Balfour Halliday and his parents, John & Jemima, lived at 13 Victoria Avenue, Cheadle Hulme. He attended the parish church and was a member of the local Church of England Mens' Society. He worked at the Stockport branch of the Manchester & Liverpool District Bank and in his spare time played lacrosse for Cheadle Hulme.
In 1911, he had joined the part-time Cheshire Yeomanry as a private and volunteered for overseas service when war was declared. The history of the Yeomanry records a Sergeant B Halliday who, in November 1915, was one of two men who "gave up pending commissions, in order to go abroad with the Regiment". The Yeomanry was a Territorial cavalry unit and would see action in Egypt. It later fought as dismounted cavalry and, in early 1917, was merged with the Shropshire Yeomanry and became a battalion of the Shropshire Light Infantry.
Around this time, he was invalided home suffering from fever. He subsequently trained for a commission. He was gazetted in early June 1917 and had a brief period of home leave before being posted to the front.
Lieutenant Halliday joined his new battalion towards the end of June 1917. On 1 July, the Battalion went back into the trenches after a period in reserve, in the area of Fauquissart. This hamlet is approximately half way between the towns of Bethune and Armentieres in Northern France (along the present D171 road). He would only spend three days in command of troops in the front line before he was killed. The Battalion War Diary states "Nothing to report" for the 1 July. The same entry is made for 2 July. But it reports that at 1am on 3 July, there was an "intense hostile bombardment of our front line with trench mortars and guns of various calibres lasting for 1¼ hours and causing 13 casualties (including one officer died of wounds)".
Balfour will have been evacuated from the trench and received immediate first aid at an Advanced Dressing Station just behind the front line. From there he would have been taken for medical treatment to 54th Casualty Clearing Station, operating some 5 kilometres to the north west at Estaires. His wounds must have been very severe and he did not survive. Balfour is buried in the cemetery next to where the Station was operating.
