North-west of Rheims was the 5th Army (Gen. Mazel), of which the 38th Corps (Gen. de Mondesir) held the immediate approaches to the town, followed by the 7th Corps (Gen. de Bazelaire), 32nd Corps (Gen. Passaga) astride the Aisne, and, extending beyond Craonne, the 5th Corps (Gen. de Boissoudy) and the 1st Corps (Gen. Muteau). East of Rheims the 4th Army (Gen. Anthoine) was engaged only during the second stage of the battle. At 6 a.m. on the 16th, in drenching rain, the 5th Army attacked all along the front, in conjunction on the left with the 6th Army (Gen. Mangin), which undertook to storm the Chemin-des-Dames. The enemy was expecting the attack, and had concentrated very large forces and powerful artillery. Despite their bravery, the French were unable to break through. [Illustration: EXPLANATORY MAP OF THE MILITARY OPERATIONS IN 1917] In the Rheims sector, the 32nd Corps advanced three kilometers to the north of the Aisne. The 7th Corps crossed the canal at Loivre and captured Berméricourt in the morning, but was forced to give up part of the conquered ground in the afternoon, in consequence of a powerful German counter-attack. In front of Brimont a brigade of the 38th Corps failed to pierce the enemy's positions. On the 17th, while the army of General Mazel resisted a violent enemy counter-attack, General Anthoine attacked from the east of Rheims to Auberive with the 8th Corps (Gen. Hély d'Oissel), 17th Corps (Gen. J. B. Dumas), 12th Corps (Gen. Nourrisson). At 4.45 a.m., despite violent squalls of rain and snow, the French infantry rushed forward and carried the first German lines along a front of eleven kilometers. The 34th Division (Gen. de Lobit) carried the Mont Cornillet and Mont Blond hills, which the enemy attempted in vain to recapture. On April 18 and 19, and May 4 and 5, the fighting was spasmodic and finally ceased. On the whole, the French offensive failed, and Rheims continued to remain under enemy gun-fire. On the morning of May 27, 1918, the Germans commenced a powerful offensive between Vauxaillon (on the Chemin-des-Dames) and the Fort of Brimont. At the beginning of the attack, the French line passed through Bétheny and along the Aisne-Marne Canal. In the evening, after the loss of the Chemin-des-Dames and the Aisne Canal, Rheims was no longer protected on the north-west, except by the St. Thierry Heights, which were soon turned. The Germans crossed the Vesle at several points, principally at Bazoches and Fismes, and advanced as far as Muizon. On May 29, the French line passed through La Neuvillette, Châlons-sur-Vesle, Muizon and Rosnay. On the 30th, it extended from Perquin Farm to Méry-Premecy, via Champigny. On the 31st, Tinqueux and Vrigny fell. Further to the south the Germans advanced along the valley of the Ardre towards the Château-Thierry--Epernay--Châlons railway, threatening Epernay (_see the Michelin Guide: "The Second Battle of the Marne"_).
