The artillery attack against the former was maintained throughout the following two days. German scouting parties which crossed the river Shara, north of the Oginski Canal, on April 22, 1916, were surrounded in the woods adjoining and practically annihilated. On the same day a German squadron of ten aeroplanes bombarded the Russian hangars on the island of Oesel, a small island in the Baltic across the entrance to the Gulf of Riga. As if both sides had agreed to observe the Easter holidays, a lull set in during the next four or five days. Only occasional unimportant local attacks and artillery duels were reported. Aeroplanes were the only branch of the two armies which showed any marked activity. Dvinsk was visited repeatedly by German machines and extensively bombarded. On April 26, 1916, a German airship dropped bombs on the railway station at Duna-Muende, at the mouth of the Dvina, and caused considerable damage. Other railway stations and warehouses at various points, as well as a number of Russian flying depots, were attacked on April 27, 1916. The end of April, 1916, brought one more important action, the most important, indeed, which had occurred anywhere on the eastern front since the Russian offensive of the latter half of March, 1916. On April 28, 1916, at dawn, German artillery began a very violent bombardment of the Russian positions south of Lake Narotch. There, between the village of Stavarotche and the extensive private estate of Stakhovtsy, the Germans had lost a series of important trenches on March 20, 1916, during the early part of the short Russian offensive. Part of these positions had been recaptured a few days later on March 26, 1916. Now, after a considerable artillery preparation, a strong attack was launched with the balance of the lost ground as an objective. Large bodies of German infantry came on against the Russian positions in close formation. They recaptured not only all of the ground lost previously but carried their attack successfully into the Russian trenches beyond. The most fierce hand-to-hand fighting resulted. Losses on both sides were severe, especially so on the part of the Russians, who attempted unsuccessfully during the night following to regain the lost positions by a series of violent counterattacks, executed by large forces of infantry, who, advancing in close formation over difficult ground, were terribly exposed to German machine-gun fire and lost heavily in killed and wounded. The Germans officially claimed to have captured as a result of this operation the remarkably large number of fifty-six officers, 5,600 men, five guns, twenty-eight machine guns and ten trench mortars. During the same day artillery attacks were directed against Schlock on the Gulf of Riga and Boersemnende near Riga, as well as against Smorgon, south of the Lake district.
