During World War II, Princess Andrew was in the difficult situation of having sons-in-law fighting on the German side and a son in the British Royal Navy. Her cousin, Prince Victor zu Erbach-Schönberg, was the German ambassador in Greece until the occupation of Athens by Axis forces in April 1941. She and her sister-in-law, Princess Nicholas of Greece, lived in Athens for the duration of the war, while most of the Greek royal family remained in exile in South Africa. She moved out of her small flat and into her brother-in-law George's three-storey house in the centre of Athens. She worked for the Red Cross, helped organise soup kitchens for the starving populace and flew to Sweden to bring back medical supplies on the pretext of visiting her sister, Louise, who was married to the Crown Prince. She organised two shelters for orphaned and lost children, and a nursing circuit for poor neighbourhoods.
