What was the code name for army action in the Golden Temple that was carried out by the Indian Government in 1984?

Operation Blue Star

Soon, the leadership of the movement passed from the moderate Akalis to the extremist elements and took the form of armed insurgency. These militants made their headquarters inside the Sikh holy shrine, the Golden Temple in Amritsar, and turned it into an armed fortress. In June 1984, the Government of India carried out ‘Operation Blue Star’, code name for army action in the Golden Temple. In this operation, the Government could successfully flush out the militants, but it also damaged the historic temple and deeply hurt the sentiments of the Sikhs. A large proportion of Sikhs in India and abroad saw the military operation as an attack on their faith and this gave further impetus to militant and extremist groups.
