William Wilbur Johnson was born in Wingham, Ontario, Canada, on 25th August 1889, and was the son of John and Barbara Johnson. Little information is available about his early life, but he found work as a saddler when he finished his schooling.
In his free time, William volunteered in the 20th Border Horse Regiment. When war broke out in Europe, he was called upon to play his part, and joined the Canadian Expeditionary Force. His service records confirm he was 5ft 8ins (1.73m) tall, with brown hair, blue eyes and a dark complexion. He was also noted as having two scars both on his inner left forearm.
Private Johnson arrived in England in May 1916, and was initially billeted in Shorncliffe, Kent. He did not remain in Britain for long, however, and, assigned to the 2nd Brigade of the Canadian Field Artillery, he arrived in France on 1st June 1916. William would have been in the thick of things, caught up in the bloody stalemate of the Somme for most of the rest of the year.
In November 1916, William was promoted to Acting Bombardier. After a miserable winter on the Front Line, he became ill, and was admitted to a field hospital for a week with bronchitis and influenza. He recovered and remained on the Western Front during 1917, fighting at both Vimy Ridge and Passchendaele.
By the end of November 1917, Acting Bombardier Johnson’s health was suffering once more. He became jaundiced and, after some time spent in a field hospital, he was medically evacuated to Britain for further treatment. He was admitted to the Bath War Hospital in Somerset, with what turned out to be cirrhosis of the liver. This was something his body was unable to overcome: William passed away on 29th January 1918, at the age of 28 years old.
With all of his family overseas, it was not practical for the body of William Wilbur Johnson to be returned to Canada. Instead, he was laid to rest in the sweeping grounds of the Locksbrook Cemetery, not far from the hospital in which he had breathed his last.
