Born on 6th June 1889 in Staines, Middlesex, Second Lieutenant Walker was killed whilst leading his men at the Battle of Festubert on 17th May 1915. He was 26.

He was the youngest son of the late Henry John Cureton Walker (b. 1841), a civil servant and Catherine Jane Walker (nee White, b. 1842), from Surrey. His Grandfather, Henry Walker was a Clergyman. He had two brothers, Henry Edward (b.1875) and William (b.1883) and three sisters, Marian Elizabeth (b.1872), Katherine (b.1874) and Mary Agnes (b.1876).

He followed his elder brother, William to Saint Ronan’s, arriving in 1899 where he was placed in Class IV.

He won prizes for Scripture Knowledge and Catechism in 1900 and 1901 respectively.

A keen athlete, in 1901 Archdale won the Junior 100 years, Junior High Jump and Junior Long Jump. The Ronian described his success as “an excellent performance for so young a performer”. He was awarded his Cricket Colours in the same year and also participated in the Christmas entertainment, taking part in the Musical Drill for the play.

In 1902 he won a prize for his Sunday Work and was employed as a server in the Grub Shop. He was also appointed Prefect and was on the Athletics Committee.

Archdale was confirmed in March 1903 by the Bishop of the Diocese, Dr Ernest Wilberforce. In April, he won the Rountree Cup for best all round athletics competitor. He won the Senior 100 Yards (by five feet), the High Jump (3ft 10¾in), the 100 Yards Hurdles and the 440 Yards Senior Race. He was also presented with a cricket award for the best averages in batting and bowling.

He left Saint Ronan’s in 1903, following his brother William to Haileybury. The Ronian recorded his departure:

“A. G. Walker, has passed the entrance Examination for Haileybury. We have had a very pleasant nine years’ association with the name of “Walker”, and we unfeignedly sorrow at the parting with “par nobile fratrum”. “A.G.” will have been with us four years at the end of this term. He also by his departure will greatly weaken our Cricket and Football Elevens.”

At Haileybury Archdale was in Melville House until his departure in March 1905. He was keen on all sports and was in the first XI for cricket, alongside his former schoolmate, Neville Bostock.

At the outbreak of the War, in August 1914, Archdale was gazetted to the North Staffordshire Regiment, 4th Battalion as a Second Lieutenant. In March 1915 he went to the Front to join the Royal Scots Fusiliers, 2nd Battalion. He would have been serving with this particular Battalion at the same time as another old Ronian, Lieutenant Cecil Raymond-Barker.

Second Lieutenant Walker would have seen action at Neuve Chapelle (10th-12th March 1915) and Aubers Ridge (9th-10th May 1915). It is believed that he was killed leading his men during the Battle of Festubert (15th-25th May 1915).

He is also commemorated on the Wiveliscombe War Memorial in Somerset where he was resident when he died.
