Why did Germany agree to the armistice on November 11, 1918?

"The armistice that ended the First World War (1914-18) on the Western Front was signed between Germany and the Allies on 11 November 1918. The guns fell silent at 11:00 a.m. that day. The Allies, who included Britain, France, and the United States, had defeated Imperial Germany and its allies, who included Austria-Hungary and the Ottoman Empire. Around 11 million people were killed in the world's first global conflict."

"Thanks to improved tactics, a better coordination of combined arms (infantry, artillery, and air support), superior equipment, the better use of new technology like tanks, and a large influx of new troops from the United States, the German Army was pushed back, losing most of the territory it had gained in the spring. While the Allies were increasing the number of men at the front, Germany was running out of soldiers in this long war of attrition."

"Within the space of 100 days the Allies took 363,000 German soldiers prisoner (25 per cent of the army in the field) and captured 6,400 guns (50 per cent of all German guns on the Western Front). These numbers show the effectiveness of the Allied strategy and the low morale of the German soldiers. (Winter, 170) Germany and its main ally, Austria-Hungary, made their first moves for a surrender by sending word to United States President Woodrow Wilson (1856-1924) at the end of September."

The armistice that ended fighting on the Western Front was signed on 11 November 1918, and the guns fell silent at 11:00 a.m. The Allies, including Britain, France, and the United States, defeated Imperial Germany and its allied empires. Around 11 million people were killed in the global conflict. The Treaty of Versailles imposed harsh terms on Germany: war guilt, territorial losses, reparations, and strict limits on its armed forces. During summer 1918 Allied advances in the Hundred Days Offensive, aided by improved tactics, combined arms, tanks, and U.S. reinforcements, pushed back and demoralized the German Army, producing large prisoner and artillery captures.
