That same day Major Baggallay, M.C., carried out a road reconnaissance of the front at Doignies and Demicourt north of Havrincourt Wood. The situation there betrayed nothing. "Apparently the whole of that front-sector was habitually very quiet."
Twenty-four hours later, it was alive and roaring with our tanks rooting through the massed wire of the Hindenburg Line, the clamour of half-a-dozen divisions launched at their heels and the smashing fire of our guns in advance of them and their covering smoke-screens; while far to the north and south dummy attacks, gas and artillery demonstrations veiled and confused either flank. The opening day was, beyond doubt, a success. The German line went out under the tanks, as breakwaters go out under the race of a tide; and from Gonnelieu to north of Hermies three systems of their defence were overrun to a depth of four or five miles. By the 21st November our attack had punched out a square-headed salient, ten miles across the base, the southerly side of which ran along the high ground of the Bonavis Ridge, more or less parallel to the St. Quentin-Escaut Canal from Gonnelieu to Masnières, which latter place we held. The easterly side lay from Masnières through Noyelles-sur-l'Escaut and Cantaing to Fontaine-Notre-Dame and Bourlon Wood. This latter, as the highest point of command, was the key of the position on our north flank. Thence, the northerly flank of the salient ran roughly westward from the wood, south of Mœuvres till it joined our original front north of Boursies. About one half of the salient was commanded by German guns from the north of Bourlon Wood, and the other half from the south in the direction of the Bonavis Ridge.
Besides these natural disadvantages there were large numbers of our cavalry hopefully disposed on the main routes in readiness for the traditional "break-*through," the harrying of enemy communications, etc. November on the Somme is not, however, quite the best season for exploits of horse, sabre and lance.
