Who among the following is the author of the book “The Indian Struggle…

Books analysing India's freedom movement, written by a nationalist leader who was himself an active participant, present an eyewitness political history — a narrative and analysis of the movement's events, strategy, and internal debates — grounded in the author's own direct political experience; such a work need not be a personal life-autobiography to be authored by that leader.

“The Indian Struggle 1920–1942” is exactly such a political history: Subhas Chandra Bose wrote it as an account and analysis of the Indian national movement across that period — the Congress's internal strategy debates, the course of the civil disobedience movement, and the rise of more assertive strands within the freedom struggle — drawing on his own active role in these events. It is an expanded edition of his earlier work, “The Indian Struggle 1920–1934”, first published in 1935.
