Blaker won the Military Cross whilst serving as a lieutenant in the Rifle Regiment on the Western Front during the Great War.

[1] Blaker made a final appearance for Kent in the 1908 season, playing at the St Lawrence Ground against the touring Gentlemen of Philadelphia.

Wisden reports that he was an attacking batsman who scored quickly and a "fine slip fielder"[3] whilst The Times considered him "a cricketer of adventure as well as talent".

[4] Blaker captained Kent twice in 1905[10] and played once for Oxfordshire in the Minor Counties Championship and, after the First World War, for the Civil service cricket team and for his local club Blackheath.

He enlisted under the Derby scheme in December 1915 aged 36, entering the Army Reserve as a Private before being posted to 10th Battalion the Royal West Kents in March 1916.

[1] The illness kept Blaker in Britain until September 1918 when he was posted to France to join the 13th Battalion Rifle Brigade, having been promoted to lieutenant in May of the same year.

He served on the front line in the final stages of the war, taking part in the crossing of the St Quentin Canal in the Hundred Days Offensive.

[1] Blaker joined the Civil Service in April 1908 as a clerk in the Chancery Registrar's office in the Law Courts,[5] a move which brought his first-class cricket career with Kent to an end.
