GERMAN INVASION OF COURLAND—CAPTURE OF LIBAU
On the 20th of April, 1915, an announcement was made by the German Great Headquarters which took the Russians and the world in general more or less by surprise. It gave the first glimpse to the public of a group of operations which caused no little speculation in the minds of strategists. It read:
"The advance troops of our forces operating in northwestern Russia yesterday reached on a broad front the railway running from Dunaburg (Dvinsk) to Libau. Thus far the Russian troops present in that region, including also the remnants of those which took part in the raid against Memel, have attempted no serious resistance anywhere. Fighting is now in progress near Shavli."
The advance into Courland here announced had been made by the German troops at high speed. The forces were under the command of General von Lauenstein. They had begun to move early on the 27th of April, in three columns. One of these crossed the Niemen at Schmalleningken, forming the right wing of the troops engaged in the movement. The columns of the left wing broke out of East Prussia at its northernmost point, and moved along the dunes of the Baltic. On the second day of the forward march it was learned by the leaders of the advancing troops that the Russians had hastily left their position at Skawdwile, on the main road from Tilsit to Mitau, to escape being surrounded on their left flank, and had withdrawn to Shavli by way of Heilmy. On the third day the German right column crossed the Windawski Canal under the enemy's fire, and on the afternoon of the 30th of April this column entered Shavli, which had been set on fire by the Russians.
| GERMAN ADVANCE ON RIGA |
The Germans had now crossed at several points the Libau-Dunaburg railway. They were in Telsche and Trischki. Their cavalry pushed ahead at full speed with orders to destroy the railways wherever it found them. On the road to Mitau they captured Russian machine guns, ammunition wagons, and baggage, and broke up the railway tracks to the southwest and northwest of Shavli. The Russians who had been taken by surprise by this movement had apparently only weak forces in Courland, and these had retired while reenforcements were being rushed up by railway. The German infantry, upon the receipt of reports that the Russians were moving up by rail from Kovno on their right flank, was ordered to stop its advance and prepare to hold the Dubissa line, taking up a front running a little east of south. Cavalry moving forward in the center of the German advance on the 3d of May, 1915, got within two kilometers of Mitau, going beyond Grünhof and capturing 2,000 Russians. At Skaisgiry on the day before 1,000 prisoners had been taken, and Janischki and Shagory had been occupied far beyond the Libau-Dunaburg railway. By this time Russian reenforcements were arriving at Mitau in huge numbers. The German cavalry ultimately fell back after indicting all possible damage to the communications in their reach.
The Germans prided themselves a good deal on the marching of their troops in this swift advance. They pointed out that the roads were in extremely bad condition, the bridges for the most destroyed, and the population to a large extent hostile. A military correspondent figured that for a daily march of fifty kilometers, such as was frequently made in Courland, 62,000 steps of an average of eighty centimeters were required. This for a day's march of from nine to ten hours gives an average of five to six kilometers per hour, some 6,000 to 7,000 steps. That makes in the neighborhood of 100 steps per minute, which the correspondent regarded as a considerable accomplishment when allowance is made for the fact that this was kept up hour after hour in full marching equipment.
The column coming from Memel, directed along the Baltic shores, had been steadily moving on Libau. In preparation for the land attack German naval vessels on the 29th of April had bombarded the forts defending the town. On the 6th of May the Russians themselves blew up one of the forts on the eastern front. The shore batteries were soon after silenced by German fire. The German troops advancing from the land side took the forts on the south almost without opposition. Russian troops which had been unloaded at Mitau and sent forward toward the southwest were unable to come up in time to offer any obstacles to the German advance, and on the 8th of May, at six o'clock in the morning, the German soldiers marched into Libau, where they took about 1,500 prisoners, twelve guns, and a number of machine guns.
The Germans immediately turned the metal-working plants of the city to their uses in the manufacture of chains, barbed wire, etc. They also found here a large supply of tools for intrenching work. Most of the Russians of the city had fled. One motive for the German advance into Courland advanced by their enemies was that it was an attempt to include a rich section of country in foraging operations, and it is a fact that the German authorities gave expression to their satisfaction at seizing a region that was of considerable economic value. It is apparent, however, in regarding these operations in the retrospect that they had no small bearing on the German plan of campaign as a whole. It was at the time that the inroad into Courland was started that the signal was about to be given for the great onslaught far to the south on the Dunajec, as described in the account of the Austro-Russian campaign. As the vast campaign along the whole eastern front developed, it became more and more apparent that the position of the German troops in Courland placed them advantageously for taking the Russian line of defenses, of which the fortress of Kovno represented the northern end in the flank in this carrying out of an important part of the vast encircling movement which took all Poland in its grasp. They were a constant threat to the all-important Vilna-Petrograd Railway.
In hostile and neutral countries the Courland invasion provoked comment indicating astonishment at the resources of the Teutonic powers in being able to extend their lines while already fully engaged on an enormous front.
