As a case in point, I was generally very ignorant of what was taking place in other areas of the war. German newspapers were pretty plentiful in all our camps; but very few French or British found their way into our hands. German accounts were not reliable in my opinion, but some of their statements could hardly be altogether untrue. The news of the loss by submarine torpedoes of the three battleships, _Aboukir_, _Hogue_ and _Cressy_, perturbed me greatly. The reports in German newspapers, combined with other rumours which reached us, made it clear enough that the British Navy had met with a great disaster, though I was compelled to rely on the translations of Russian comrades of these German reports. The Russian cavalry made some attempts to penetrate East Prussia, and get at the trains which were conveying troops from Koenigsberg southwards; but none of these attempts were successful so far as I have heard. A few isolated patrols got a long way into Prussia, but, I think, in no case did they succeed in wrecking a train. For a time I was out of action, though I tried to reach the scenes of fighting I heard was in progress. The East Prussian frontier is a very difficult country for military operations, especially those of an offensive description. The marsh lands are very extensive, and there are numerous lakes and ponds which greatly aid the defending force, while much hindering those engaged in the attack. Lakes and marshes enable an army on the defensive greatly to extend its front; which those engaged in the assault cannot do without at any rate incurring great risks. The Germans often threw up batteries between two lakes, or a lake and a marsh situated near each other. As these could be approached only on a narrow neck of land, they could be defended by a mere handful of men, while the attacking force was not only compelled to advance a strong party, but had, also, to keep others in hand to prevent being outflanked. Something of this kind of fighting I saw; but much of it occurred further south, near the Vistula river, in a district where I was not engaged at the time it took place.
