In 1916, the division was reformed in France as the 55th (West Lancashire) Division and was reassigned its original units. During the Battle of the Somme, the division fought several actions at Guillemont, Ginchy, and Morval. In 1917, the division fought at Pilckem and the Menin Road Ridge, during the Battle of Passchendaele, and gained an excellent reputation. Late in 1917, the division fought in the Battle of Cambrai. Towards the end of the battle, a major German counterattack forced the division back over . A court of inquiry was convened to examine this loss of territory and the division's conduct. The inquiry delivered findings that proved controversial with contemporary soldiers and modern historians. In 1918, the division faced the German spring offensive, and conducted a much-lauded defence of Givenchy during the Battle of Estaires. After the German offensive stalled, the division joined in the Hundred Days Offensive, the culminating offensive of the war. The division suffered almost 36,000 casualties, with 6,520 killed, in over two years of combat. After the end of hostilities, the division was slowly demobilised and eventually disbanded in 1919. In 1920, the division was reformed in England.
