As well as his army positions, Kelly-Kenny was very interested in politics in his native County Clare. In the Second Anglo-Boer War he was , as a Lieutenant-General, General Officer Commanding the 6th Division of the South African field forces. He was twice mentioned in dispatches and received the Queen's South African Medal with four clasps. He was involved in the relief of Kimberley, the battles of Paardeberg, Poplar Grove and Driefontein. Lieutenant-General Kitchener was appointed commander and over-ruled Kelly-Kenny's plan to besiege Cronji and bombard his force from a safe distance. Kitchener ordered an assault on the Boer trenches. The result was "Bloody Sunday" - an unnecessary sacrifice of hundreds of lives on the British side. Kelly-Kenny was involved in the engagements at Poplar Grove and Driefontein where the 6th Division distinguished itself. These were viewed as key to destroying the Boer morale and winning the war. General Kelly-Kenny was a close friend of King Edward VII. Appointments made, at the insistence of the King, were often challenged. Due to his loyalty and abilities Kelly-Kenny was appointed Knight Commander of the Order of the Bath and received a knighthood in a private audience. Once again others tried to have him moved from the War Office but the King intervened again and he remained in his position. He was conferred with the Knight Grand Cross of the Order of the Bath (1904), Grand Cross of the Red Eagle (1905 - Germany), Grand Cross of the Rising Sun (1906 - Japan) and on his return to Britain he received the Knight Grand Cross of the Royal Victorian Order (1906) Individual image taken from photographed poster of tobacco and cigarette cards.kell-kenny, county clare, lieutenant-general, kimberley, queen's south african medal, paardeberg, poplar grove, driefontein, kitchener, bloody sunday, cronji, boer war, trenches, knight commander of the order of the bath, war office, king, king edward vii, knight grand cross of the order of the bath, grand cross of the red eagle, grand cross of the rising sun, knight grand cross of the royal victorian order

His military career led him to become appointed as assistant military secretary to the General Officer Commanding Cape Colony in 1895. He went to Southern Rhodesia in 1896 to disarm the local police force following the Jameson Raid and then later to command the Matabele Relief Force during the Second Matabele War. In 1899 he returned to Southern Rhodesia as Lieutenant-Colonel where he led the Siege of Mafeking during the Second Boer War.
