However, the NUWSS membership included those who were against war. When Fawcett turned the NUWSS to war work, eleven pacifist members resigned, later to join the Women's International League for Peace and Freedom (WILPF). Like the NUWSS, the more militant Women's Social and Political Union (WSPU) led by Emmeline and Christabel Pankhurst chose to cease their obstructive activism for women's votes and instead advocated the alignment of British women to the cause of war. However, in October 1914, Sylvia Pankhurst travelled to Glasgow and spoke out against the war, becoming one of the first suffragettes to do so. She said that "peace must be made by the people and not by the diplomats". Though pacifist, Sylvia Pankhurst held with her mother and sister to the general agreement that suffragettes would abstain from militant activism for the duration—she arranged for activist women to join with the War Emergency Worker's Committee and fill some of the positions that had been abandoned by men leaving for war. In "Jus Suffragii" in December 1914, Carrie Chapman Catt published a letter that she had received earlier from Anita Augspurg, Lida Gustava Heymann, and several other German women activists including presidents of woman suffrage societies in Germany. The letter was entitled "To the International Woman Suffrage Alliance, through its president, Mrs. Chapman Catt." It began, "To the women of all nations warm and hearty greetings in these wretched and bloody times." The German women expressed that the "criminally rekindled war" should not separate women from all countries who had previously been united "by the common striving for the highest object—personal and political freedom". They stated that "True humanity knows no national hatred, no national contempt. Women are nearer to true humanity than men." Catt published another letter from German women's rights activist Clara Zetkin, one that expressed the desire for all women not to let "the thunder of guns and the shouts of the jingoes" make them forget that the rise of civilisation amongst the European countries held much in common. Zetkin wrote that the women of the world should guard their children against the "hollow din" of "cheap racial pride" which filled the streets, and that "the blood of dead and wounded must not become a stream to divide what present need and future hope unite". In response to the letters from Germany, Emily Hobhouse organised the writing and signing of a peace-promoting letter from British women: the Open Christmas Letter.
