"The Charge of the Light Brigade" was a poem by the human poet Alfred, Lord Tennyson, describing a disastrous British Army cavalry charge at the Battle of Balaclava during the Crimean War. In 2374, Miles O'Brien and Julian Bashir quoted the third verse of the poem before engaging Dominion and Cardassian Union vessels during Operation Return. Elim Garak asked them how the poem ended and O'Brien replied, "You don't want to know." (DS9 episode & novelization: Sacrifice of Angels)
