Masuria Masuria comprised the southeastern portion of the German province of East Prussia, the part of the Reich that was most exposed to a threat from Russia. Two great battles took place here and immediately across the border in Russian Poland in 1914/15. The Russian Army occupied Masuria at the beginning of the war, and remained there until it was defeated at Tannenberg at the end of August 1914. After this battle the remnants of the Russian Second Army, which had entered Masuria from the south, withdrew across the border into Poland.…

Komarów A town in Russian Poland. The war on the Austrian-Russian Front began with a Russian offensive. Four Russian armies were to advance concentrically on Galicia. Facing them were initially three, then four, Austro-Hungarian armies. The Austrians would, at every opportunity, go on the tactical offense as the basis of their defensive strategy. The Austro-Hungarian First and Fourth Armies (Dankl and Auffenberg) met the Russian Fourth (Evert) and Fifth (Plehve) in late summer 1914 east of Kraków (Cracow). The opposing armies were of roughly equal…

Brusilov Offensive The designation “Brusilov Offensive” refers to the Russian army’s last major military operation in the summer of 1916. It was named after the commander of the Russian Southwest Front (Army Group Brusilov), General A.A. Brusilov, whose offensive in the first days of June 1916 annihilated two Austro-Hungarian armies and badly crippled two others. It was one of the greatest Russian victories of the war, but nevertheless exhausted itself in frontal attacks. Born into an aristocratic family, Brusilov earned a reputation as a competent senior commander a…

Eastern Front The topography of the Eastern Front differed markedly from that of the Western Front. For one thing, it was twice as long as the Western Front, stretching in an irregular line from the southeast corner of the Baltic Sea to the Black Sea – including the Bulgarian Front and all the way to the Aegean Sea. Although the terrain was mainly gently rolling, or else flat and forested, the Carpathian Mountains along the Polish and Hungarian borders could pose a significant obstacle for militar…

Przemyśl The main Austro-Hungarian fortress in Galicia, was situated above the River San, which represented a relatively advantageous line of defense in central Galicia. The Fortress of Przemyśl also controlled the communication lines running through the Carpathian Foothills to Hungary, but had only been insufficiently modernized prior to the war. It first attracted attention in mid-September 1914 when the Austro-Hungarian Army took refuge in Przemyśl after having been defeated in the east and no…

Narew Offensive In mid-June of 1915, the Russian High Command (Stavka) reviewed the depressing military situation at a conference in Cholm (Chełm). The conference was called in the aftermath of the defeat in Galicia and the Russian Army was now half a million men understrength. In the north, in Courland, the German Army Group Lauenstein (later: Army of the Neman) was now in a favorable position that enabled it to level threats both at Riga, Russia’s most important Baltic port and one of Russia’s m…

Bug Offensive On June 22, 1915, the Austro-Hungarian Second Army recaptured Lemberg (Lviv), the capital of Galicia, which had been held by the Russians since September of the previous year. For the Central Powers, this event marked the high point of an important series of successes that had begun in May with the breakthrough at Gorlice-Tarnów. The reduction of the salient in Russian Poland seemed within reach, and there appeared to be a realistic chance of encircling the strong Russian forces in t…

Gorlice-Tarnów, Battle of Two towns in Galicia (now situated in modern Poland). Even though the German Supreme Army Command was determined to decide the war in the West, developments in early 1915 brought the focus of attention to the East. The weaker the Austro-Hungarian army became, the more the German allies felt compelled to provide direct support. The situation deteriorated when Italy, hoping for territorial gains, threatened the Dual Monarchy with war. Now the German Eleventh Army (August von…
