1915_Vanceboro_international_bridge_bombing--Franz_Von_Papen

The 1915 Vanceboro international bridge bombing was an attempt to destroy the Saint Croix-Vanceboro Railway Bridge on February 2, 1915, by Imperial German spies.
This international bridge crossed the St. Croix River between the border hamlets of St. Croix in the Canadian province of New Brunswick and Vanceboro in the U.S. state of Maine. At the time of the sabotage attempt in 1915, the bridge was jointly owned and operated by the Canadian Pacific Railway (reporting mark CP) on the Canadian side and the Maine Central Railroad (reporting mark MEC) on the American side.
The bombing was masterminded by then spymaster Franz von Papen and executed by Werner Horn. The bomb failed to destroy the bridge but made it unsafe to use until minor repairs were done. The explosion did however blow out windows in nearby buildings in St. Croix and Vanceboro.
