Dortmund-Ems Canal
The Dortmund–Ems Canal is a 269-kilometre (167 mi) long canal in Germany between the inland port of the city of Dortmund (51°31′30″N 7°26′40″E / 51.52500°N 7.44444°E) and the sea port of Emden. The artificial southern part of the canal ends after 215 kilometres (134 mi) at Herbrum lock near Meppen. The route then takes the river Ems for 45 kilometres (28 mi) to Oldersum lock. From there, the canal continues along a second artificial segment of 98 kilometres (61 mi). This latter section was built because inland ships at the time of the construction of the canal were not built for the open sea, which they would have faced at the Dollart and the entry to the sea port of Emden. It is connected to the Ems-Jade Canal from Emden to Wilhelmshaven.
The canal was opened in 1899 to reduce demand on the railway network, which could not cope with the transport of products from the Ruhr area. Also, the canal was supposed to make coal from the Ruhr area more competitive compared to imported English coal. Furthermore, the steel industry in the eastern Ruhr area needed to import ore from abroad.
The canal was attacked numerous times during World War II due to its strategic importance. An attack in September 1943 by 617 Squadron RAF (the "Dambusters") was unsuccessful and costly. The squadron attacked it again in September 1944 using Tallboy "earthquake" bombs breaching it and causing considerable damage. It was repaired after the conflict.
