Regimental records published after the War indicate that Jubal had been born in Manchester and he enlisted into the army there in August 1914.
His parents lived at Fields Farm in Woodley, presumably farming the land as tenants. Jubal, however, worked as a chauffeur to a Mr Morley in Edgeley. It would seem that his mother was anxious for him to stay at home and not volunteer for the army as the local newspaper reported that he had said to her "You wouldn't have me for a coward, would you?"
He will have gone overseas on active service in the spring of 1915, possibly joining the Battalion after it had gone into action at Gallipoli. Shortly after arriving at the peninsula, he received a minor wound but soon rejoined his unit.
Jubal would be killed in an attack that was later officially designated as the Battle of the Vineyard. At 8.10am, British and French artillery opened a bombardment of the Turkish trenches near to Krithia Nullah. At 9.40, the infantry attacked, dashing across No Man's Land. They quickly captured the Turkish front line trench and some of the men were able to push on towards the second line of trenches. However, enfilade fire and superior numbers forced them back to the captured trench. At about 11am, the Turks counter-attacked retaking part of the line, but the Fusiliers still held most of the Vineyard. Another counter-attack at 1.30pm was broken up by Allied artillery fire, causing heavy casualties to the bunched-up Turkish troops. The History of the 42nd Division records "The Turks suffered severely in counter attacks upon the Vineyard and for some hours gave up the attempt in this quarter, but resumed it late at night with no more success."
The Fusiliers would hold the position until they were relieved on the 9th. The War Diary notes that they were "thoroughly worn out" and that out of an initial strength of 410 men, only 139 answered the roll call. The rest were dead, wounded or missing.
