This sketch represents a set of maps scale 1/200,000 on which the Staff-major of the 20th Corps used to trace the line each day.
By strengthening the two lines of July 15th and November 2nd, which are accurately reproduced, and by adding a few lines inside and the point of the helmet, a draughtsman of the Staff-major obtained this curious figure of Germany brought to her knees.
From the plan one can easily recognise the salients of Ypres and Arras, the indentation of Montdidier, and that of Château-Thierry intersecting the Vesle, the salients of Reims and Verdun and the break through at Saint-Mihiel.
In 1919, Rue De La Belle-Vierge, near the Cathedral.
