_The tourist soon arrives at_ =Brécy=, where a German fifteen-inch “Bertha” gun was installed. To visit the ="Bertha” platform= (photo p. 66), _turn to the left at the cross-roads before entering Brécy, pass under the railway-bridge, turn to the left 100 yards further on, and follow the railway towards Châtelet Wood. Rather less than a mile from the cross-roads, the wood comes down to the road; skirt it for about 300 yards, until the railway siding which branches off the main line, and along which the gun was brought to its platform, is reached._ [Illustration: MOUCHETON CASTLE, USED AS G.H.Q. BY THE AMERICANS.] [Illustration: 15-IN. BERTHA PLATFORM IN CHÂTELET WOOD. The road is at the back behind the trees.] Follow this siding into the wood for about 60 yards, where the platform, which the Germans tried to blow up before retreating, will be found. The enemy succeeded in saving the gun. Trees placed in holes along the siding hid the position from the Allied aviators. _Turn the car round in the alley, about 20 yards after the siding, and return to the cross-roads, driving slowly, as the road is narrow and in poor condition._ (_N.B.--Tourists visiting the “Bertha” platform by special excursion from Château-Thierry, can return by the road which follows the railway, instead of retracing their steps, as above. Cross the railway, pass through Bézu-St.-Germain, cross the railway again, turning shortly afterwards to the left along N. 37, which leads direct to Château-Thierry._) [Illustration: FRENCH AND AMERICAN SOLDIERS ON THE “BERTHA” PLATFORM IN JULY, 1918.] [Illustration: THE ORDRIMOUILLE STREAM AT COINCY. In the background: the Church.] _Continue to follow the railway, turn to the right and pass under the railway at the next bridge. Near the bend on the left are_ French graves. _Pass under the bridge, turn to the left into the_ picturesque village of =Coincy=; _cross the river and continue as far as the Church_. [Illustration: THE GERMANS PILLAGED THE CHURCH AT BRÉNY.] [Illustration: GERMAN BARRICADE AT THE ENTRANCE TO OULCHY-LE-CHÂTEAU. In the background: the Hôtel-le-Ville and Church.] _Return to the entrance of the village, take on the right the road which passes under the railway, and follow G. C. 3._ In the wood on the left were numerous ammunition dumps. =Rocourt= is reached shortly afterwards. Take a look at the church, then _turn to the right into N. 37_. All along the road are small dug-outs. The Germans, in their retreat, left behind huge quantities of shells and empty cartridge-cases. Rather less than two miles from Rocourt, in a small wood which borders the road on the left, the Germans had installed batteries of three-inch and four-inch guns. The wood contains ammunition shelters and an underground chamber full of shells. In the sloping land, at the side of the road, small dug-outs can still be seen. A little further on, near a ruined house, are heaps of burnt cable-drums, gun limbers, motors, etc.
