1915 Vancouver bridge arson attack
The Vancouver bridge arson attack took place on April 29, 1915, when two key bridges in the West Coast Canadian city of Vancouver, Granville Street Bridge and Connaught Bridge, were set on fire. Background
The Connaught Bridge was completed in 1911 for $740,000, opening to traffic on May 24, 1911. The following year, Canada's Governor General, the Prince Arthur, Duke of Connaught and Strathearn, accompanied by the Duchess and their daughter, Princess Patricia, visited Vancouver to officiate at a ceremony renaming the new crossing as the "Connaught Bridge" on September 20, 1912. The name "Connaught" never caught on, and most people continued to call it simply the "Cambie Street Bridge", after the street that runs across it, Cambie Street, named for pioneer Vancouver resident Henry John Cambie. Fire
The fires happened on April 29, 1915. The American media widely reported that the fires were set by German immigrants celebrating the Imperial German victory over the Canadians at Ypres, Belgium. The fire on the caused a  span of the Connaught Bridge to collapse and caused about $90,000 in damage. Arrests
Four Germans were arrested and interned Baron von Luttowitz (related to the Imperial German Kaiser), Dr. Otto Grumert, Paul Koop and Frederich Spritzel. See also
