A misty panorama opens over the Rhine at Coblenz — flat-bottomed barges and a small steam tender rest in a calm harbor basin while the fortress of Ehrenbreitstein looms on its basalt crag across the river, a scene frozen in the anxious quiet of the First World War era. The sepia-toned view, labeled Rheinhafen und Ehrenbreitsteln, captures the working character of the Rhine waterfront: moored cargo lighters, a dockside shed, and the tree-lined promenade of Ehrenbreitstein village beneath the great Prussian citadel. Coblenz (modern Koblenz) sat at the strategic confluence of the Rhine and Moselle and was occupied by Allied forces from 1918–1923; this card, numbered Nr. 2 in its series and coded 17 6030, likely dates to around 1917 and may have passed through the hands of a soldier or administrator during that turbulent period.
