I alluded to it but got downvoted by morons who, for some reason, dislike historical facts in a history sub, go figure.

The ship was the SS Drotnighelm iirc, or something like that, and the refugees on it were not the last to be refused entry into the US. The times were very highly charged, and everyone was paranoid, and I guess the decisions seemed sensible at the time, but now looking back with the advantage of the passage of time, we might think that better options should have been found, like the Brits did with the camps.
