October and November 1962 were unforgettable months for those who lived through that era. On October 20, the Chinese crossed the Namka Chu and disseminated a brigade of the Indian Army. A month later, on November 19-20, they crossed the high mountain passes and came to the foothills of ranges on the north bank of the Brahmaputra river. It was the gravest moment in India’s post-Independence history.
