In the first few months how many children were registered?

The children were sent mainly to the four Dominion countries, Canada 1,532 (in nine parties), Australia 577 (three parties), New Zealand 202 (two parties), and South Africa 353 (two parties), and 838 to the USA under the United States Committee for the Care of European Children programme. In the first few months over 211,000 children[2] were registered with the scheme. A further 24,000 children had been approved for sailing in that time and over 1,000 volunteer escorts, including doctors and nurses, enrolled. It was planned as a temporary exile for the children, to return home to their families when conditions permitted.
