On June 18, 1916, further progress and additional large captures of Austro-Hungarian and German prisoners were reported by the Russian armies fighting in Volhynia, Galicia, and the Bukowina. However, both the amount of ground gained and the number of prisoners taken were very much slighter than had been the case during the earlier part of the Russian offensive. This was due to the fact that the armies of the Central Powers had received strong reenforcements and had apparently succeeded in strengthening their new positions and in stiffening their resistance. Powerful counterattacks were launched at many points. One of these, according to the Russian official statement, was of special vigor. It was directed against General Brussilov's armies which were attempting to advance toward Lemberg, in the region of the village of Rogovitz to the southwest of Lokatchi, about four miles to the south of the main road from Lutsk to Vladimir-Volynski. There the Austro-Hungarian forces in large numbers attacked in massed formation and succeeded in breaking through the Russian front, capturing three guns after all the men and officers in charge of them had been killed. The Russians, however, brought up strong reenforcements and made it necessary for the Austro-Hungarians to withdraw, capturing at the same time some hundred prisoners, one cannon, and two machine guns. At another point of this sector in the region of Korytynitzky, southeast of Svinioukhi, a Russian regiment, strongly supported by machine-gun batteries, inflicted heavy losses on the Austro-Hungarian troops and captured four officers, a hundred soldiers, and four machine guns. South of this region, just to the east of Borohoff, a desperate fight developed for the possession of a dense wood near the village of Bojeff, which, after the most furious resistance, had to be cleared finally by the Austro-Hungarian forces, which, during this engagement, suffered large losses in killed and wounded, and furthermore lost one thousand prisoners and four machine guns. At still another point on this part of the front, just south of Radziviloff, a Russian attack was resisted most vigorously and heavy losses were inflicted on the attacking regiments. Here, as well as in other places, the Austro-Hungarian-German forces employed all possible means to stem the Russian onrush, and a large part of the losses suffered by General Brussilov's regiments was due to the extensive use of liquid fire.
