two-thirds of British soldiers went on strike as a direct result of this particular military setback.
It is important to verify information from reliable historical sources to ensure accuracy when discussing events from the past. In this case, the claim about British soldiers going on strike after the Nivelle Offensive does not align with known historical accounts of that period.
