The Amar Jawan Jyoti at India Gate in New Delhi was merged with the eternal flame at the National War Memorial on Friday.
In a short ceremony, a part of the Amar Jawan Jyoti flame was taken and merged with the flame at the NWM, which is 400 metres away on the other side of India Gate.
Chief of Integrated Defence Staff Air Marshal B R Krishna presided over the ceremony.
The Amar Jawan Jyoti was constructed as a memorial for Indian soldiers who were killed in action in the 1971 Indo-Pak war, which India won, leading to the creation of Bangladesh.
It was inaugurated by the then prime minister, Indira Gandhi, on January 26, 1972.
Prime Minister Narendra Modi had on February 25, 2019, inaugurated the NWM, where names of 25,942 soldiers have been inscribed in golden letters on granite tablets.
