On 19th April 1953, the ship arrived at Harwich after making passage from Esbjerg, Denmark and moored at Parkeston Quay. Soon after the passengers had disembarked a fire broke out in one of the passenger cabins. Fire fighting efforts by the ship’s crew were unable to control the fire. Local fire fighting brigades arrived and provided additional assistance, however, the fire continued to rage out of control. Four local fire-fighters and two of the crew were injured while attempting to fight the fire.
