In August 1914, on the outbreak of the First World War, Bell volunteered for the Royal Inniskilling Fusiliers, the regiment of the British Army in which his father was serving as adjutant of the 9th Battalion. He was commissioned a second lieutenant in September 1914 and was posted to the regiment's 6th Battalion. After a transfer to the 8th Battalion, he was assigned to the 9th Battalion. His two brothers, who had emigrated to the United States and Australia respectively, had also volunteered for the regiment. The 9th Battalion was part of 109th Brigade,
36th (Ulster) Division, which was sent to the
Western Front in France in October 1915. The following July, the division took part in the
Battle of the Somme. By then, Bell had been promoted to temporary
captain and was attached to the battalion's light trench mortar battery. On
1 July 1916, the opening day of the battle, he was advancing with the infantry near the village of
Thiepval towards the Thiepval Road and onto the objective, a redoubt held by German forces. When the advance in his sector was held up by a German machinegun, he made a solo foray to deal with the gunner. Further holdups were dealt with on his own through the use of trench mortar bombs. He was rallying leaderless troops when he was killed. His actions was posthumously recognised with an award of the
Victoria Cross (VC). The VC, instituted in 1856, was the highest award for valour that could be bestowed on a soldier of the
British Empire. The citation for his VC read as follows: Bell's body was never recovered so he had no known grave. Instead, his name is listed on the
Thiepval Memorial to the Missing, which was established near Thiepval in
Picardy. His brothers survived the war, although both had been wounded, and his parents died soon after the end of the war. There are several memorials to Bell's memory; he is listed on the Royal Inniskilling Fusiliers memorial in
Belfast, the King's Garden Memorial in Bootle, and the War Memorial in
Enniskillen. There is also a plaque on the former family home in Liverpool as well as a
blue plaque on the house he was born in, 1 Alma Terrace, in Enniskillen. ==Victoria Cross==
