The Mittelland Canal was opened and connected central Germany with the Rhine via the Rhine-Herne Canal. The volume of freight on German waterways continued to grow steadily, not least due to the materials and equipment required by the German army in its war of attrition on the Western Front.
The two companies "Badische Actiengesellschaft für Rheinschiffahrt und Seetransport" and "Rheinschiffahrts Actiengesellschaft" set up a joint company on 13 November. The name they chose for the new company was the Latin word for the river that would carry their hopes and expectations from then on - "Rhenus", the Rhine. The company was entered in the commercial register as Rhenus Transport GmbH with its head office in Frankfurt. Branch offices were established in Mannheim, Mainz, Antwerp and Rotterdam at the same time.
