It was natural that she should feel grateful to Caesar for his efforts and sacrifices in her behalf, and that she should be inclined to favor the cause of his friends.

Accordingly, instead of sending troops to aid Brutus and Cassius, as they had desired her to do, she immediately fitted out an expedition to proceed to the coast of Asia, with a view of rendering all the aid in her power to Antony's cause.
Cassius, on his part, finding that Cleopatra was determined on joining his enemies, immediately resolved on proceeding at once to Egypt and taking possession of the country.

He also stationed a military force at Taenarus, the southern promontory of Greece, to watch for and intercept the fleet of Cleopatra as soon as it should appear on the European shores.

All these plans, however--both those which Cleopatra formed against Cassius, and those which Cassius formed against her--failed of accomplishment.

Cleopatra's fleet encountered a terrible storm, which dispersed and destroyed it.
