Read it through once

The battle of Waterloo was fought on the 18th of June, 1815. I do not state this fact as a reminder to the reader, but as news to him. For a forgotten fact is news when it comes again. Writers of books have the fashion of whizzing by vast and renowned historical events with the remark, “The details of this tremendous episode are too familiar to the reader to need repeating here.” They know that that is not true. It is a low kind of flattery. They know that the reader has forgotten every detail of it, and that nothing of the tremendous event is left in his mind but a vague and formless luminous smudge. Aside from the desire to flatter the reader, they have another reason for making the remark-two reasons, indeed. They do not remember the details themselves, and do not want the trouble of hunting them up and copying them out; also, they are afraid that if they search them out and print them they will be scoffed at by the book-reviewers for retelling those worn old things which are familiar to everybody. They should not mind the reviewer's jeer; he doesn't remember any of the worn old things until the book which he is reviewing has retold them to him.
