Edgar William Cox
Edgar William Cox was a senior intelligence officer on the British General Staff throughout most of the First World War. He drowned in suspicious circumstances whilst swimming in August 1918 shortly after the German successes in the Spring Offensive, which drove the allied armies back a large distance. Although officially an accident, suspicions of suicide surrounded his death.
Early career
Born to George and Louisa Cox of Islington, Middlesex, in North London on 9 May 1882, Edgar Cox was educated at Christ's Hospital in Newgate and on 21 December 1900 was commissioned as a junior officer into the Royal Engineers. He came head of his class at the Royal Military Academy, Woolwich and received several awards, both there and at the School of Military Engineering. After graduation he was in December 1902 sent to the British colony of Sierra Leone to help delineate the boundary with neighbouring Liberia, with the local rank of lieutenant while there. This task occupied him until 1903, when he joined an Anglo-Portuguese boundary commission in Angola. In 1906 he left this post to conduct a three-year survey of the East Africa Protectorate. Back in Britain and serving at Aldershot barracks, he was promoted to captain, married the South African Nora and became a governor of his former school, which had by this time moved to Horsham. He also became a fellow of the Royal Geographical Society and was one of their delegates at the Paris International Map Conference in 1913.Between 1912 and 1914, Cox demonstrated a talent for staff work and was assigned to the War Office as a general staff officer, grade 3, in May 1912, gaining valuable experience in military intelligence and learning fluent French and German.
First World War
His work was good enough that in August 1914, when he was made a GSO3, he was attached to the staff of Field Marshal Sir John French, in charge of the British Expeditionary Force sent to France to counter the German invasion at the start of the First World War. In France Cox continued his staff duties under French throughout 1914 and 1915, participating in the planning and execution of several large offensives, but sharing in the reassignments at the start of 1916 following French's replacement by General Sir Douglas Haig, although he was compensated by a promotion to major later in the year. During his service on the general staff he was awarded the Distinguished Service Order and was admitted into the Legion of Honour with a Croix de Chevalier. He would later also be awarded the Belgian Order of the Crown and the Italian Order of Saints Maurice and Lazarus for his war service.Through 1916 and 1917 Cox served in the War Office as staff officer 2nd class to the Director of Military Intelligence and in January 1918 was recalled to France by Field Marshal Haig to take over his military intelligence department from Brigadier-General John Charteris. He was also given fast brevet promotions to colonel (United Kingdom)|lieutenant colonel], colonel and brigadier general to facilitate his position at this post. Within two months of his arrival, on 21 March, the Germans launched the surprise Operation Michael, which recaptured all the ground gained during the Battle of the Somme two years before and nearly drove a hole right through the allied line. Two weeks later, Operation Georgette wiped out the British advances of the Third Battle of Ypres in 1917, seemingly undoing two years of bitter fighting in one blow.
