A fifth Canadian soldier has died from injuries sustained when a fast-spreading grass fire swept through a military training exercise in Alberta last month, the Canadian Armed Forces said on Saturday.Pvt William Douglas Dal Bianco died on Friday at a hospital in Ontario, where he had been receiving treatment since the October 17 incident at Canadian Forces Base Wainwright, southeast of Edmonton.Four soldiers were killed earlier in the incident, while 24 others remain hospitalised, according to the Canadian Armed Forces.The fire broke out as troops from the 3rd Battalion, Princess Patricia’s Canadian Light Infantry, were conducting a live-fire training exercise. Strong winds caused the flames to spread rapidly towards the soldiers, catching several of them off guard.According to the BBC, 38 military personnel were injured in the incident, with 14 having been discharged from hospital by Saturday.Canadian Prime Minister Mark Carney expressed condolences over Dal Bianco’s death, saying the soldier and his colleagues had been training to defend the country.“With their bright futures still before them, they chose to safeguard ours. That is service,” Carney said in a social media post.The four soldiers killed earlier were Pvt Shaun Farrell, 23, from Prince Albert, Saskatchewan; Pvt Aidan Goulding, 23, from North Vancouver, British Columbia; Pvt Hayden Lykkemark, 19, from Langley, British Columbia; and Sgt Morgan Wong, 26, from Edmonton.The BBC reported that an initial investigation indicated the fire was likely sparked by a grenade launcher being fired at the base’s grenade range. Firefighters stationed at the base were aware of the blaze but could not immediately tackle it because the area was considered dangerous due to the possibility of unexploded ammunition.The fire reportedly spread across a kilometre within seconds, prompting an overnight firefighting operation as nearby hospitals received large numbers of injured personnel.Military police are investigating the incident, while a separate military board of inquiry will examine the circumstances surrounding the tragedy and recommend measures to prevent similar accidents.Carney had earlier described the incident as one of the worst peacetime tragedies involving Canada’s armed forces on Canadian soil.
