During the Second World War, Clifford-Smith was a member of the
Royal Naval Volunteer Reserve. After leaving the armed forces, he married the English artist
Joan Glass (1915–2000). The couple left London for Suffolk in 1947. While in
East Anglia he painted mainly religious works much influenced by the French expressionist,
Georges Rouault. In 1952 he moved with his family to Great Bardfield in north west Essex, firstly living in ''Buck's House'', Great Bardfield. In his new home Clifford-Smith was an active member of the Great Bardfield art community during the mid to late 1950s and later became the Honorary Secretary of the group. During the 1950s the Bardfield artists included:
John Aldridge,
Edward Bawden,
George Chapman, Stanley Clifford-Smith,
Audrey Cruddas, Joan Glass,
Walter Hoyle,
Sheila Robinson,
Michael Rothenstein,
Marianne Straub, among others. The Great Bardfield Artists were diverse in style and rivalled the better known art community at
St. Ives. Clifford-Smith and the other Bardfield artists exhibited in the large 'open house' shows in the isolated village in 1954, 1955 and 1958. These shows attracted thousands of visitors and made the art community famous thanks to national press coverage and several one-off and touring shows in the late 1950s. The artists work in the 1950s was diverse and included Irish and Italian landscapes, images of ships, as well as hypnotic 'mother and child' portraits. Clifford-Smith received many positive press reviews for his work while at Great Bardfield. In 1958 the artist moved to the
Old Bakehouse in Great Bardfield. In the early 1960s the Great Bardfield art community fragmented and Clifford-Smith and his family moved to Little Baddow Hall near
Chelmsford. During his time at
Little Baddow he painted mainly thickly textured monochrome moon portraits. Following his death, the artist had several important exhibitions of his work; a retrospective at
The Minories,
Colchester (November 1969), Little Baddow Hall Arts Centre (July 1979) and at the
Fry Art Gallery,
Saffron Walden (September/October 1998). His work is included in several prominent collections including: the Benjamin Britten Foundation, Aldeburgh, Suffolk; the Beecroft Art Gallery, Southend, Essex; and Thaxted Church, Thaxted, Essex. ==Personal life==
