No I am not your backtracking and trying to hide the glaring error you made.
Gough who commanded the 5th was made the scapegoat for the retreat by Lloyd George who over ruled Haig and had Gough sacked. Taken from wiki the historian Andrew Roberts writes
the offensive saw a great wrong perpetrated on a distinguished (sic) British commander that was not righted for many years. Gough's Fifth Army had been spread thin on a forty-two-mile front lately taken over from the exhausted and demoralised French. The reason why the Germans did not break through to Paris, as by all the laws of strategy they ought to have done, was the heroism of the Fifth Army and its utter refusal to break. They fought a thirty-eight-mile rearguard action, contesting every village, field and, on occasion, yard . . . With no reserves and no strongly defended line to its rear, and with eighty German divisions against fifteen British, the Fifth Army fought the Somme offensive to a standstill on the Ancre, not retreating beyond Villers-Bretonneux...
If you cant even distinguish between 2 different actions fought by two different Armies 3 weeks apart then instead of shouting at everyone to read your favourite book and get the facts right right perhaps you should do some fact checking.
