Apsley House, London. Major Generals Sir Frederick Ponsonby (1783-1837) and Sir Colin Campbell (1776-1847) sketched by Jan Willem PIENEMAN in 1821 (WM 1468-1948). Both served at the Battle of Waterloo in 1815. Ponsonby was Colonel of the 12th Light Dragoons and was severely wounded following a charge to support the withdrawal of the Union Brigade. Campbell was commandant at Allied headquarters and (other than Wellington) was the only man on the general staff to survive the battle uninjured.
