World War One: 1917

In 1916, World War I shifted to a war of attrition. Germany resumed unrestricted submarine warfare, risking US involvement. The US joined the Allies after the Zimmermann telegram and Russian revolution. Key battles like Arras and Vimy Ridge occurred, with air warfare intensifying. French mutinies and strategic shifts marked 1917. The U-boat war saw convoy systems reducing losses. Major offensives like Passchendaele and Caporetto took place. New Allies joined, and the Middle East saw significant campaigns. The Eastern Front ended with Russia's exit, and Germany planned a 1918 offensive.
