I have successfully recovered the Black Pearl five times now, but it took three tries before I received credit for it!

A group of players entering as a crew will not receive credit for winning the battle. A couple of friends and I took turns starting the battle alone, and then the others teleported to the person who started the battle. Done that way, we each received credit for completing the quest.

As my two friends had pirates which had already recovered the Black Pearl, they used their bigger pirates when they were not the person starting the battle. Unfortunately, we do not know if one of the pirates who teleport in would be given credit as well if they had not yet completed that quest.
