Counterattack
A counterattack was an attack that was made in response to an attack by an enemy or opponent.
In 2371, Elim Garak had apparently revised his opinion at least somewhat, when choosing to paraphrase a passage from the Julius Caesar play to Enabran Tain in effort to explain the failure of a joint Obsidian Order-Tal Shiar task force to anticipate the Dominion surprise counter-attack that subsequently destroyed it: "I'm afraid the fault, dear Tain, is not in our stars... but in ourselves. Something I learned from Doctor Bashir." (DS9: "The Die is Cast")
