I've been trying to find a proof for Fermat's last theorem with exponent n = 3 using unique factorization in $\mathbb{Z}[w]$ where $w$ is a primitive third root of unity ( solution of $x^3$ - 1 ). I presume it's in Edwards book on Fermat's Last Theorem but I don't have access to it unfortunately.

Would anyone know where I could find a proof online or be able to provide one? Any help would be appreciated thanks.
