Sir Vincent Hunter Barrington Kennett-Barrington (1844-1903), was a humanitarian worker and businessman. He was associated with the British League of the Order of St John of Jerusalem, which in turn led to his involvement with the Society for Aiding and Ameliorating the Condition of the Sick and Wounded in the Time of War (known as the National Aid Society and later, as the Red Cross).

He was involved in providing humanitarian assistance to both sides in the Franco-Prussian War of 1870-71. Following the armistice he became further involved in humanitarian work in eastern France, and went on to provide help during the Carlist War in Spain (1873-5), the Serbo-Turkish War (1876-7), and the Turko-Russian War (1877-8).

This is a collection of some of his letters home and to the National Aid Society from the war front in Spain in the 1870s.
