Son of John Baillie Buchanan-Baillie-Hamilton J.P., D.L., and Katherine, (nee Buchanan of Arnprior) of Callender, he entered Mr. Toye’s House (Moberly’s) from Mr. W. B. Gray’s school close to his home. He stood on Dress for O.T.H. XV in 1894.
Soon after the outbreak of the South African War he joined the City Imperial Volunteers and took part with them in the final advance on Pretoria. In 1901 he was transferred to the Regular Army, receiving his commission in the Seaforth Highlanders and from 1902 to 1906 was employed with the West African Frontier Force, serving with them in the Kano Sokoto campaign of 1903.
He was promoted to Captain in 1911, having been Adjutant of the Territorial 6th Battalion, Black Watch since March that year. He relinquished that in March 1914 and returned to his own regiment which was out in India at the time.
He went to the front at the beginning of the war with the 1st Battalion Seaforth Highlanders, and was mentioned in one of Lord French’s earliest Despatches. He fell near Festubert on May 9th 1915 during the Battle of Aubers.
Buchanan-Baillie-Hamilton is commemorated by Special Memorial 3 of the Woburn Abbey Cemetery, Cuinchy (the cemetery is named after a house on its east side which was used as a dressing station and headquarters.) Such memorials are erected to those whose bodies are believed to be in the cemetery, but which cannot be definitely located.
Captain Buchanan-Baillie-Hamilton married in 1905 Miss Ina Erskine McNeill. In November 1915 his sword was presented to his friend Robert Horn (7th Batt. Seaforth Highlanders, killed in action 18th April 1918 – see individual entry).
