In February 1946, after WW-II had ended, nearly 20,000 ratings of the Royal Indian Navy (RIN) posted in 78 ships in different Indian ports rebelled against their masters. Their rebellion was only partly against their officers; it was just as much against the occupation of India by the alien British rulers. It was part of a saga of India nationalism. The book admirably tells this story and thus fills a big gap in the popular imagination of the freedom struggle.
