Elizabeth II - Wikipedia
In September 1939, Britain entered the
Second World War.
Lord Hailsham[24] suggested that the two princesses should be
evacuated to Canada to avoid the frequent
aerial bombing. This was rejected by Elizabeth's mother, who declared, "The children won't go without me. I won't leave without the King. And the King will never leave."
[25] Princesses Elizabeth and Margaret stayed at
Balmoral Castle, Scotland, until Christmas 1939, when they moved to
Sandringham House, Norfolk.
[26] From February to May 1940, they lived at
Royal Lodge, Windsor, until moving to
Windsor Castle, where they lived for most of the next five years.
[27] At Windsor, the princesses staged
pantomimes at Christmas in aid of the Queen's Wool Fund, which bought yarn to knit into military garments.
[28] In 1940, the 14-year-old Elizabeth made her first radio broadcast during the
BBC's
Children's Hour, addressing other children who had been evacuated from the cities.
[29] She stated: "We are trying to do all we can to help our gallant sailors, soldiers and airmen, and we are trying, too, to bear our share of the danger and sadness of war. We know, every one of us, that in the end all will be well."
[29]
In 1943, Elizabeth undertook her first solo public appearance on a visit to the
Grenadier Guards, of which she had been appointed colonel the previous year.
[30] As she approached her 18th birthday, parliament changed the law so she could act as one of five
Counsellors of Statein the event of her father's incapacity or absence abroad, such as his visit to Italy in July 1944.
[31] In February 1945, she was appointed as an honorary second
subaltern in the
Auxiliary Territorial Service with the
service number of 230873.
[32] She trained as a driver and mechanic and was given the rank of honorary junior commander five months later.

Victory in Europe Day
At the end of the war in Europe, on
Victory in Europe Day, Princesses Elizabeth and Margaret mingled anonymously with the celebratory crowds in the streets of London. Elizabeth later said in a rare interview, "We asked my parents if we could go out and see for ourselves. I remember we were terrified of being recognised ... I remember lines of unknown people linking arms and walking down
Whitehall, all of us just swept along on a tide of happiness and relief."
