Wellesley went to India in 1797, studying books on war and military tactics during the long voyage. The effort paid off. In 1802 he confronted a force of 50,000 French-led Maratha soldiers at Assaye. Through an unconventional choice of field positions and brave leadership in a bloody battle, Wellesley won against imposing odds. He later called it the finest thing he had ever done in the fighting line.
Returning home in 1805, Wellesley was knighted, married the short-sighted, timid Kitty Pakenham (with whom he was never happy) and was sent for brief stints of duty in Denmark and Ireland, where he distinguished himself further. But it was his departure to fight the French on the Iberian Peninsula in 1808 that almost ended his career: frustrated by shared commands with inept generals, he rashly signed a treaty with the French without reading its foolish terms. He was hauled before an inquiry and criticized—but survived to advise the secretary of war, Viscount Castlereagh, on how he would wage cheap but effective war. Castlereagh gave him the job that marked the start of Wellesley’s ascent to greatness.
Here, the British army had enough men to conduct defensive campaigns, and even to besiege large towns and castles, but insufficient strength to take advantage of these successes. He defeated the French at Talavera (for which he received a peerage, becoming Viscount Wellington), and managed to defend Lisbon from French attack by secretly building a network of fortifications. Despite a succession of British victories, at Vimeiro, Busaco, Almeida and elsewhere, Viscount Wellington was often frustrated in his ambitions to press on from Portugal into Spain.
By 1812 things had improved. Wellington fought his way to Madrid and persuaded the Spanish government to appoint him
By now Wellington was the most famous man in England. He had won a dukedom, the ambassadorship to France, and the role as British representative at the Congress of Vienna. He was the recipient of honors from governments of Europe. But in 1815 he was to face the ultimate test of his military mettle.
Napoleon, who had abdicated and then been exiled to Elba in 1814, had escaped and begun to rally troops around him. Wellington was the only man in Europe considered worthy enough to command the allied forces against the emperor as he plotted to attack the Low Countries. Wellington was unimpressed by his own combined forces, calling them “an infamous army, very weak and ill equipped.” He also had little knowledge of Napoleon’s plans for the battlefield and was taken aback when French troops began to move on June 15, 1815. “Napoleon has humbugged me, by God!” he exclaimed; but when the two armies met on June 18, Wellington had arranged his forces into a defensive formation that was to prove extremely resilient against the waves of bludgeoning French attacks that Napoleon launched.
Throughout the long, hard battle, Wellington remained calm, though his Prussian reinforcements, under Marshal Blücher, arrived late and virtually every man of his personal staff was killed or wounded. “I never took so much trouble about any battle, and was never so near being beat,” he wrote afterward. But this victory, his last, was resounding, and Wellington was lauded right across the continent.
As a commander, Wellington was distinguished by his acute intelligence, sangfroid, planning and flexibility but also by his loathing for the suffering of battle. As a man, he was sociable, enjoying close friendships with female friends and a long line of affairs with high-born ladies and low-born courtesans, including a notorious French actress whom he shared with Napoleon himself. When one such courtesan threatened him with exposure, he replied: “Publish and be damned.”
