In a protest of the conditions in Occoquan, Alice Paul commenced a hunger strike[4], which led to her being moved to the prison’s psychiatric ward and force-fed raw eggs through a feeding tube. This, combined with the continuing demonstrations and attendant press coverage, kept pressure on the Wilson administration.[3] In January, 1918, Wilson announced that women’s suffrage was urgently needed as a “war measure”, and strongly urged Congress to pass the legislation. In 1920, after coming down to one vote in the state of Tennessee, the Nineteenth Amendment to the United States Constitution secured the vote for women.
