The British Once Built a 1,100-Mile Hedge Through the Middle of India
"On the Salt March: The Historiography of Mahatma Gandhi's March to Dandi" by Thomas Weber is very well written, detailed account on both the salt tax and the logistics of the march itself. I read it 4 years ago at a library in Lakshadweep. I still find it hard to imagine, that we lived under these extremely stupid laws made just to maximize British profit and create monopolies by destroying free markets. And, I find it so sad that the first independent government chose to double down on the control on the economy rather than just open it all up.
