On April 3, 1917, however, signs began to multiply, indicating that the Germans had decided to begin more extensive operations. On that day they opened a heavy artillery fire against Russian munition depots on the left bank of the river Stokhod, in the region of the Stchervitche-Helenin station, and on the river passages. The fire was delivered partly with chemical shells. Simultaneously the Germans discharged thirteen gas waves from the Helenin-Borovno sector.
Under cover of the artillery fire the Germans took the offensive on the Toboly-Helenin front and pressed back the Russian troops. Part of the Germans succeeded in crossing the Stokhod in the region northeast of Helenin. The Russian left flank detachments, which were defending the munition dumps, found themselves in a serious position owing to the pressure of the Germans and were forced to cross to the right bank of the Stokhod. Some of the Russian detachments suffered heavy losses. After strongly bombarding Russian positions south of Illukst the Germans, attacked and occupied field posts and trenches in the region south of the Poniewesch railway line, but were expelled and driven back by a Russian counterattack.
During the same night the Germans also directed a violent fire with artillery and mine throwers against Russian trenches in the region of the village of Novoselki, south of Krevo. At daybreak a German column in strength of about a company forced its way into first-line trenches near Novoselki, but as the outcome of a counterattack by Russian scouts was dislodged and driven back.
Russian raiding troops attacked the Austrians as they were attempting to fortify positions in the region six miles west of Rafailova. Having penetrated the barbed-wire entanglements the Russian troops occupied three rows of trenches and bayoneted the Austrians. On the remainder of the front rifle firing and reconnoitering operations occurred.
The German success on the Stokhod, according to German reports, developed almost into a rout. It was claimed that almost 10,000 men and officers and fifteen guns and 150 machine guns and mine throwers fell into the hands of the Germans.
On April 5, 1917, after heavy artillery preparation, partly with shells charged with chemicals, the Germans took the offensive and occupied part of the Russian trenches to the east of Plakanen, thirteen miles south of Riga. They were driven out as the result of a Russian counterattack.
On the following day, April 6, 1917, a number of local engagements were reported. North of Brzezany, in the region of Angostoveka and Koniuchy, after artillery preparation, the Germans attacked Russian positions, but were repulsed. Southwest of Brzezany, in the region of Lipnica Dolna, the Russians exploded a mine, destroying some German trenches which the patrols immediately captured. The Russians repulsed all counterattacks at this point and also took prisoners. In the same region they attacked with gas. West of the town of Tomnatik strong German detachments, supported by the fire of artillery, bomb throwers and mine throwers, entered Russian trenches, but were immediately ejected by counterattacks.
Again on April 7 and 8, 1917, the Germans on the Galician front made minor attacks in the Carpathians, in the region west of Dzemdron, in the direction of Marmaroch and Siguet and to the west of the town of Tomnatik. All of these were repulsed, however.
Similar unimportant activities occupied the next few weeks. In the meantime the disorganization of the Russian forces apparently continued to increase. The Germans, however, apparently had decided by this time not to attempt to make any military use of this condition, but to improve the opportunity to come to an understanding with the Russians. Almost daily reports appeared from various sources indicating that a certain amount of fraternizing was going on in many places on the eastern front. Though these reports varied very much, it became quite clear that generally speaking the Russian lines still held. In some places, undoubtedly, Russian detachments of varying size laid down their arms and refused to continue to fight. There were even isolated reports of some military groups having entered into peace negotiations with their opponents. It is almost impossible to sift the truth from these reports. It appears, however, that for some weeks a more or less unofficial truce had been established almost everywhere on the eastern front. The majority of the Russian soldiers at that time undoubtedly were strongly in favor of immediate cessation of hostilities. The Germans, on the other hand, seemed to be acting under orders to treat their opponents with a minimum of severity and to await further political developments before undertaking any important military operations.
The Russians, though of course glad enough to notice this cessation of military activity, apparently were frequently not willing to let the enemy get too close to their lines, even though he pretended to come with friendly intentions. The official Russian report occasionally indicates this, as for instance that for April 15, 1917, which says that "attempts to approach Russian positions at various sectors of our front by small enemy groups, the members of which carried flags in their hands, were discovered. These groups, on coming under our fire, returned rapidly to their trenches."
