red cross no more hanging my flag out the window then,
In July 1870, following the outbreak of war between France and Prussia, Colonel Loyd-Lindsay (later Lord Wantage of Lockinge) wrote a letter to The Times calling for a National Society to be formed in Britain following the example of other European nations. On 4 August 1870 a public meeting was held in London and a resolution passed that "a National Society be formed in this country for aiding sick and wounded soldiers in time of war and that the said Society be formed upon the Rules laid down by the Geneva Convention of 1864".
The British National Society for Aid to the Sick and Wounded in War was formed, giving aid and relief to both warring armies during the Franco-Prussian War and in subsequent wars and campaigns during the 19th century under the protection of the red cross emblem.
In 1905 the British National Society for Aid to the Sick and Wounded in War was reconstituted as British Red Cross and granted its first Royal Charter in 1908 by HM King Edward VII and Queen Alexandra, who became its president.
The Red Cross required a huge number of skilled volunteers if it was to be prepared for its wartime role. In 1907 a permanent structure of local Branches was adopted and extended the presence of the British Red Cross to communities around the country.
The Voluntary Aid Scheme was introduced in 1909 and ensured that Voluntary Aid Detachments (VADs) were formed in every county in England whose members would provide aid to the territorial medical forces in times of war.
