Ted Todhunter was born on his family's estate of Kingsmoor House and Stewards farm in Great Parndon, Essex. He attended Rugby School, becoming a Cadet in the O.T.C division. In 1922 he was Gazetted as 2nd Lt. in the 104th Brigade, Royal Field Artillery, rising to Lieutenant-Colonel.
During the Second World War, he served as a brigadier with the Royal Horse Artillery and was captured along with General Gambier-Parry by Italian forces at Mechili in Cyrenaica, North Africa in April 1941. He was initially taken to the same barracks as Major-General Sir Adrian Carton de Wiart, VC in Tripoli after which he was taken by ship to Naples and then on to the Villa Orsini near Sulmona. There he helped in the garden and ‘collected news from Italian newspapers, making a resume of them in English which he managed brilliantly’. He was transferred in April 1942 to Castello di Vincigliata, which was a medieval castle near Florence for very high ranking officers. Amongst the captives were Major-General Sir Adrian Carton de Wiart VC, Air MarshalOwen Tudor Boyd, Lieutenant General Sir Philip Neame VC, Lieutenant-Colonel John Frederick Boyce Combe, General Sir Richard Nugent O'Connor and Daniel Knox, 6th Earl of Ranfurly, known as 'Dan' Ranfurly. He took on the role of camp librarian, which by the Spring of 1943 numbered nearly one thousand books. He was part of the tunnelling group that worked in shifts for over six months. The escape was successful - six officers escaped of which two managed to make Switzerland, New Zealanders Brigadiers James Hargest and Reginald Miles. He himself was able to escape during the Italian Armistice in September 1943 with the remaining officers and men. They branched off into the mountains, seeking refuge in the Monastery of Camaldoli. ‘He discovered a retired Dutch diplomat, close by, and he and O’Connor used to listen to the news on their wireless’. He joined the Italian partisans known as the Garibaldi Brigade Romagna under the leadership of Libero Riccardo Fedel, who during the winter of 1943/4 helped dozens of allied prisoners to escape. By May 1944 he reached Allied lines in Ancona by fishing boat with Guy Ruggles-Brise, John Combe, Dan Ranfurly and an American pilot named Jack Reiter. He was flown to Algiers, from where he and John Combe were flown back to England.
