Maybe it's the "ignorant armies" that made me think this was some work that evolved out of modern warfare when I first read it many years ago, but of course, there were no planes dropping bombs from the sky in 1867. The beauty of "Dover Beach" has always been its immediacy and relevance, Yes, I know, a poem doesn't have to be relevant in any historical sense, but the emotions the poet expresses here haven't changed much in a century and a half...and probably won't anytime soon.
