The snowfall was unprecedented and had cut off all the popular tourist destination routes in Lachung Valley in a span of two hours.
The continuous snowfall for two hours had taken the temperature below minus 10 degree Celsius.
However, the Army personnel reached out to the stranded tourists in just four hours by risking their lives amidst heavy snowfall and saved the lives of the tourists at sub-zero temperatures.
The tourists, most of whom were from West Bengal, were provided food, shelter and medical care at the Army camps, said media reports.
A lady tourist was given immediate medical care among many others who complained of dizziness, breathlessness and other high altitude related symptoms.
The tourists were grateful to the Indian Army for their help.
They are supposed to be brought down to Gangtok on Thursday.
