Baird's most significant achievement was the defeat of the Indian ruler of Mysore, Tipu Sahib, at Seringapatam in 1799. By this action, British ascendancy in southern India was assured and the influence of France diminished in the sub-continent. Ten years later Baird was with General Sir John Moore in Spain; he was injured at Corunna and lost an arm. Sir David's wife considered that her husband had been insufficiently rewarded. After his death, she commissioned Wilkie to paint a heroic picture in which the general is seen discovering the dead body of Tipu Sahib. The painting now hangs in the National Gallery of Scotland. This is Wilkie's study for the head which he based on an engraving after a portrait by Raeburn.
