The lesson I took away from the campaign was that in the end, we had no alternative to armed and violent resistance. Over and over again, we had used all the non-violent weapons in our arsenal - speeches, deputations, threats, marches, strikes, stay-aways, voluntary imprisonment - all to no avail, for whatever we did was met by an iron hand. A freedom fighter learns the hard way that it is the oppressor who defines the nature of the struggle, and the oppressed is left no recourse but to use methods that mirror those of the oppressor. At a certain point, one can only fight with fire.
