Yes there were, infact there were more children that adults

simply put,the kids were hungry,badly affected,confused and some were isolated and victims of war.

Children were evacuated from major ports and cities and sent to the countryside, or abroad, to avoid the risk of them being killed or injured during enemy bombing raids on the ports and cities.
