Clash by Night is a romantic triangle drama by Clifford Odets which premiered on Broadway in 1941 and was later adapted to film and television. The title derives from Matthew Arnold's poem "Dover Beach" (1867):Ah, love, let us be true To one another! for the world, which seems To lie before us like a land of dreams, So various, so beautiful, so new, Hath really neither joy, nor love, nor light, Nor certitude, nor peace, nor help for pain; And we are here as on a darkling plain Swept with confused alarms of struggle and flight, Where ignorant armies clash by night.
