What was the name of the amazon warrior who was killed by Achilles?

I submit that it was Achilles that was killed by the Amazon queen, Penthesilea, ruler of the Thermodontine Amazons, rather than the other way around, according to the research of Carla Osborne. PENTHESILEA, responded to a call for help from the besieged queen of Troy. The Amazons temporarily freed the city, and Penthesilea killed Achilles, leader of the Myrmidonian Greeks. Penthesilea, in turn, was killed by treachery, stabbed in the back by one of the priests of Apollo who had betrayed the city. Contrary to popular belief, Penthesilea was not part of last flair of greatness from a dying nation (the Amazons). Homeric Troy fell around 1200 BCE, six centuries before the official political demise of the Northern Amazon Nation. What Penthesilea probably represents is the beginning of the retreat of Goddess worshipping peoples in Asia Minor in the face of continuing violence from invaders.

An realistic viewpoint:

The stories surrounding the Trojan War era are legends, of which there were many different versions, initially sung by the strolling bards, each with their own several versions. When these began to be written down a few hundred years later, even the written versions varied between each other. What we have today are stories, not history. The name of the Amazon killed by Achilles in these tales is Penthesilea.
