The enemy's advance, however, had slackened before it reached the San; and the Russians had had time not only to make good a very spirited retreat but to give their men two days' rest on the eastern side of the river. These two days were invaluable. Large reinforcements were hurried up. In the shortest time entrenchments were thrown up of a kind superior to those held by the Russians during their long occupation of western Galicia, and very much better supported. The earlier ruinous effects of the enemy's heavy artillery were now minimised or even avoided; and the Russian artillery were in much greater force than before. Above all, the men proved, if proof were needed, by the vigour of their resistance and by beating off one German attack after another that the earlier retreat had been due simply to the enemy's technical superiority in artillery, and that even a half-annihilated Russian regiment felt itself to be master as soon as the issue lay with the bayonet. The enemy daily sent aeroplanes to the Russian rear, in one day ten at a time, but in at least five cases these were brought down and in most instances by the fire of musketry and machine guns. In one comparatively weak spot the Russian infantry was rescued by a few timely discharges from our artillery, which sent the close column of Germans running like hares. Attempt after attempt of the enemy to break through in close column failed. At certain points the Germans were able to push home their blow, at others the Russians closed in on their flanks, driving them back to the river and threatening even their success in the centre with serious consequences. At one moment the enemy thought that he was through; but the gap was filled at once from the large Russian reserves. At another he even launched his cavalry through what seemed an empty space, and it looked as if he might find room to develop the favourite German cavalry advance, which has spread such terror among peaceful inhabitants in other parts; but without delay the tide was stemmed by Cossacks and Russian infantry. The struggle is still going on; but one thing is certain--that the Russian resistance east of the San has stopped the forward flow of the German advance. It is a new chapter in the war, and different in essentials from that which preceded it. News of successful resistance or of advance comes from the Russian armies on either flank of our own. _May 27._
