Further casualties during September included Lieut., C. Potter and 2/Lieuts. O. H. Mattison and J. McDonald, to hospital.
2/Lieut. Cook was appointed to the 173rd L.T.M. Battery.
On the 30th September the 58th Division was withdrawn from the line and concentrated as Corps reserve for rest in the Nordausques area (eight miles north-west of St Omer), and the 2/4th Londons moved by rail from Vlamertinghe to Zouafques where they went into billets on the 1st October. The train was followed and bombed during the journey by German airmen, 1 sergeant and 2 men being killed.
During the period of the 58th Division's withdrawal from the line the offensive was pressed forward under adverse conditions of weather. The season was now becoming advanced and the condition of the ground offered a far greater obstacle to our progress than the enemy's resistance. Probably no series of battles of the whole war was waged under such persistently adverse conditions, or imposed a greater physical strain on the attacking troops. In every direction the salient was by now a series of "shell hole lakes" the ground being waterlogged and the mud more glutinous than ever. An increasing number of casualties to men and beasts occurred through drowning in the shell holes of this ghastly shell-battered inferno, but though the whole forces of the elements seemed to be arrayed against us, advances of enormous importance were achieved during the early part of October, as a result of which the Allied positions were pushed forward to the outskirts of Houthulst Forest, to the east of Poelcapelle and to within 2000 yards of Passchendaele.
The prolonged continuance of active operations was obviously becoming increasingly difficult, but G.H.Q. was impelled to pursue the course of this dreary offensive partly by reason of the serious situation caused on the Italian front by the defeat of Caporetto at the end of October, and partly by the need of containing as many German divisions as possible during the preparations for the Cambrai battle, which were not yet complete.
The 2/4th Londons remained at Zouafques training and reorganising for over three weeks. Several drafts were received from the Base, which together made the considerable addition of 244 N.C.O.'s and men to the Battalion strength, thus bringing it above its numbers prior to the action of the 20th September.
On the 15th October the Battalion was joined by 2/Lieut. H. G. Langton; and by 2/Lieuts. H. A. Snell, J. R. Naylor and R. J. Richards (1st Londons). During this period also 2/Lieuts. H. E. English and C. C. H. Clifford were evacuated sick. Capt. S. H. Stedman was posted to the 173rd Brigade Labour Company at Louches.
On the 23rd October the 2/4th Londons returned by train to the Vlamertinghe area and took over quarters in Siege Camp, moving the following day to the concentration area on the canal bank, whence the battle surplus under 2/Lieut. Askham left the Battalion for the Divisional Depôt Battalion.
