(_See outline map, p. 39._) The following itinerary includes practically all the places in the battle area where the troops of the 1st and 3rd American Army Corps distinguished themselves. In May, 1919, deeply moving traces of the fierce fighting were visible all along the road, and will probably long continue to exist. The ruined villages are as the shells and bombs left them. Everywhere are branchless trees and stumps, shell craters roughly filled in, trenches, barbed wire entanglements, and shelters for men and ammunition. Thousands of shells, shell casings, rifles, gun-limbers, and machine-guns lie scattered about. Corpses are occasionally seen. Before the War this part of the country was one of the prettiest and most interesting in France. In nearly every village there was either an old church, a castle, or ruins of archæological interest. 1st day.--PARIS--CHÂTEAU-THIERRY. _Leave Paris by the Avenue Jean Jaurès, Pantin Gate, and the National Road N. 3._ (_At the Toll-Gate ask for a “bon de réintroduction” (free) for the gasoline in the tank and reserve tins. This will enable the tourist, on his return, to enter Paris with a similar quantity of gasoline free of charge._) N. 3 goes straight ahead and is easy to follow, the “milestones” being plainly marked “N. 3.” The localities of Pantin, Bondy, Livry, Villeparisis, and Claye are successively passed through, =Meaux= being afterwards reached by the Route de Paris and the Rue du Faubourg St. Remi. (See the =Michelin Illustrated Guide=, “=The Battle of the Marne, 1914=,” _for directions for visiting this beautiful, historical city, and for a detailed description of the fighting in this sector_.) _Turn to the right, pass under the railway bridge, continue straight along the Rue St. Remi, skirt the Cathedral, then follow the Rue St. Nicolas and the Rue du Faubourg St. Nicolas._ The following villages are next passed through without difficulty: Trilport, St. Jean-les-deux-Jumeaux and Sammeron, after which the tourist arrives at La Ferté-sous-Jouarre. _Turn to the left into the Rue de Condé, and again to the left into the Rue du Faubourg, cross the Marne, and continue straight ahead along the Rue du Pelletier and Rue du Limon. Crossing over the railway the road turns to the right, rising above the valley of the Marne._ Montreuil is next passed through. Just before entering =Le Thiolet= (the first ruined village on the tour), along the left side of the road, there is an American Cemetery. Shortly after, =Vaux= is reached, but before coming to it, another American Cemetery will be seen to the left of the road. This village, which is situated in a hollow, was literally wiped out (photo, p. 60). The ruins in the bottom of the valley, to the right of the road, are most impressive. (_The tourist will visit them on his way to Essommes, as per the Itinerary._) The road skirts =Hill 204=, which dominates the surrounding country on the right, and which was hotly disputed (p. 62).
