Lieutenant-General Sir Thomas Picton MP (1758–1815)

Picton was the highest-ranking allied casualty at Waterloo and one of two MPs to be killed during the battle. The younger son of a Welsh country gentleman, he was a career soldier who became Wellington's right-hand man in the Peninsula and was frequently thanked by Parliament for his military achievements. He gained a seat in the Commons, and supported Lord Liverpool's Tory administration when able to attend.

An impetuous and courageous officer, he was badly wounded at the Battle of Quatre Bras on 16 June, but he kept his condition secret, and led the 5th Division at Waterloo two days later, when he was shot dead. Wellington wrote that ‘he fell gloriously leading his division to a charge with bayonets, by which one of the most serious attacks made by the enemy on our position was repulsed'.
