The rest of the Saillisels had been held and the German hold on St Pierre Vaast wood stopped the French from rolling up the German defences from north to south. The 4th Division took prisoners from Bavarian Infantry Regiment 15 of the 2nd Bavarian Division and the II Battalion, Bavarian Infantry Regiment 15 had 50 percent casualties. Most of Reserve Infantry Regiment 92 was captured and Infantry Regiment 64 of the 6th Division lost of the I Battalion. Infantry Regiment 181 of the 40th Division found that the mud reduced the effect of the British bombardment and the infantry were unable to make a quick advance. Prisoners were taken from I and II battalions, Infantry Regiment 104 at Snag Trench and the III Battalion conducted a counter-attack. On 19 October, the storm detachment of the 40th Division counter-attacked in two columns with flame-throwers, a machine-gun section and the best men of I Battalion, Infantry Regiment 104; the advance of the left column was halted by one of the flame-throwers exploding. Most of the survivors of Infantry Regiment 104 were relieved by III Battalion, Infantry Regiment 134. The trenches of Infantry Regiment 104 were smashed by artillery-fire and the troops were withdrawn, according to the new policy, of avoiding pointless casualties by abandoning outposts of no tactical value.
