Spencer Ewart

Lieutenant General Sir John Spencer Ewart, KCB (1861–1930) was a British Army officer who became Adjutant-General to the Forces .

Educated at Marlborough College and the Royal Military College, Sandhurst, Spencer Ewart was commissioned into the Queen's Own Cameron Highlanders in 1881.

He served with his regiment in Egypt and fought at the Battle of Tel el-Kebir in 1882. He was also involved in the Nile Expedition in 1884 and served with the Sudan Frontier Field Force from 1885 to 1886. He served as a staff officer in the Second Boer War in South Africa, and returned to the United Kingdom after the end of that war in July 1902. The Commander-in-Chief in South Africa, Lord Kitchener, wrote in a despatch in June 1902 how Ewart was "a Staff officer of considerable ability. He has rendered good service in connection with the distribution and movements of troops."

In 1904 he was appointed as Military Secretary and in 1906 moved on to be Director of Military Operations at the War Office. In 1910 he was appointed Adjutant-General to the Forces: he resigned in March 1914 over the Curragh Incident when British officers stationed at the Curragh Camp near Dublin made it clear that they would not want to march against Ulstermen in the north. He was appointed General Officer Commanding Scottish Command in 1914, a post he held until 1918: he retired in 1920.

Ewart was an Aide-de-Camp General to King George V from 1910 to 1914.
