The Rhine Patrol Flotilla arrived on the Rhine in January, 1919 by way of the Seine (Le Havre to Paris), Marne (Paris to near Reims), and the Canal del la Marne au Rhin (through to Strasbourg).
A canal bridge across the Meurthe somewhere between Ligny-en-Barrois and Tronville-en-Barrois (approaching Bar le Duc on the way to Strasbourg).
