North-east of Mont Haut, the advance reached a depth of 2. The French spent 18 April consolidating and the 45th Division pushed up to the southern edge of Mont Haut. The "Monts" were held against a German counter-attack on 19 April, between Nauroy and Moronvilliers, by the 5th Division and 6th Division , which had been trained as Eingreifdivisionen specialist counter-attack divisions , supported by the 23rd Division plus one regiment. On 20 April, French troops got onto the summit of Le Casque and on 22 April, the eastern and lower summit of Mont Haut was secured by the 45th Division.
The Fourth Army took 3, prisoners and 27 guns. Counter-attacks by the German 4th Army on 27 May had temporary success, before the French recaptured ground around Mont Haut; lack of troops had forced the Germans into piecemeal attacks, instead of a simultaneous attack all along the front.
The French attacked again from 17 to 22 April and despite German counter-attacks on 19 and 23 April, advanced slightly on the Heights of Moronvilliers. After a lull, the French attacked again on 30 April and ended the offensive on 20 May.
The number of German prisoners taken by the end of the battle had been increased to 6,, with 52 guns, 42 mortars and machine-guns. The Moronvilliers massif was a group of hills, densely wooded before , to the west of the Suippes river. The village of Moronvilliers lay in a dip below the north crest of the main ridge. West of the ridge, which in was between the left flank of the French Fourth Army and the Fifth Army, was an area of low ground about 11 km 7 mi wide, between the Moronvilliers massif and the Nogent l'Abbesse massif east of Reims, in which lay the village of Beine.
The highest point of Mont Haut is nearly as high as Vigie de Berru m ft , the highest hill overlooking Reims from the east. The capture of Mont Sans Nom and the Moronvilliers Ridge would threaten the German hold on the Beine basin and the Nogent l'Abbesse massif; the loss of these would make the German positions on the Fresne and Brimont heights untenable. Success would allow the Fourth Army to advance towards the Suippes, between St Martin l'Heureux and Warmeriville to the north-west, outflank the Nogent l'Abbesse hills from the north.
