the right of Dankl the Austro-Hungarian 4th Army, aiming at Cholm, drove back the Russian Fifth Army under Pavel Plehve in the Battle of Komarów, capturing 20,000 prisoners and inflicting heavy casualties. However, a planned Austrian enveloping movement around the Russian army failed. As the Russians were being driven back along the northern front, the Austrian 3rd Army and Army Group Kovess made a simultaneous advance against Ivanov's left wing. Along the southern front, Ivanov had the Russian Third Army under Nikolai Ruzsky and the Russian Eighth Army under Aleksei Brusilov. Brusilov and Ruzsky routed the Austro-Hungarians so thoroughly that even though poor roads necessitated that the Russians halt for two days, the Austrians could not regroup to halt the Russian drive. This attack became known as the Battle of Gnila Lipa. With the entire 3rd Army and Kovess Group in full retreat, Conrad pulled forces away from the northern front which he believed had been sufficiently defeated. In fact, the Russians north of Lemberg were still a potential threat. Ivanov ordered Plehve's Fifth Army to attack and drove the Austrians back as they began to shift forces to the south in an engagement known as the Battle of Rava Ruska. The Austrian Second Army was quickly recalled from Serbia, but it was too late and the entire Austrian front collapsed in Galicia, and the Russians took control of Lemberg. Results Holger Herwig estimates Austro-Hungarian losses of 100,000 dead, 220,000 wounded and 100,000 captured. According to Prit Buttar, the Austro-Hungarian army lost 324,000 men in Galicia, including 130,000 as prisoners, while the Russians lost 225,000 men, of which 40,000 were captured. Other authors estimate 400,000 Austro-Hungarian losses, or "one-third of the Austro-Hungarian Army's combat effectives", and 250,000 for the Russians. The Russians had pushed the front 100 miles (160 kilometers) into the Carpathian Mountains, completely surrounded the Austrian fortress of Przemyśl and started a Siege of Przemyśl which lasted for over a hundred days. The battle severely damaged the Austro-Hungarian Army, killed a large portion of its trained officers, and crippled Austria-Hungary. Though the Russians had been utterly crushed at the Battle of Tannenberg, their victory at Lemberg prevented that defeat from fully taking its toll on Russian public opinion.
