He had never seen it. He was working from Roman military reports, and the river he was sketching from Egypt is the same one that today runs through Lingen, Meppen and Emden under the name Ems. The Romans knew this river painfully well. They built a fort called Amisia at its mouth, hoping to use the waterway as a corridor into the Germanic tribes living along its banks — the Cherusci, the Bructeri, the Chamavi — many of whom would later coalesce into the Franks. Instead, they were stopped at the Teutoburg Forest in 9 AD in one of the worst military defeats in Roman history, and checked again six years later. The river became, in Tacitus's phrase, a road leading nowhere. Three hundred and sixty-two kilometers long. Bordered for most of its length by swamps where infantry could not stand.

Pomponius Mela had Amasius. Strabo and Ptolemy preferred Amisios or Amasios. The variations probably reflect different Latin tran...

For most of human history the river simply flowed past Emden and continued out to the North Sea through a relatively narrow channel. The Dollart bay — the broad estuarine basin into which the modern Ems discharges — did not exist before the late thirteenth century. A catastrophic...

In late July 1914, with the First World War about to begin, the Imperial German government announced plans to mine the entire Ems estuary against British warships. There was a problem: the boundary through the estuary was disputed, and mining contested water meant the Netherlands...

Ems: The Ship-Carrying River

Canals dug in the eighteenth and nineteenth centuries connected it to the Rhine system, the Weser, and the Mittellandkanal, making it a working highway of inland shipping. The Meyer Werft shipyard at Papenburg, about 50 km inland from th...

Ems: Borkum and the Two Mouths

Where the river finally meets the North Sea, the channel splits around the German island of Borkum into two straits: the Westereems on the Dutch side and the Osterems on the German. Both still carry the river's name. From the dunes of Borkum on a clear day you can see Schiermonni...
