William Gabriel Davy commanded the 60th Rifles in the early Peninsula War. He joined them from the 61st as a Captain in 1802, and became Major in 1807; he received the Army Gold medal fro the battles of Rolica, Vimeriro and Talavera and transferred to the 7th Garrison Battalion in December 1809. He became a Knight of Hanover, a general in 1854 and was appointed colonel of the 1/60th in November 1842. He died in Gloucestershire in January 1856.

Salter studied painting under Royal Academician James Northcote from 1822 to 1827. Following his formal training he travelled to Florence where, in 1831, he exhibited his Socrates before the Judges of the Areopagos. The success of this work led to his election as a member of the Florentine Academy of Fine Arts and he held the office there of Professor of History until his return to England in 1833. He was a prolific portraitist, and many of his portraits served as preparatory works for his best-known work, The Waterloo Banquet at Apsley House (1839). He also painted religious, mythological, and historical subjects, exhibiting chiefly at the British Institution. He became a member of the Society of British Artists in 1846.
