After the battle of Lubaczow the Russian line drew back about twenty miles. For the defense of Lemberg the front ran in a concave form from along the River Tanev, five miles from Rawa-Ruska, down to Grodek and Kolodruby; then eastward behind the Dniester to Zuravno and Halicz. The marshes of the Dniester, then swollen by heavy rains, formed a good natural defense; the intrenchments on the hills north of Grodek to Rawa-Ruska protected the approaches to Lemberg from that direction. The weakest spot lay around Janov, fifteen miles north of Grodek, where the level ground would permit the easy transport of heavy artillery. This position had been fortified with trenches and wire entanglements. Here also were concentrated the troops withdrawn from other parts of the line, and four armored trains with quick-firing guns from the depot at Rovno. General Ivanoff had no intention of making any decisive stand against the "phalanx"; neither did he think of risking his armies in a battle for Lemberg. That town was certainly of great military and political importance--worth a dozen Przemysls--and worth fighting for. But for that he would need artillery in enormous quantity. Von Mackensen carried 2,500 guns with him, as well as siege trains of heavy howitzers. Ivanoff possessed none of these, and could therefore hope only to fight rear-guard actions while retiring before Von Mackensen. In any other part of the Galician line except the center he had little to fear. We left Von Linsingen forcing the Dniester at Zuravno. He got the bulk of his army across, the main advance commanded by Von Bothmer, who captured the northern heights and penetrated the forests near the Stryj-Tarnopol railway. They were less than fifty miles from Lemberg. The "retreating" Brussilov suddenly turned round and fell on Von Bothmer's advance. The fight lasted three days, with the result that the Austro-Germans were obliged to fall back across the Dniester, leaving behind 2,000 killed and wounded, besides 17 guns, 78 machine guns, 348 officers and 15,430 men as prisoners, June 8-10, 1915. On June 11, 1915, however, the Germans renewed the attack on Zuravno, recaptured the town, and on June 12 were five miles north of it. By June 13 they had made ten miles, when Brussilov lashed out again. Within two days the Germans were back on the Dniester. Von Mackensen had meanwhile concentrated a new series of heavy batteries around Jaroslav and formed a new "phalanx" (with reenforcements) west of the San between Piskorovice and Radymno. Another attempt was preparing to break through Ivanoff's right wing.
