I once called my Dad out about Chinese nationalists setting bombs on ships in the 60s. He reckoned his ship had come to the rescue of one where they'd found a bomb and the command crew had posed with it for a photo and it had gone off, killing or wounding all the crew capable of actually navigating the ship.
No mention on Wikipedia of these terrorist activities, nothing in the history I could find online. He was a bit of a tall tale teller so I called him out on it.
He was quite upset and ended up showing me his ship log book. With the ship name and the rough date, I actually found two news articles that had been scanned by Google scholar conforming that it had really happened.
I bet there's a lot we don't know that happened behind the iron curtain, I wouldn't doubt this just because you can't easily find any references with a quick Google.
If you want the rest of how they saved the ship, they tried to get a junior officer over in a sort of swing. If they'd have succeeded they'd have actually all been entitled to a salvage payment. But it was too rough so in the end they just got the other ship to follow them back to port.
When the pilot came out to dock the ship, he found another bomb.
