"On the 2nd of May [1915] at 6 a.m. an overwhelming artillery fire, including field guns and running up to the heaviest calibers, was begun on the [Russian] front many miles in extent selected for the effort to break through. This was maintained unbroken for four hours.At 10 o'clock in the morning these hundreds of fire-spouting tubes suddenly ceased and the same moment the swarming lines and attacking columns of the assailants threw themselves upon the hostile positions. The enemy had been so shaken by the heavy artillery fire that his resistance at many points was very slight. . . .On the evening of the 2nd of May, when the warm Spring sun had begun to yield to the coolness of night the first main position in its whole depth and extent, a distance of some sixteen kilometers, had been broken through and a gain of ground of some four kilometers had been attained."
Excerpts from a description of the first day of the Gorlice-Tarnow Offensive by the victorious German commander August von Mackensen leading the German-Austro-Hungarian forces. The attackers fired as many as 700,000 shells in the devastating opening bombardment. Suffering from a lack of munitions, the Russians could respond with little but the men themselves. Continuing through September 30, Mackensen's campaign would spread across the entire Eastern Front and drive Russian forces back as much as 300 miles.
