During early 1918, the Germans launched a major offensive on the Western Front after the collapse of Russia allowed them to increase their forces in the west. Falling initially against the British southern flank, the offensive pushed the Allies back significantly, and the squadron was forced to withdraw to airfields further back from the front as German forces advanced steadily: in March it moved to La Bellevue and then to Fouquerolles, remaining there until June when it moved to Liettres to support the French during the Marne offensive. During this time, the squadron was attached to the Royal Air Force's Nos 10, 22, 51 and (finally) 80 wings. Despite the moves, the squadron maintained a high operational tempo, becoming involved in heavy air-to-air combat during fighter sweeps, and also being used to attack advancing German ground forces (see image left). After the German offensive was finally halted, the Allies launched their own offensive in August around Amiens after which the squadron was employed to attack German airfields, and as the Germans were forced back, attacking withdrawing German troops on the ground. Throughout October, in an effort to keep up with the advance, the squadron moved three times and by the time the armistice was signed in November it was based at Pont-a-Marq.
