The lesson we learn from reasons for Failure of Quit India Movement 1942

People were left without leaders, and in the absence of leadership and proper organisation, people could not stand for a long time before the mighty strength of an imperial power of Government.
The movement did not get support from the Muslim League and the Communists, which also deterred the movement.
According to Jayaprakash Narain, the movement failed due to a lack of coordination among the Congress people agitating in different parts of the country.
There was also no clear-cut programme of action.
Another weakness that can be seen is that it was limited only to peasants, students, and the lower middle class.
