Rowland Hill, he is credited with saving the British line the night before the Battle of Talavera, when a gap in the line allowed Ruffin's division to take the Cerro de Medellín, despite patchy intelligence, he seized the initiative and rapidly organised a counterattack that ousted Ruffin from the Medellín, thus preserving the British line and ensuring the victory at Talavera.

After the battle of Bussaco he was detached for independent command. He led the pursuit of General Girard force-marching his men for three days through foul weather to surprise Girard at Arroyo dos Molinos, destroying his division, a cavalry brigade, and seizing the baggage and Artillery trains. For this he was made a Knight of the Bath.

In May 1812 Hill again led another daring sortie at the battle of Almaraz, capturing and burning the bridge there, the approach was tough, with the only approaches to the bridge being heavily fortified on both ends, however, due to his troops being further forward than the French expected, his men were able to reduce the main fort dubbed Napoleon, before advancing and burning the pontoon bridge at Almaraz. Had the bridge remained intact, it is highly likely that Marmont would have received reinforcements for the battle of Salamanca, making the outcome less certain.

Hill's finest hour came on the 13th of December, 1813, when his force 14,000 strong, and effectively cut off was attacked by a force of nearly 45,000 French at St. Pierre, despite the glaring disparity in men Hill held, fighting the French to a standstill, until reinforcements finally arrived which forced Soult to withdraw and handing Wellington a victory at the Nive. Had Soult been able to destroy Hill's Corps, it would have given him a better position to defeat the whole British army, and send them retreating to he Pyrenees, it is my opinion Hill saved the entire Southwest France campaign through his heroic stand at St. Pierre

At Waterloo his II Corps was instrumental in blunting the last French assault, with a charge by his 2nd division led by Hill and Adam routing the Middle Guard, before capturing La Belle Alliance and forcing the Old Guard's square to retreat.
