Born in Leicester,[3][4] Gee was orphaned when aged 9.[5] He was sent to the workhouse in Leicester, then to the Countesthorpe Cottage Homes for orphaned children. He enlisted in the Army in 1893.[6]Quartermaster-Serjeant Robert Gee was commissioned as a second lieutenant on 21 May 1915.[7][8]
He was awarded the Military Cross in for his actions on the first day on the Somme (1 July 1916); "For conspicuous gallantry in action. He encouraged his men during the attack by fearlessly exposing himself and cheering them on. When wounded he refused to retire, and urged his men on till, after being blown into the air by a shell, he was carried in half unconscious."[9]
He was 41 years old, and a temporary captain in the 2nd Battalion, The Royal Fusiliers,[10]British Army during the First World War when he was awarded the Victoria Cross, the highest and most prestigious award for gallantry in the face of the enemy that can be awarded to British and Commonwealth forces, for his actions on 30 November 1917 at Masnières and Les Rues Vertes, France, during a German counter attack in the Battle of Cambrai (1917):
An attack by the enemy captured brigade headquarters and ammunition dump. Captain Gee, finding himself a prisoner, managed to escape and organised a party of the brigade staff with which he attacked the enemy, closely followed by two companies of infantry. He cleared the locality and established a defensive flank, then finding an enemy machine-gun still in action, with a revolver in each hand he went forward and captured the gun, killing eight of the crew. He was wounded, but would not have his wound dressed until the defence was organised.[11]
He was elected MP for Bosworth at the 1924 general election.[12] He became disillusioned with parliamentary life however, and he was reported to have been absent from his political duties for over a year at the time of his resignation in 1927, having emigrated to the backwoods of Western Australia with no intention of returning.[13] The subsequent 1927 Bosworth by-election was a Liberal gain.
