Fitzroy James Henry Somerset, 1st Baron Raglan

Raglan lost his right arm at Waterloo, married Wellington's niece, and was in charge of the British troops in the Crimea during the war of the same name. His orders to the Light Brigade, commanded by the Earl of Cardigan, lead to the infamous charge and later a poem by Tennyson. "Into the valley of death ..." and all that. It also caused Pierre Bosquet, an observing French general, to remark: "C'est magnifique, mais c'est ne pas la guerre." I'm not sure if Bosquet was wearing a pullover or not.
