Love of horses
Before his career as an actor Edward was a gentleman jockey and rode with great aplomb both on the flat and over sticks (see references to his riding career in John Hislop's books).
The Norfolk estate is mentioned in Bill Pertwee's book about the making of Dad's Army. One of the Dad's Army episodes was by co-incidence filmed at the estate. By this time the estate was owned by the War Office and nothing was left except for the verandah and stables. As soon as John Le Mesurier arrived he realised it was familiar to him from weekend parties Edward's father had invited him to in the 1930s. So it was that Edward found himself working in a television series that featured part of his old home.
The films Wings of the Morning and The Rainbow Jacket were set in his beloved racing world, the former being set on Epsom Downs.
Finally, after his acting career he worked as a steward at Newbury Racecourse. This was described by Bill Pertwee as "fitting for a man who not only loved horses but was also an expert rider." (ibit, page 86).
On wanting to sign-up, Edward Underdown’s first approach was to the Wiltshire Yeomanry. He reputedly appeared at the depot with his friend, Sandy Carlos Clarke, a friend who had recently returned from Canada working as a ranch hand. When asked by the recruiting Sergeant to state their professions, Underdown replied, "film star" and Carlos Clarke answered, "cowboy" and thinking this was a joke, the sergeant stated that their services were not required. Underdown did subsequently join the Wiltshire Yeomanry whilst Clarke found a post with another Yeomanry regiment.
Underdown went on to have a distinguished second world war record as an officer in the Wiltshire Yeomanry serving in the 8th Army in Africa 
After the war Edward resumed his acting career but remained in the Territorial Army. He remained in the Territorial Army Reserve of Officers until is reached the age limit. He retired as Captain on 7 November 1959 and retained the rank of Honorary Major.
