[2] Horlock was a 28 years old Bombardier in the 113th Battery, Royal Field Artillery, British Army during the First World War[1] when he performed the service for which he was awarded the Victoria Cross.

[2] Horlock joined the Royal Field Artillery as a regular soldier in 1904 and for an unknown reason served as Harlock, possibly due to a clerical error on enlistment papers and subsequent records.

[5] On the morning of 30 December Aragon was no more than 10 miles (16 km) from her destination at the Port of Alexandria in Egypt when the German submarine SM UC-34 torpedoed her, sinking her within 20 minutes.

[2] On 24 May 2001 (previously called Empire Day) a memorial to E.G. Horlock, VC was unveiled in St John's parish church, Langrish, Hampshire.

There was a display in the nearby Assembly Rooms and, later in the day, the firing of an 18pdr field gun (similar to the type Horlock would have served with) in Anstey Park.
