The march was organised by the Women's Social and Political Union (WSPU).

[3] Charlotte Despard and Flora Drummond on horseback led the march, which included Marjery Bryce dressed as Joan of Arc and 700 women and girls clothed in white to represent suffragette prisoners.

Kate Harvey, Edith Downing and Marion Wallace-Dunlop were among the organisers, and Lolita Roy is believed to have been as well.

[6] Elsie Hooper and other members of the National Association of Women Pharmacists joined the march.

In June 1911 the Chemist and Druggist carried photographs of women pharmacists in the march and reported "Miss Elsie Hooper, B.Sc., was in the Science Section, and several other women pharmacists did the two-and-a-half hours’ march.”[7]
