Sir Iain Colquhoun, 7th Baronet, 29th Laird of Luss, KT, DSO & Bar, FRSE, was a Scottish landowner and British Army soldier during the First World War.
Military career
During the First World War, Colquhoun served in the Scots Guards. In 1914, the opposing troops on the Western Front had unofficially observed a Christmas truce. The following year, however, when the 28-year-old Captain Colquhoun agreed to a German officer's request for a short truce on Christmas Day, lasting about an hour, he was brought before a court-martial. He was defended by Raymond Asquith, son of Prime Minister H. H. Asquith. On 17 January 1916, he was found guilty after a five-hour trial, but received the lightest possible sentence, a reprimand. The sentence was remitted shortly afterwards by General Sir Douglas Haig, as Commander-in-Chief of the British Expeditionary Force, in view of Colquhoun's former distinguished conduct in the field. By 1918 he was Commanding Officer of 2/4th Battalion, Leicestershire Regiment in 59th Division. When the German Spring Offensive opened on 21 March 1918, the division's forward defences were quickly overrun. 2/4th Leicesters had only just come out of the line after 24 hours of continuous trench duty, but were sent straight back up to assist in the defence. The battalion could get no further forward than the rear of the Battle Zone where the 'line' was no more than a yet-to-be-dug trench marked out with the turf removed and no barbed wire. The men extended along the line even though they were completely exposed in the open. Under the inspiring leadership of Lieutenant-Colonel Colquhoun and Regimental Sergeant-Major 'African Joe' Withers, the battalion held off the Germans for the rest of the day, with modest casualties. Colquhoun was wounded during the war and awarded the Distinguished Service Order and Bar and a Mention in Dispatches. After the war he was Honorary Colonel of the 9th Battalion Argyll and Sutherland Highlanders and Glasgow University Officer Training Corps, and President of the Dunbartonshire Territorial Association.
Colquhoun was the son and heir of Alan John Colquhuon, 6th baronet, and his first wife, Justine Henrietta Kennedy. He succeeded his father as the 7th baronet in 1910, as Sir Iain Colquhoun of Luss and Chief of the Clan Colquhoun. Sir Iain married Geraldine Bryde Tennant on 10 February 1915, and they had two sons and three daughters. One of their daughters, Fiona, a Segrave Trophy winner, married the 8th Earl of Arran, an Irish peer; the present 9th Earl is their son.
