After his education in 1903, he entered the service of The British Insulated and Helsby Cables Ltd of Prescot. By 1906 he had been promoted to Resident Engineer and supervised the “extra high tension” distribution system for the Cleveland and Durham Electric Power Company as well as other major works on tramways and electric power distribution.
Outbreak of war
When war was declared in 1914 he relinquished his appointment to serve in the Army. His Battalion was among the first of the Territorial units to be ordered to France and he crossed the Channel on 20 September 1914. His Battalion joined the Indian Corps to help strengthen their position along the line north of Givenchy. After repeated advances, the German troops succeeded in establishing their trenches only 50 yards from the line held by the Indian Corps.
In November 1914 his Battalion was transferred to the 3rd Division under the II Corps to help the embattled 1st and 2nd Divisions south of Ypres. By the end of November, his Battalion took their turn on duty in the trenches. Bitter trench-warfare ensued but ceased temporarily during winter and they were put to work improving the defences.
By March 1915 Hoyle received a promotion and was appointed Lance-Sergeant. On 5 April 1915 Hoyle’s Division was in the line north of Kemmel. Having arrived at the point of line to be held by his Company he superintended the movement of his men into the bays. Hoyle had just begun to speak to his brother, Leonard Arthur Hoyle (AMIEE) also serving in his Battalion when the enemy opened fire. He was hit in the chest by a rifle bullet and died moments later. Lance-Sergeant Edgar Hoyle became a Student Member of the IEE in 1902 and an Associate Member in 1910. He died aged 31 survived by his widow and their young daughter, born only a few weeks before he enlisted in the Army.
