After the Ashanti campaign Aspinall was granted a regular commission as a Second lieutenant in the Royal Munster Fusiliers (RMF) backdated to April 1900 but did not join until October 1900.^[9][10] He was seconded for service with the Army Service Corps in the Second Boer War, and served with it in operations in Cape Colony from August to December 1901 and in Orange River Colony from February to May 1902.^[11] He was promoted to lieutenant in the RMF on 6 February 1902.^[12]

He was promoted to Captain on 2 August 1908 and having passed staff college he served as a staff captain and General Staff Officer Grade 3 (GSO3) at Army Headquarters in India for four years from 26 January 1909. From 1 October 1913 he was at the War Office in London as a GSO2.^[13]

On the outbreak of World War I Aspinall was working as a GSO2 under the Director of Staff Duties at the War Office.^[14] In March 191, he was informed that he would be joining the staff of Sir Ian Hamilton's Mediterranean Expeditionary Force. He was one of Sir Ian Hamilton's most trusted aides during the Gallipoli campaign (1915–1916), where his actions saw him mentioned in despatches over a dozen times.^[15] On 7 August 1916 he was appointed chief of staff (GSO1) of the 63rd (Royal Naval) Division, involved in the final phase of the Somme operations and the at Arras and Ypres in 1917.^[16] On 18 November 1917, Aspinall moved up to be Brigadier-General General Staff of VIII Corps and remained in this role for the remainder of the war. ^[17]

Aspinall retired from the Army in 1920 and was employed by the Historical Section of the British Committee of Imperial Defence, researching and writing the text of several volumes of the British History of the Great War.^{[citation needed]}
