Last year I had obtained a print of the photo of Mahatma Gandhi picking up salt at Dandi. This was presented to my alma mater, the Rashtriya Indian Military College, Dehradun, to commemorate the 75th anniversary of the Dandi March. The great Salt March is an event that shook the British Empire.
Gandhi's articles, notes, letters and speeches from the period of the Dandi March (12 March - 6 April 1930) are to be found in Vols. 48 and 49 of The Collected Works of Mahatma Gandhi.
