On 22 Jul 1812 the Battle of Salamanca was fought at which an Anglo-Portuguese army under the Earl of Wellington (age 43) defeated Marshal Auguste Marmont's French forces at Arapiles.

Brother General Thomas Bradford (age 34) and Lieutentant-Colonel Henry Hollis Bradford (age 31) fought.

Major-General John Le Marchant (age 46) was killed in action. Wellington is reported as saying to Le Marchant that he must take the first favourable opportunity to engage the enemy's infantry, "You must then charge at all hazards" was his final instruction. Following up the attack of the 5th Infantry Division Le Marchant led the 3rd and 4th Dragoons and the 5th Dragoon Guards in what was probably the most destructive charge made by a single brigade of cavalry in the whole Napoleonic period. The left wing of the French army were on the point of being defeated by the 3rd and 5th divisions of Anglo-Portuguese infantry when Le Marchant's dragoons charged in and destroyed battalion after battalion. Many of the French infantrymen sought the protection of the British infantry to escape the sabres of the dragoons. Le Marchant, knowing he had achieved a magnificent success, was leading a squadron against the last of the formed French infantry when he was shot and his spine broken.
