Warsaw had fallen, and Ivangorod, and the centre of the German and Austro-Hungarian armies, sweeping across eastern Europe like beaters across a prairie, was now before Brest-Litovsk. This was the apex of this central triangle of Russian forts, a city and a rail-road centre as well as a fortress, and the last strongly fortified place on the direct road to Moscow. It seemed as if the Russians must make a stand here, and even though we were four or five days getting there, the heavy artillery was not yet up, and there might still be time.
