Princess Elizabeth was called on to perform many public duties for the royal house as she grew older. On Oct. 13, 1940, the 14-year-old made her broadcasting debut during World War II on the "Children's Hour," a BBC radio program.
She spoke to the nation of England, giving a three-minute speech to the British girls and boys who were evacuated overseas to find new wartime homes in Canada, Australia, New Zealand, South Africa, and the United States.
"[W]e children at home are full of cheerfulness and courage," Elizabeth told the listening audience. "We are trying to do all we can to help our gallant sailors, soldiers and airmen, and we are trying, too, to bear our own share of the danger and sadness of war. We know, every one of us, that in the end, all will be well, for God will care for us and give us victory and peace. And when peace comes, remember it will be for us, the children of today, to make the world of tomorrow a better and happier place."
Her sister, Princess Margaret, joined her to say goodnight to listeners.
