On 10 September 1914 Ernest Attwater’s attestation papers were formally approved by a major in the Royal Sussex Regiment. He had been medically examined at Haywards Heath (where he had been a member of the local Territorial Force company for three years prior to his move to London from Cuckfield) as early as 5 September, and had then completed the attestation papers at Chichester on 9 September. He was posted to 9th Battalion, one of the newly raised battalions of Kitchener’s New Army. He became Private 3305, but with his prior TF experience it’s no great surprise that he was promoted lance corporal as early as 12 October (NCOs were in short supply). He stated his age as 25 years, 220 days, and gave his occupation as carpenter and pro cricketer (he was on Surrey’s ground staff at the Oval).
It’s possible his brother Frank Norman joined up at the same time, but as he ended up in 3rd (Special Reserve) Battalion, it’s not absolutely clear (and his papers do not survive). Certainly both brothers were serving by 30 October when The Ringing World reported that Frank Norman was at Dover with 3rd Battalion, and Ernest was at Shoreham with 9th Battalion.
