Baron Trevenen James had been a mathematical scholar and head of his House at Harrow; in 1907 he passed into Woolwich, and two years later was commissioned in the Royal Engineers. He was early interested in aviation; in June 1912, after only three days' practice, he obtained the Royal Aero Club certificate at Hendon, flying a Howard Wright biplane. In April 1913 he joined the Military Wing of the Royal Flying Corps, and was at once employed in carrying out experiments with wireless. In December 1913 he was joined by Lieutenant Lewis, and the two became famous for the theory and practice of their craft. On the outbreak of war Lieutenant James was attached to No. 4 Squadron for wireless duties; when in September 1914 the headquarters wireless telegraphy unit was formed, under the command of Major H. Musgrave, at Fere-en-Tardenois, Lieutenant James was attached to it, and shared with Lieutenant Lewis the duty of reporting by wireless over the fire of the enemy guns. Like Lieutenant Lewis, he was subsequently killed in the air. On the 13th of July 1915 his commanding officer reports: 'He was observing from the aeroplane alone, as he generally did. He was ranging a battery, and was being heavily shelled. His machine was hit by a shell, and was seen to dive to the ground from a great height. The Germans dropped a note from one of their machines saying that he was dead when he fell.... He met the end I am sure he would have wished for--if it had to be--suddenly, alone, and doing his duty.' These two, then, Lieutenants Lewis and James, had been untiring in their enthusiasm and perseverance during the years before the war. On the Aisne their reward was granted them. 'I wish to express', says General Sir Horace Smith-Dorrien in a telegram dated the 27th of September 1914, 'my great admiration for the splendid work the Royal Flying Corps is doing for my Corps from day to day. Nothing prevents them from obtaining the required information, and they frequently return with rifle or shrapnel bullets through their aeroplane or even their clothing, without considering such, to them, ordinary incidents as worth mentioning. To-day I watched for a long time an aeroplane observing for the six-inch howitzers for the Third Division. It was, at times, smothered with hostile anti-aircraft guns, but, nothing daunted, it continued for hours through a wireless installation to observe the fire and indeed to control the Battery with most satisfactory results. I am not mentioning names, as to do so, where all are daily showing such heroic and efficient work, would be invidious.' Lieutenants Lewis and James are now beyond the voices of envy, and their names may fitly be recorded in the memory of their country. One of the earliest of the messages sent down by wireless from the air is dated the 24th of September 1914. It is worthy of full quotation:
