When originally posted this image was described as an unidentified captain of the Essex Regiment. Thanks to site
visitor Mick Murray it has now been identified as Captain W. A. Hebden of the 1st Battalion, Essex Regiment
taken in 1899 just prior to the battalion's departure for South Africa and Boer War service. Mr. Murray provided
information that originally appeared in the 1908 book titled The 1st Battalion Essex Regiment in South Africa
1899-1902 by the then Battalion Adjutant Brevet-Major A. G. Pratt.

The book also states that Capt. Hebden died of enteric fever at De Aar, South Africa on 27th January, 1900.

The Army List of 1895 lists Wilfrid Arthur Hebden:

Lieutenant - 30 January, 1886 1st Battalion, Essex Regiment

Hebden was born February 1867. He was the son of Alfred H. P. Hebden and Alice. His father was a member of the clergy.

Above: A scan of the group photo of officers of the 1st Battalion Essex
Regiment from
The 1st Battalion Essex Regiment in South Africa 1899-1902
by the then Battalion Adjutant Brevet-Major A. G. Pratt. Captain Hebden
appears circled in red on the above photograph and in detail at left. It is
interesting to note that Captain's Hebden's collar appears with the exact same
folds and wrinkles in both this photo and the above cabinet photograph which
leads one to believe that both  images were taken at the same time and most
likely by the same photographer.
