In 2018, Michel Goya wrote that the tanks had been more effective than in April and May but were still mechanically unreliable, with a 25 per cent breakdown rate and that the modifications did not alter the mechanical wear on the vehicles.
Medium tanks were vulnerable and lacked the manoeuvrability to cross severely cratered ground.
The crews found it hard to reach objectives and became much more vulnerable when stationary.

The offensive had been intended to capture high ground from the Mont des Singes to the Californie Plateau above Craonne and be economical in infantry, rather than break through the German fortified zone.
Pétain issued a communiqué on the evening of 23 October, announcing that the Sixth Army had taken more than 7,500 prisoners and an enormous quantity of equipment, including 25 heavy and field guns.

While the German 7th Army occupied the Mont des Singes, Laffaux, Allemant and Malmaison plateaux, the French positions north of the Aisne were vulnerable to attack and the alternative for the French was to fall back behind the Aisne.
On 24 October, a German communiqué announced that Allemant, Vaudesson and Chavignon had been lost but claimed victory west of La Royère Farm, where no attack had taken place.
On 25 October, Pinon and the forest had been captured and the French closed up to the line of the Canal de l'Oise à l'Aisne.
In four days, the French had advanced 9.7 km (6 mi) and forced the Germans from the plateau of the Chemin des Dames to the north bank of the Ailette valley.
The attacks at Verdun in August and at Malmaison were compared with the failures of the Nivelle Offensive and were used to produce L’instruction sur l’action offensive des grands unités dans la bataille (Instruction on Offensive Action of Large Units in Battle [31 October 1917]).

The French success at La Malmaison prevented Hindenburg and Ludendorff from further reinforcing the Austro-Hungarians in Italy and assisted the surprise gained by the British at the Battle of Cambrai (20 November – 7 December).
The ground taken by the Sixth Army increased the difficulties of the Germans in the spring offensives of 1918.
Had the 7th Army retained the western end of the Chemin-des-Dames ridge, the German offensive in 1918 could have started simultaneously with the offensives from the Somme to Flanders.
The extension of the northern face of the salient from Vauxaillon to Craonne and Berry-au-Bac, beyond the Chemin-des-Dames ridge to the left bank of the Ailette during the Battle of Malmaison, caused Ludendorff to hold back Heeresgruppe Deutscher Kronprinz (Army Group German Crown Prince), until Allied reserves had been shifted west and north of Soissons.
Had the 7th Army retained the western end of the ridge, the French at the east end and between the ridge and the Aisne, would have been highly vulnerable to a simultaneous attack.

The official historians of the Reichsarchiv wrote that the German defence had been outnumbered threefold in artillery, which had prepared the attack with almost unlimited ammunition.
The closure by gas bombardment of the Ailette valley a few days before the French attack, had made withdrawal impossible (as had a similar bombardment at Verdun in August), which accounted for the French claim of 11,500 prisoners, along with 200 guns, 222 trench mortars and 700 machine-guns.
The Reichsarchiv historians recorded 18,000 casualties, of whom 10,000 were missing.
The magnitude of the defeat, after the severity of the losses at Messines Ridge, Verdun and Ypres, showed that carefully prepared attacks against German defences in tactically unfavourable positions could inflict costly defeats.
Such defeats could have been mitigated by German tactical withdrawals, as soon as Allied artillery preparation began.
The Laffaux Salient had been retained despite the risks, because of the confidence of the local commanders in the fortifications and as a jumping-off point for an offensive in 1918.
