His officer Mark Antony prevented Ptolemy XII from massacring the inhabitants of Pelousion for their defiance, and rescued the body of Archelaos (Berenice's husband) after he was killed in battle. Although Antony said years later that it was then that he fell in love with Cleopatra, their affair did not begin until 41 BC. Ptolemy XII made Cleopatra his regent and joint ruler in 52 BC, naming her and his son (Ptolemy XIII) joint successors in his will and testament.
