At daybreak heavy artillery fire was poured upon the Russians from the German position to the north of Rossiennie, while at the same time the German infantry fell upon the Russian flank and rolled it up, with the result that the Russians were compelled to recross the Dubissa. In the crossing numerous wounded were drowned in the river. The Germans took 2,500 prisoners and fifteen machine guns. Similar counterattacks were delivered by the Germans on the River Wenta. Then, on the 5th of June, 1915, a general offensive was entered upon by the whole German line on orders from the General Staff, which carried it beyond the Dubissa, and after heavy fighting finally secured for the Germans the Windawski Canal, which they had had to relinquish before. Their troops now slowly pushed their way back toward Shavli until the city came within reach of their heavy guns, and took Kuze, twelve kilometers to the northwest of Shavli on the railway. On the 14th of June, 1915, this series of operations came to a temporary halt. German official reports pointed to the fact that among 14,000 prisoners which they had taken there were only a few officers, and that with these not a single cannon was captured. They regarded it as showing that the Russians were getting very cautious in the use of their artillery and were short of officers. * * * * * CHAPTER XLIII RUSSIAN OFFENSIVE FROM KOVNO--FOREST BATTLES IN MAY AND JUNE Offensives on a large scale such as that which had been prevented by the "Winter Battle of the Mazurian Lakes" were not attempted by the Russians on their northern wing after the short counterattack that had pushed their lines into the Mlawa angle in the corner of the Vistula and the Prussian boundary beyond Przasnysz, to the east of Thorn. They virtually remained in their strongly fortified positions along the Narew, the Bobr, and the Niemen, except for the sending out of occasional attacking columns against the German lines lying opposite to them.
