The Americans do not appear to have been duped.

I wonder if he was influenced by the opinion that most of the survivors were Italian POWs of the British. I could find nothing on that aspect other than the Brits noted many survivors were POWs. when they informed the Americans.

So, bad call on the US part.

The Americans returned for a second attack. That was absolutely all on them. But the Brits are the ones who notified the US that the Laconia was sunk by submarine and omitted the information that Hartenstein had radioed in the clear that he was picking up survivors and would not attack any vessels that came to their aid.
