the leader of the National American Woman Suffrage Association - believed that the best way to realize women's suffrage was to gain the vote through individual states first, upon which women could vote for a pro-suffrage majority in Congress. Until late 1915, she thus opposed advocating for a national amendment to grant women's suffrage, as the NWP did. Members of the National American Woman Suffrage Association feared that pickets would create a backlash from male voters. Anti-suffragists also opposed the Silent Sentinels' protest. Mobs sometimes attempted to deter the Silent Sentinels through violence (which increased after US entry into World War I). For example, some attacked the Silent Sentinels and tore their banners to shreds. This occurred especially with the more provocative banners, such as banners calling Woodrow Wilson "Kaiser Wilson." At first President Wilson was not very responsive to the women's protest. At points he even seemed amused by it, tipping his hat and smiling. It was said that at one point Wilson even invited them in for coffee; the women declined. At other points in time, he ignored the protests altogether, such as when the Sentinels protested on the day of his second inauguration ceremony. As the Sentinels continued to protest, the issue became bigger and Wilson's opinion began to change. Although he continued to dislike the Silent Sentinels, he began to recognize them as a group seriously presenting him with an issue. Occoquan Workhouse and the Night of Terror On June 22, 1917, police arrested protesters Lucy Burns and Katherine Morey on charges of obstructing traffic because they carried a banner quoting from Wilson's speech to Congress: "We shall fight for the things which we have always carried nearest our hearts—for democracy, for the right of those who submit to authority to have a voice in their own governments." On June 25, 12 women were arrested, including Mabel Vernon and Annie Arniel from Delaware, again on charges of obstructing traffic. They were sentenced to three days in jail or to pay a $10 fine. They chose jail because they wanted to show commitment to their cause and their willingness to sacrifice their physical bodies. On July 14, 16 women, including Matilda Hall Gardner, Florence Bayard Hilles, Alison Turnbull Hopkins, and Elizabeth Selden Rogers (of the politically powerful Baldwin, Hoar & Sherman family) were arrested and sentenced to 60 days in jail or to pay a $25 fine.
