After the outbreak of the Second World War he was a founding member of the 151st Battalion of the Parachute Regiment in India.

After returning to England he was made second in command of the 11th Battalion, Parachute Regiment in 1944, shortly before flying to Arnhem with the rest of the 4th Parachute Brigade and 1st Airborne Division. Here he again served with distinction during the Battle of Arnhem, and despite being wounded he took command of a mixed force that successfully defended the Allied perimeter against repeated German attacks. He was awarded the Distinguished Service Order (DSO) twice, for his actions in Sicily and Arnhem. After the war Lonsdale remained with the army and took command of the 3rd Parachute Battalion.
