Karl Liebknecht had opposed the war from the beginning and was the only member of the Reichstag to vote against continued funding. The government tried silencing him by forcibly conscription. He returned to Germany due to ill-health after serving as a gravedigger on the Russian front. After he led an anti-war rally in Berlin, 1916, he was arrested and on June 28 convicted for treason and sentenced to two years hard labor. In response, 55,000 workers went out on strike for 3 days to protest.
