Probal Dasgupta is a former infantryman with the Gorka Regiment who traced the battles between India and China on the Sikkim border in 1967 in a book – Watershed 1967 : India's Forgotten Victory Over China.

Dasgupta spoke with The Quint about the ongoing India-China row and the little know India-China conflict that took place 5 years after India’s defeat in the 1962 war and how it shaped the border management and what it tells us about Chinese military thought process.
