Gandhi sent an ultimatum in the form of a polite letter to the viceroy of India, Lord Irwin, on 2 March. A young left wing British Quaker by the name of Reg Reynolds delivered the letter. Gandhi condemned British rule in the letter, describing it as "a curse" that "has impoverished the dumb millions by a system of progressive exploitation and by a ruinously expensive military and civil administration... It has reduced us politically to serfdom." Gandhi also mentioned in the letter that the viceroy received a salary "over five thousand times India's average income. British violence, Gandhi promised, was going to be defeated by Indian non-violence.
This (Gandhi's letter to the viceroy of India) was highlighted by the famous Salt March to Dandi from 12 March to 6 April, where, together with 78 volunteers, he marched 388 kilometres (241 mi) from Ahmedabad to Dandi, Gujarat to make salt himself, with the declared intention of breaking the salt laws. Thousands of Indians joined him on this march to the sea. The march took 25 days to cover 240 miles with Gandhi speaking to often huge crowds along the way.
