On his return to Britain, Macklin gained a commission as a temporary lieutenant in the
Royal Army Medical Corps (RAMC), with effect from 22 November 1916. He was promoted to temporary captain on 22 November 1917. During World War I he served in France, Russia and Italy. He won the
Military Cross (MC) for bravery in tending the wounded under fire while serving in Italy. After the war, Macklin continued to serve with the RAMC, seeing service with the Allied Expeditionary Force in Northern Russia along with his old Boss, Shackleton. He rose to the acting rank of major on 4 May 1919 and, for his service in Russia, was appointed an
Officer of the Order of the British Empire on 11 November 1919 and awarded the Russian
Order of Saint Stanislaus. He resigned his commission on 23 March 1920, retaining the rank of captain. Together with former
Endurance crew members
Worsley,
Hussey,
Wild,
McIlroy,
Kerr,
McLeod and
Charles Green, Shackleton invited Macklin to join him for the
Shackleton–Rowett Expedition in 1922 on board the
Quest. The ship was plagued by engine trouble and eventually diverted to
Rio de Janeiro. After repairs lasting several weeks, the Quest headed for South Georgia. Shackleton was troubled with heart pain throughout the voyage, but despite Macklin's orders refused to rest. In Rio, Shackleton suffered a heart attack but would not let Macklin examine him. The ship landed in South Georgia on 4 January 1922. Early in the morning of 5 January, Macklin was called to Shackleton's quarters to find him having another heart attack. He died shortly after Macklin arrived. As the ship's surgeon, it was Macklin's role to prepare the body for burial on South Georgia. In 1925 Macklin relocated to
Dundee and began work at the
Dundee Royal Infirmary, where he would work for the next 21 years. At the start of World War II, he returned to active service as a major in the Medical Corps, serving in East Africa and rising to lieutenant-colonel. He received the
Territorial Decoration (TD), and retired from the army in August 1948 with the honorary rank of colonel. He married Jean in 1947 and moved to
Aberdeen where he worked as the physician of student health services at the
University of Aberdeen. Though he retired from university practice in 1960, he continued to work at the
Aberdeen Royal Infirmary as a locum house surgeon. He and Jean had two sons, Alexander and Richard. He died on 21 March 1967. == References ==
