Sydney Morgan enlisted mid-1915 and was assigned to the 2nd Light Horse Regiment in Egypt. Morgan’s unit came under attack from aircraft in October 1917. A medical officer assessed that this incident was the cause of headaches and lack of sleep which led to Morgan’s hospitalisation in November. His military record also noted he was “too nervous for work in field”. Morgan was diagnosed with neurasthenia, a now disused disorder relating to a series symptoms caused by mental distress. However, the opinion of the medical board later stated his condition was not caused by active service, but due to a nervous breakdown he had suffered in his first job after school. Morgan was transferred to the Army Pay Corp in December 1917, where he remained until returning to Australia midway through 1918.
Just prior to Morgan’s return, his name was added to the Toowoomba British Football Association honour board, having played for the Cities club. After the war, Morgan became the secretary of the Returned Soldier’s Soccer Club in 1919 and played in goal. The same year he married Winifred Slater and together they had three children.
Morgan died in 1954 aged 58.
