How did Helen and Siegfried postpone their "relocation"?

In isn't that Helen and Siegfried postponed their relocation, but rather, that circumstances forced the postponement upon them. When the couple and their friends tried to anticipate what would happen next, some of them contemplated suicide over the prospect of such horrific futures. Then Helen and Siegfried learned of a British ship waiting in the port of Ijmuiden to rescue Jews and take them to England. Helen, sadly, was not able to find a taxi willing to take her and Siegfried to the ship and later, they learned that Siegfried's cousins had tried to reach Helen and Siegfried but their telephone wire had been cut. The ship left for England only half filled to capacity.
