The Warsaw salient was now in great peril. Spears had been planted against its breast in three different directions. At the apex a spearhead was but fifteen miles away; another was only ten miles from the southern railway, and a third was but twenty miles from the northern railway. The fortified line of the Narev had been broken through, and the salient was doomed. Once more the Grand Duke had to make a decision upon which hung the fate of the Russian armies. Should he try by means of the great Polish triangle of fortresses--Novo Georgievsk, Ivangorod, Brest Litovski--to hold the salient, or should he sacrifice Poland and fall back to the east? The second course was by far the more difficult. To withdraw his armies along the three railways left to him, while the spearheads were closing in hour by hour, and any day two of the three roads of escape might be lost, was a most perilous task. His wornout troops would have to hold the sides of the salient for some weeks while the main body retired. If the sides were forced in, it was more than likely that his armies would be utterly overwhelmed. It seemed easier to hold on to the fortresses, and hope that in some way or other the enemy might be checked. The Grand Duke refused to take any risks; he chose the more difficult task. He determined to withdraw his armies from Poland altogether, and fall back eastward and ever eastward, until his forces could be properly fed with munitions and were ready to make a stand. It was a great resolve, and few commanders would have dared to make it. Probably no other army could have made such a retirement without losing heart altogether, and hopelessly breaking down. * * * * * The last days of July saw strange scenes in Warsaw. The whole city was stripped of everything that might be useful to the enemy. The great factories were dismantled, and their plant sent eastward. Gold from the banks, books and papers from the Government offices, relics and sacred pictures from the churches, bells from the towers, copper from the roofs, wire from the telegraph poles--all were piled on great wagons which followed each other in a long procession across the Vistula bridges. Half a million of the city's inhabitants streamed eastwards in carts and in hackney carriages. Only the Poles and the poorest of the Jews remained.
