New Delhi, Nov.12 Australia's First Lady and wife of Prime Minister Kevin Rudd, Therese Rein, on Thursday became the first head of government's wife to lay a wreath at the India Gate memorial to the "Unknown Soldier".

The memorial, which is also known as the "Amar Jawan Jyoti", is dedicated to the men and women soldiers who laid down their lives during the First World War (1914-1918). The names of 13,500 armed forces personnel are inscribed on the memorial.

Both Rudd and Rein jointly laid wreath at the memorial, as that is the tradition back at home in Australia.

From the Australian point of view, the memorial is significant in that it contains the name of one Australian officer - Sister Latetia - who died of enteric disease on November 11, 1916.

Born in the Australian state of Victoria, Sister Latetia was a member of the Australian Nursing Service and was attached to General Hospital Number Two during the war. (ANI)
