overnight a steady stream of bad news had flowed into the city , though at least these pieces of intelligence had been largely expected , if not so soon : saxe-weimar 's detachment caught by marshal davout , every last man of ten thousand killed or taken prisoner ; bernadotte already at magdeburg , cutting hohenlohe off ; the elbe crossings falling into french hands , not a single bridge destroyed ; bonaparte himself already on the road to berlin , and when temeraire rose up into the air , they could see , not very distant , the smoke and dust of the oncoming army : marching , marching , with a cloud of dragons overhead .
