Aged 19 on the outbreak of the Second World War, Jamieson was considered too young for overseas service and did not initially go with the battalion, now part of the 51st (Highland) Infantry Division, to join the British Expeditionary Force (BEF) when it went to France in 1940 but followed later.

On 7/8 August 1944, south of Grimbosq, Normandy, France, Jamieson was in command of D Company, being the only officer remaining, which had established a bridgehead over the River Orne.

The citation for Captain David Jamieson in the London Gazette of 26 October 1944 ends: ...Throughout the thirty six hours of bitter and close fighting and in spite of the pain of his wounds, Captain Jamieson showed superb qualities of leadership and great personal bravery.

He personally was largely responsible for the holding of this important bridgehead over the River Orne and for the repulse of seven German counter-attacks with great loss to the enemy.

[5]Following the war, he worked for the Australian Agricultural Company, which ran several sheep and cattle stations; he became a director in 1949 and was Governor from 1951 to 1975.

David Jamieson's Victoria Cross is displayed in the Royal Norfolk Regimental Museum in Norwich Castle.
