Danish Jews being transported to Sweden
From October 1943 the boat Gerda III of the Danish Lighthouse and Buoy Service was used to ferry Jewish refugees from German-occupied Denmark to neutral Sweden. With a group of some ten refugees on board for each trip, the vessel set out for her official lighthouse duties before detouring to the coast of Sweden. Between the lighthouse manager's daughter Henny Sinding Sundø and Gerda III's crew (Skipper Otto Andersen, John Hansen, Gerhardt Steffensen, and Einar Tønnesen), they together ferried approximately 300 Jews to safety.
