Flags were laid at the graveside this week for a volunteer firefighter and his trusty dog to remember their heroism made more than a 100 years ago. Wilmington Fire Department shared the duo’s story Wednesday, marking the anniversary of a deadly fire that happened 139 years ago in downtown Wilmington. In the late evening of April 10, 1880, a fire started at George Peck’s store at the corner of Front & Dock streets. Captain William Ellerbrock, a tugboat captain and volunteer fireman with the Howard Relief Fire Company, joined others in an effort to contain the fire. Before fighting the fire, Ellerbrock asked a bystander to hold his dog, Boss, who went everywhere with the captain.
