May 6, 1916, brought a slightly new variation in fighting. Russian torpedo boats appeared in the Gulf of Riga, off the west coast, and bombarded, without success, the two towns of Rojen and Margrafen. Artillery fire of considerable violence marked the next day, May 7, 1916. Russian batteries before Dvinsk caused a fire at Ill, the little town just northwest of Dvinsk on the Dvinsk-Ponevesh railway, and so well was this bombardment maintained that the Germans were unable to extinguish the conflagration before it had reached some of their munition depots. In the early morning hours very violent gunfire was directed south of Illuxt. But an infantry attack, for which this bombardment was to act as preparation, failed. Other bombardments were directed against Lake Ilsen and the sector north of it, and against the region south of the village of Vishnieff on the Beresina River. Mining operations of considerable extent were carried out that night near the village of Novo Selki, south of the town of Krevo. On May 8, 1916, artillery fire again roared along the Dvina front, especially against the Uxkull bridgehead. An attack in force was made by German troops against the village of Peraplianka north of Smorgon on the Viliya May 9, 1916. After considerable artillery preparation the Germans rushed up against the Russian barbed-wire obstacles. There, however, they were stopped by concentrated artillery and rifle fire and, after heavy losses, had to withdraw. A Russian attack of a similar nature south of Garbunovka was not any more successful. In the Pripet Marshes, too, artillery operations had by now become possible again and the Russian positions west of the village of Pleshichitsa, southeast of Pinsk, were subjected to a violent bombardment. Throughout the balance of May not a day passed during which guns of all calibers did not maintain a violent bombardment at many points along the entire front. Especially frequent and severe was the gunfire which the Germans directed against the Dvina sector of the Russian positions. But, just as in the past weeks, the result, though not at all negligible as far as the damage inflicted on men, material, and fortifications was concerned, was practically nil in regard to any change in the location of the front.
