Lesbœufs and Flers and beyond Gueudecourt on the right, knocked out, as we know, both battalions of the Irish Guards for the time being.
On the 27th and 28th of September the Second and First Canadian Divisions, with the Eleventh and Eighteenth of the Second Army Corps, captured Thiepval, the Stuff and Schwaben redoubts on the left of the line; while the Fifty-fifth and New Zealand Divisions made possible an advance on Le Sars and Eaucourt l'Abbaye villages in the centre, which, after four days' continuous fighting by the Forty-seventh, Fiftieth, and Twenty-third Divisions, ended in the taking of Eaucourt l'Abbaye and Le Sars.
On the 7th of October the French Army attacked in the direction of Sailly-Saillisel, the Fourth Army chiming in along its whole front from Lesbœufs to Destremont farm, which had been taken by the Twenty-third Division on the 29th September. In this affair the Twenty-third Division captured Le Sars, and the Twentieth Division over a mile of trenches east of Gueudecourt.
Then the treacherous weather broke once more, and the battered and crumbled ground held their feet till a few days of dry cold were snatched for an attack in the direction of Courcelette by four Divisions (Fourth Canadian, Eighteenth, Fifteenth, and Thirty-ninth), where a fresh line was needed.
On the 23rd October, and on the 5th November again, as side-issues while waiting on the weather for a serious attack on Beaumont-Hamel, a couple of divisions (Fourth and Eighth) went in with a French attack against Pierre St. Vaast Wood, where a tangle of enemy trenches at the junction of the two armies was slowly smoked and burned out.
The 10th of November (after one day's fine weather) gave the Fourth Canadian Division a full day's fighting and, once more, a thousand yards of trench in the Courcelette sector.
On the 13th of November the battle of the Ancre opened from Serre to east of the Schwaben redoubt
