Lt Col. William Miller of the 1st Regiment of the British Foot Guards of Glenlee was mortally wounded at Les Quatre Bras at the age of 31 on 16 July 1815 and died at Brussels the following day. Upon finding himself in such a vulnerable state, he sent for his close friend, Lt Col. Thomas;
"Thomas, I find that I am mortally wounded; I am pleased to think that it is my fate rather than yours, whose life is involved in that of your young wife." After a pause, he said faintly, "I should like to see the colours of the regiment once more before I quit them forever." They were brought to him, one wound around his wounded body. His countenance brightened, he smiled, and in declaring himself satisfied, he was then carried from the field.
The friend, Lt Col. Thomas, was sadly killed the following day. His widow, who resides in the portrait, sits by the window in mourning, the silhouette of her husband's close friend, attached below to the frame. She is described in The Waterloo Roll Call as having been left in disturbed circumstances, but she subsequently became the 1st wife of Lord Lyndhurst.
