While the struggle for the passes was raging in the central Carpathians an interesting campaign was being conducted in Eastern Galicia and the Bukowina between Von Pflanzer-Baltin and Lechitsky. There we left the Russians in possession of Stanislawow, which they had reoccupied on March 4, 1915. Two days before, an Austrian detachment of infantry and two divisions of cavalry attempted a raid into Russian territory near the Bessarabian frontier. Within forty-eight hours they were hurled back. Beyond local skirmishes and maneuvering for positions, nothing of importance happened from March 4 till the 15th, when the Russians attacked the main Austrian forces southeast of Czernowitz. Crossing the River Pruth opposite Ludihorecza, which lies about 600 feet high, and where the Czernowitz waterworks are situated, the Russians occupied the place and threatened the Austrian position in the town, around which pressed laborers were digging trenches night and day for the defenders. Along the line between Sadagora and Old Zuczka the Russians had been settled for over six months. The Austrians attacked this position on March 21, 1915, with the aid of reenforcements and compelled the Russians to evacuate Sadagora. While falling back in the south the Russians endeavored to advance in the north, from the direction of Czerniavka, and outflank the Austrians. Violent fighting raged for several days, especially northeast from Czernowitz to beyond Rarancze, with the result that the Russians were compelled to withdraw toward Bojan, near their own frontier, on March 27. Three days later some Hungarian Honved battalions, who had penetrated into Russian territory near Szylowce, were surrounded by Cossacks and severely handled. Besides many killed and wounded the Austrians lost over 1,000 prisoners, and by April 2, 1915, the Russians had thrown the remainder back across their borders. On April 10, 1915, the Russians withdrew from Boyan, but returned on the 14th. Here, at the close of April, they concentrated large reenforcements and recovered most of the ground they had lost since the middle of March.
Some twenty miles northwest of Czernowitz, sheltered in a loop of the Dniester, lies an important fortified town called Zaleszczyki. It had a population of over 76,000, and is a station on the branch line connecting Czortkow junction with the Kolomca-Czernowitz railway. From the dense forests east of the town an Austrian column commanded by Count von Bissingen had attempted during the night of March 22-23, 1915, to turn the adjacent Russian positions, held by Cossacks and Siberian fusiliers. A furious fight developed, and the Austro-Hungarian column, which included some of the finest troops, was repulsed with heavy loss. Two other attempts were made here, on April 10 and 17, 1915. On the latter date a detachment of Tyrolese sharpshooters were trapped in the wire entanglements and annihilated.
One more battle on a big scale remains to be chronicled from the far eastern sector; it may also serve to illustrate the wide divergence that not infrequently exists between official communiqués recording the same event. Early in April, 1915, a Russian force threw a bridge across the Dniester near the village of Filipkowu and moved along the road running from Uscie Biskupie via Okna and Kuczurmik on to Czernowitz, the intention being to turn the Austrian positions south of Zaleszczyki from the rear. We will let the rival communiqués relate what happened:
| Austrian Version | Russian Version | |
| Annihilated two battalions of Russian infantry belonging to the Alexander Regiment; took 1,400 prisoners, and drove Russians back beyond the Dniester. | Annihilated two battalions of the Honveds; captured 21 officers, over 1,000 rank and file, and 8 machine guns. |
The curtain was about to rise for the next act, wherein will be played one of the most terrific reversals of fortune ever produced in military history.
For quite a month it had been an open secret that considerable masses of German troops were being transported to the Carpathian front. What was not known, however, was the magnitude or the plan of these preparations. Never was a greater concentration of men and machinery more silently and more speedily accomplished. All along the south of the range, on the great Hungarian plains, there assembled a gigantic host of numerous nationalities. But it was away to the west, in that narrow bottle neck where the Dunajec flows from the Polish frontier down to the Tarnow Pass, that the mighty thunderbolt had been forged. Thousands of heavy guns were here planted in position, and millions of shells conveyed thither under cover of night. Countless trains carried war materials, tents, pontoons, cattle, provisions, etc. Finally the troops arrived—from the different fronts where they could be spared, and new levies from Germany and Austria-Hungary. Smoothly and silently men and machines dropped into their respective places: All was ready; not a detail had been overlooked; German organization had done its part. The commander was Von Mackensen, nominally Commander of the Eleventh German Army, but in reality supreme director of the whole campaign.
During April, 1915, a number of changes had taken place among the commanding officers of the Austro-German armies; the new dispositions of groups along the battle line differ considerably from those which obtained during the fighting for the passes. The line was now enormously strengthened, and more compact. This applies only to the Germanic side; there is little change on the Russian. At this stage the Russian front on the west of Galicia extended from Opatovie on the Polish frontier along the Dunajec, Biala, and Ropa Rivers by Tarnow, Ciezkovice, and Gorlice down to Zboro in Hungary; from here it runs eastward past Sztropko, Krasnilbrod, Virava, and Nagy Polena to the Uzsok Pass, a distance of about 120 miles. Ewarts commanded the army on the Nida; the Dunajec-Biala line was still held by Dmitrieff, Commander in Chief of the Eighth Russian Army; Brussilov still commanded the main army of the Carpathians, and Lechitsky in the Bukowina in the place of Alexeieff, who had succeeded General Russky in the northern group. The whole southern group, from the Nida to the Sereth inclusive, was under the supreme command of General Ivanoff. Facing Dmitrieff on the Dunajec front stood now the Fourth Austro-Hungarian Army under the Archduke Joseph Ferdinand, about five army corps, including a German cavalry division under General von Besser; then the Ninth and Fourteenth Austrian Army Corps; to their right, several Tyrolese regiments; the Sixth Austro-Hungarian Army Corps of General Arz von Straussenburg, with the Prussian Guards on his left and Bavarian troops under Von Emmich on his right; the Eleventh German Army Corps under Von Mackensen; the Third Austro-Hungarian Army under General Boroyevitch von Bojna; the Tenth Army Corps under General Martiny. This formidable combination now confronted the Dunajec-Biala positions, which Dmitrieff had held without exertion for four months. Only a mile or two away he still inspected his trenches and conducted his minor operations, totally unconscious of the brewing storm specially directed against him. The Laborza district was held by the Archduke Joseph with the Seventh Army Corps; on his left stood a German corps under Von Marwitz, and on his right the Tenth Army Corps, north of Bartfeld, with some additional forces in between. Around the Lupkow and Uzsok passes the Second Austro-Hungarian Army under Boehm-Ermolli was stationed where it had been since February, 1915. Next, on the right, the Austro-Hungarian army corps under Von Goglia; in the Uzsok lay an army under Von Szurmay, nearly all Magyars, of whom the chief commander was Von Linsingen. Farther eastward stood a Prussian corps, embodying a division of Prussian Guards and other regiments commanded by General Bothmer, a Bavarian, who had been reenforced with a Hungarian division under Bartheldy; then followed the corps of Generals Hofmann and Fleischman, composed of all Austrian nationalities, intrenched in the mountain valleys. More German troops held the next sector, and, finally, came Von Pflanzer-Baltin's army groups in the Bukowina and Eastern Galicia. Against this huge iron ring of at least twenty-four Germanic corps (about 2,000,000 men) and a great store of reserves, the Russians could not muster more than about fourteen of their own corps. As has already been pointed out, the greatest disparity of strength existed on the Dunajec line, where Dmitrieff stood opposed to about half of the enemy's entire force with only five corps of Russian troops. The Austro-German forces, moreover, were infinitely better equipped with munitions and heavy artillery. The lack of big guns was undoubtedly the reason why the Russians had not attempted an invasion of Hungary. Hence they stuck to the mountain passes where their opponents were unable to carry their artillery, although they were amply supplied with the same. It is true that the Russians could have produced an equal—or even greater—number of men, but they had not the arms and accouterments.
Speaking from safe knowledge after the event, it is possible to indicate with moderate accuracy at least one of the ingenious stratagems adopted by the Germans to disguise their tremendous preparations against the Dunajec line. For months the fighting in this region had never been severe. When, therefore, local attacks and counterattacks on a small scale started on the Biala, as far back as April 4, 1915, Dmitrieff and his staff regarded this activity on the Austrians part as merely a continuation of the sporadic assaults they had grown accustomed to. Besides holding his own, Dmitrieff had on several occasions been able to assist Brussilov on his left. Until the big German drive commenced they had only been opposed to three Austro-German army corps and a Prussian division; now there were twelve corps on their front, supplied with enormous resources of artillery, shells, and cavalry. Most serious of all, Dmitrieff had neglected to construct second and third lines to which he could retire in an emergency. Of the rivers that lay behind him—the Wisloka, the Wistok, and the San—the first would be useful to cover Brussilov's position at the western passes, but beyond that he could not retreat without imperiling the whole Carpathian right flank. It was on this very calculation that the German plan—simple but effective—was based. The Russian grip on the Carpathians could only be released either by forcing a clear road through any pass into Galicia, or by turning one of the extreme flanks. Had the Austrians succeeded in breaking through as far as Jaslo, Dmitrieff would have been cut off and Brussilov forced to withdraw—followed by the whole line. The same result would follow if a thrust from the Bukowina succeeded in recapturing Lemberg. Both methods had been attempted, and both had failed. Germany's overwhelming superiority in artillery could not be effectively displayed in mountain warfare, but Dmitrieff's position on the Dunajec offered an easy avenue of approach.
At the eleventh hour Dmitrieff grasped the situation and applied to Ivanoff for reenforcements. Owing to some blunder the appeal never reached the Russian chief, and Dmitrieff had to do the best he could. Nothing now could save his small force from those grim lines of gaping muzzles turned against his positions. The overture began on April 28, 1915, with an advance on the Upper Biala toward Gorlice, by Von Mackensen's right. Here some minor attacks had been previously made, and the gradually increasing pressure did not at first reveal the intent or magnitude of the movement behind it. Meanwhile the German troops about Ciezkovice and Senkova—respectively northwest and southeast of Gorlice—were moving by night nearer to the battle line. The Russian front line extended from Ciezkovice in a southeasterly direction. Hence it soon became clear that Gorlice itself was to be the main objective of the attack. A Russian official announcement of May 2, 1915, boldly states:
"During the nights of April 30 to May 1 strong Austrian forces opened an offensive in the region of Ciezkovice. Our fire forced the enemy to intrench 600 paces in front of our trenches." Furthermore, the Germans at the same time had directed artillery fire and bayonet attacks against various points on the Rava, Pilica, Nida, and the Dunajec. These, however, were merely movements aiming at diversion, meant to mask the intentions of the main attack and to mislead the Russians. On the evening of May 1, 1915, the German batteries began experimenting against the Russian positions. This was kept up all night while the engineers attempted to destroy the first line of the Russian wire entanglements. During the same night the Austrians dragged several heavy howitzers across the road from Gladyszow to Malastow, and got them into position without the knowledge of the Russians. In the morning of May 2, 1915, the great batteries began to roar against the Russian line—a fire such as had perhaps never been witnessed before. A spectator thus describes the scene: "In one part the whole area was covered with shells till trenches and men were leveled out of existence." It was reported that 700,000 shells had been fired in the space of four hours, for which period this preliminary bombardment lasted. The Russian line was turned into a spluttering chaos of earth, stones, trees, and human bodies. The German and Austrian batteries then proceeded to extend the range, and poured a hurricane or shells behind the enemy's front line. This has the effect of doubly isolating that line, by which the survivors of the first bombardment cannot retreat, neither can reenforcements be sent to them, for no living being could pass through the fire curtain. Now is the time for the attacker's infantry to charge. Along the greater part of the Ciezkovice-Walastow line this stage was reached by ten o'clock in the morning or May 2, 1915.
