Louise, Lorne, and two attendants, were hurt in a sleigh accident on 14 February 1880. The winter was particularly severe, and the carriage in which they were traveling overturned, throwing the coachman and footman from the sleigh. The horses then panicked, and dragged the overturned carriage over more than of ground. Louise was knocked unconscious when she hit her head on the iron bar supporting the roof, and Lorne was trapped underneath her, expecting "the sides of the carriage to give way at any moment". Eventually, as they overtook the sleigh ahead, the horses calmed, and the occupant of that sleigh, Princess Louise's aide-de-camp, ordered an empty carriage to convey the injured party back to Rideau Hall.
