German offensive

During World War I, the Eastern Front (sometimes called the “Second Fatherland War” in Russian sources) was a theatre of operations that encompassed at its greatest extent the entire frontier between the Russian Empire and Romania on one side and the Austro-Hungarian Empire, Bulgaria and Germany on the other. It stretched from the Baltic Sea in the north to the Black Sea in the south, included most of Eastern Europe and stretched deep into Central Europe as well. The term contrasts with “Western Front”. Despite the geographical separation, events in all the European theaters strongly influenced one another. In 1914, the Russians’ invasion of Galicia relieved the pressure on the Serbian Front, and in 1916, the Brusilov Offensive was intended to do the same for the Italian Front. Ultimately, both times the Russians ignored the German forces to their north, which resulted in them over-stretching their supply lines, then suffering further defeats against superior German artillery.
