With the outbreak of the First World War, all WSPU activity came to a halt and the NUWSS turned much of their focus to relief work.[54][55] The WPSU, reformed as the Women's Party from 1917, sent members across Wales, no longer to rally for suffrage but to encourage male volunteers to join the British Army.[56] In 1915 Flora Drummond attended a rally in Merthyr to demand that men leave occupations that women could undertake, and to stop 'hiding behind the petticoats'.[57] Women in Wales took up employment en masse, especially in newly opened munitions factories, and in 1918 the Newport Shell Factory had a female workforce of 83 per cent while the Queensferry factory was 70 per cent.[58]
