Both sides in World War I were stuck in a stalemate, with neither wanting a grueling war. New combatants, including Australia, Italy, and Japan, joined the war, and the Ottoman Empire entered on the side of the Central Powers. Germany began to use chemical weapons and submarines to attack the Allies, while the Allies also engaged in chemical warfare. In 1916, the longest and bloodiest battle of the war began, with the Germans attacking the French around the city of Verdun, and the French asking their allies to draw the Germans away. The British launched the Battle of the Somme with 60,000 casualties on the first day. Further battles occurred, and by 1917, everyone was exhausted. Russia had an uprising, followed by a revolution, and withdrew from the war. Despite winning some battles, the Central Powers began to collapse, and Germany was forced to surrender in 1918, accepting war guilt and paying the bill for the war.
