Major Sir Alexander George Woodford, GCB, KCMG
Commander of the II/2nd Foot Coldstream Guards
During the Hundred Days, Woodford commanded the 2nd battalion of the Coldstream Guards at the Battle of Quatre Bras, the Battle of Waterloo and the storming of Cambrai in June 1815. During the closing stages of the Battle of Waterloo, Woodford fought his way into the Château d’Hougoumont, one of the key landmarks on the battlefield, and then took command of it as the Duke of Wellington ordered a general advance on the French. Woodford was appointed a Companion of the Order of the Bath on 4 June 1815 and a Knight of the Austrian Military Order of Maria Theresa on 2 August 1815. He remained in command of his battalion when it formed part of the Army of Occupation of France.
In my opinion this site is the best source of uniform reference for the 100 days (Waterloo) campaign:
