[2][3] Tudor attended the junior school at St. Lawrence College, Ramsgate, and then joined the Royal Navy in 1915 and served as a midshipman aboard HMS Repulse.
Tudor won the Saddle at the Royal Military College, Sandhurst, which well qualified him for the British Army's cavalry.
He was then forced to leave the regiment and transferred to the 3rd Battalion, the Royal Tank Corps, based at Lydd, Kent.
