`` Do you lie down , Pierre . At two o'clock I will call you , and you shall take my place . '' Pierre went out , but before lying down he again went quietly downstairs and , with a wet cloth , entirely erased the mark from the door ; and then , placing his sword and his pistols ready at hand , lay down on his pallet . At one o'clock Philip aroused him . `` There is something unusual going on , Pierre . I can see a light in the sky , as of many torches ; and can hear a confused sound , as of the murmur of men . I will sally out and see what it is . ''
