Hunger became a serious issue in the Dutch cities. When it was no longer possible to send food parcels to the camps, Wijsmuller, as a member of an interconfessional group, organized the evacuation of 6,649 famished children[1] from Amsterdam across the IJsselmeer to the countryside. The children were able to recuperate there.[citation needed]
