Do naval vessels rescue enemy seamen?

[LSLGuy]

I’ll cite another thread from a couple days ago that touches on very similar points to this one, and especially to the comments by @Dissonance just above.

The OP might find this worth reading:

Would submarines ever help a ship in trouble?

Like a passenger ship or actually anything non-military that sends a distress signal? Or even one person in a lost sailboat? Have subs ever helped in a passenger ship rescue? Do they just tell someone else and let them do something? Or do they just ignore anything because it would reveal where they are?
