 Early life
James Cornwall was born in India, only son of James Cornwall, the Postmaster General of United Provinces and his wife Agnes Hunter.
Cornwall went to Rugby School and the Royal Military Academy, Woolwich. Commissioned into the Royal Field Artillery in 1907, during his first spell of annual leave he travelled to Germany to study German. He later passed the Civil Service Commission examination as a first-class German interpreter, the first of the eleven interpreterships he was to gain. He passed as first-class interpreter in French, Norwegian, Swedish, Hollander Dutch, and Italian.
On the outbreak of World War I Cornwall joined the Intelligence Corps at Le Havre. In 1915 he was appointed to the rank of Captain at 2nd corps headquarters in the Second Army. In 1916 he was promoted to temporary major at the general headquarters of the British expeditionary force, under Sir Douglas Haig. In 1918, Cornwall was posted to the War Office as head of the MI3 section of the military intelligence directorate, where he remained until the armistice. He was decorated with the Military Cross in 1916 and the Distinguished Service Order in 1917.
In 1919, Cornwall was sent to the peace conference in Paris, where he worked with Reginald Leeper and Harold Nicolson on the new boundaries of Europe. Several jobs in the Middle East in the 1920s gave him the opportunity to study Turkish and modern Greek.
In 1927, Cornwall was sent to China with the Royal Artillery (Shanghai Defence Force), to protect British life and property in the Shanghai International Settlement. This enabled him to learn Chinese and to travel extensively in the Far East with his wife.
From 1928 to 1932 he held the post of military attaché in Berlin. In 1934, after two years as commander of the 51st Highland division, Royal Artillery, based at Perth, Scotland, Marshall-Cornwall was promoted major-general. He spent the next four years travelling in Europe, India, and the United States, then two years in Cairo as head of the British military mission to Egypt. Here he qualified as an interpreter in colloquial Arabic.
In 1938, he was promoted to lieutenant-general, in charge of the air defence of Great Britain. In May 1940 he went to France to help evacuate British troops from Cherbourg, boarding the last ship to leave the port. He took over command of III Corps in England in June 1940 holding the post until November 1940. In 1941 he was sent by Winston Churchill to Turkey in an attempt to persuade the Turks to join the war, a mission which failed.
Marshall-Cornwall took over Western Command in November 1941, but was dismissed in the autumn of 1942 for going outside the proper channels to secure the safety of the Liverpool docks. He spent the rest of the war with the Special Operations Executive and MI6, attempting to promote better relations between them. He retired from the army in 1943.
 Personal life
Cornwall met Marjorie Coralie Scott Owen, who was driving an ambulance for a Red Cross mission to White Russian refugees, while encamped in the Izmit peninsula. They were married in Wales in April 1921. In 1927 he inherited a small estate in Scotland from his uncle William Marshall, on condition that he should assume the surname of Marshall. As Marshall was one of his forenames, this was achieved by the insertion of a hyphen. The Marshall-Cornwalls had a son and two daughters. Their elder daughter died aged fourteen in 1938 after an operation for appendicitis in Switzerland. Their son was killed in France in 1944. He is buried on the spot where he fell in a Normandy orchard, purchased by Marshall-Cornwall to protect his son's grave. His other daughter Janet married Digby Willoughby, 12th Baron Middleton in 1947.
