Cleopatra's Death
In the page "Who was Cleopatra?", it says specifically how Cleopatra died. Here is just a recap:
They fled back to Egypt; where Antony soon returned to the battlefield. Soon after he rejoined the army, he was falsely informed Cleopatra had died. In response to the news, Antony stabbed himself in the chest with his sword. When Cleopatra heard that he had died, she ordered an Egyptian cobra. She let it bite her in the chest, causing her to die as well.
