This little line, which comes from Bar-le-Duc, and which we have followed from Beauzée, was at the beginning of the Battle of Verdun the only one possible for victualling the troops. The main line from Châlons to Verdun was under the fire of the German artillery, and that from Bar-le-Duc or from Toul to Verdun was occupied in its centre, at Saint-Mihiel, by the enemy. The capacity of this single branch was so small that all the heroism of the defenders would have been vain, and the Germans would have entered as conquerors into the old city, if, by a remarkable feat, motors had not been able to replace the feeble railway. The road which the tourist followed on leaving Bar-le-Duc, and which he rejoined at Issoncourt, has been known since that epoch as the "Voie Sacrée" (the Holy Way). An average of 1,700 motors transporting troops, ammunition and stores, went by each day in both directions, making one vehicle every twenty-five seconds. The view below gives an idea of this line of cars winding across the country. _At the junction with N. 3, shortly after passing the spot where the railway crosses the road, turn to the right in the direction of =Verdun= (63 km.)._ This town and its entrenched camp, whose renown has become worldwide, are the subject of a special volume.
