On April 6, 1918, after heavy losses, the 1st Division was removed to the rearguard, leaving the 2nd Division (reinforced with the 6th Brigade from the 1st Division) as the sole CEP division on the front line. The 2nd division assumed the responsibility of all the Portuguese sectors, rearranged as the Fauquissart, the Neuve Chapelle and the Ferme du Bois sectors (11 km of front), now under the operational control of the British XI Corps.

The 2nd Division was also planned to be moved to the rearguard on April 9, 1918, on the same day German Army launched operation Georgette, the great offensive whose main thrust was precisely on the sectors defended by the Portuguese Division. In the resulting Battle of the Lys, the 20,000 Portuguese of 2nd Division suffered an assault from 100,000 Germans, supported by a heavy artillery bombardment. Despite stubborn resistance, the Portuguese Division was overrun and lost c. 7,000 casualties. From December 22, 1917, to April 6, 1918, the 2nd Division was responsible for the sectors of Fauquissart and Chapigny of the Portuguese Sector of the Western Front.
