The enemy's advance was at first directed against what was thought to be the weakest part of the Third Army, namely its right flank, which had sent a number of reinforcements to the Carpathian wing; but the alertness of the Russian general on this side produced an alteration in the plan, and the attack was diverted to the next army corps eastwards. This corps contained regiments which had had heavy losses in the previous hill-fighting. A gap was forced between the two army corps; and the right flank of the threatened corps (the R Regiment) was crushed by the pounding fire which I have described under May 3. The regiment retreated in good spirit, but with the heaviest losses, the O Regiment, holding its ground to the end, retired with its colonel and some 300 men: the Z Regiment was severely cut up. In all this fighting practically every infantry attack of the enemy was beaten back. The next day the impact fell mainly on the troops which I described on May 4. They held their ground to the evening and then executed an orderly retreat, coming into line with the broken forces to the right of them. But on both days a tremendous cannonade was directed on the division still further eastward, with the result that some regiments suffered terribly. The next day a fresh corps, the Caucasians, one of the most famous in the Russian army, had arrived and went forward boldly to the attack on the flank of the enemy's advance. The prisoners cannot speak too highly of the courage of this corps; and it did succeed in stemming the tide, with such effect that the broken army corps to its right had in two days reformed and come again into position. But it did not get as far as the enemy's heavy artillery, and retired fighting rearguard actions--not much further than the point from which it had started. I have explained that the whole advance of the enemy was a counter-stroke to the Russian advance over the Carpathians further eastwards. The right wing of that advance was now outflanked and had to retire. Half of this corps succeeded in rectifying its positions without serious loss; but the other division had the greatest difficulty in fighting its way through, and lost heavily. Meanwhile the enemy's attack was extended also westwards, including the area against which it had been originally directed. Here the cannonade was furious and the trenches were in many parts wiped out, all approach to them of reinforcements from the rear being made almost impossible. But here, too, practically all hostile infantry attacks were repulsed with heavy loss. Ultimately a retreat was ordered by the Russians on this side. Results are indefinite unless they bring one side or the other to a definite line of defence.
