spring and summer of that year, a German-Austrian offensive drove the Russians out of Galicia and Poland and destroyed several Russian army corps. In 1916 the Germans planned to drive France out of the war with a large-scale attack in the Verdun area, but a new Russian offensive against Austria-Hungary once again drew German troops from the west. These actions left both major fronts stable and both Russia and Germany despairing of victory—Russia because of exhaustion, Germany because of its opponents' superior resources. Toward the end of 1916, Russia came to the rescue of Romania, which had just entered the war, and extended the eastern front south to the Black Sea. Wartime agreements among the Allies reflected the Triple Entente's imperialist aims and the Russian Empire's relative weakness outside Eastern Europe. Russia nonetheless expected impressive gains from a victory: territorial acquisitions in eastern Galicia from Austria, in East Prussia from Germany, and northeastern Anatolia from the Ottoman Empire, which joined the war on the German side; control of Constantinople and the Bosporus and Dardanelles straits; and territorial and political alteration of Austria-Hungary in the interests of Romania and the Slavic peoples of the region. Britain was to acquire the middle zone of Persia and share much of the Arab Middle East with France; Italy—not Russia's ally Serbia—was to acquire Dalmatia along the Adriatic coast; Japan, another ally of the Entente, was to control more territory in China; and France was to regain Alsace-Lorraine, which it had lost to Germany in the Franco-Prussian War, and to have increased influence in western Germany. Fatal weakening of tsarism The onset of World War I exposed the weakness of Nicholas II's government. A show of national unity had accompanied Russia's entrance into the war, with defense of the Slavic Serbs the main battle cry. In the summer of 1914, the Duma and the zemstva expressed full support for the government's war effort. The initial conscription was well organized and peaceful, and the early phase of Russia's military buildup showed that the empire had learned lessons from the Russo-Japanese War. But military reversals and the government's incompetence soon soured much of the population. German control of the Baltic Sea and German-Ottoman control of the Black Sea severed Russia from most of its foreign supplies and potential markets. In addition, inept Russian preparations for war and ineffective economic policies hurt the country financially, logistically, and militarily.
