The forward British positions across the battlefield are by now thinly held. The units that had attacked on the 25th are exhausted, and the reserves scattered. The vital positions at Fosse 8, the Quarries and Hill 70 have all been lost. German strength was increasing as the failure of French Tenth Army failed to occupy their reserves. It was time to regroup, and rethink. The Big Push had broken into the enemy positions, but not through them. Discussions between the British GHQ and French Tenth Army HQ on the morning of 28th September concluded that the French should relieve the 47th Division to enable the British First Army to create a reserve; that First Army would secure Hill 70, following which the French would extend their left to this position; the BEF would then push on to Pont a Vendin, some 3 miles East of Hulluch.

Sir John French informed Sir Douglas Haig that he would supply the 12th and 46th Divisions to replace the shattered 21st and 24th. Both Divisions are ordered to move to the Loos area from Ypres. There was again mist, low cloud and rain all day.

Units of French Tenth Army reach Hill 140, the crest of Vimy Ridge. German reserves are moved from the area facing the British to stem this attack.

9.30am, 85th Brigade of 28th Division, supported by 83rd Brigade, attacked at the Dump and Fosse 8. Many casualties were suffered by both sides in desperate fighting in the confined trenches around the Hohenzollern Redoubt.

At around 4.00pm, 2nd Guards Brigade attacks Puits 14 bis, but after suffering very heavy casualties from machine-guns firing from in front of Bois Hugo they are ordered to halt.

Desperate fighting continues in the Hohenzollern Redoubt.

Units of 22nd Brigade of 7th Division are finally relieved in front of the Quarries. A night attack by the enemy causes a loss of parts of Gun Trench from this Division.

Formations in the Loos area consolidate their positions; 21st and 24th Divisions prepare to withdraw. 142nd Brigade of 47th Division relieves 3rd Guards Brigade in Loos and on Hill 70. Germans shell the village with 8-inch gun.

The offensive in Champagne is halted. Detailed instructions are issued for the renewal of the Loos offensive towards the Haute Deule Canal, which would now take place on 4th October. A new jumping-off trench is dug through solid chalk during the night, parallel with the Lens road, near the Chalk Pit. French units finally begin to relieve British ones - two days late due to bad weather and the mass of traffic on roads to the rear.

Close fighting is renewed in the Hohenzollern Redoubt, and all but Big Willie Trench is lost to the enemy.

12th Division relieves 1st and 2nd Guards Brigades in area of the Chalk Pit. They are put to work on completing preparations of new trenches, roads and positions in preparation for the assault. Heavy enemy shelling causes many casualties among the working parties. Major-General Wing, OC 12th Division, is among those killed. The renewal of the offensive is delayed until 6th October, to enable preparatory attacks on Fosse 8 and Hill 70 to take place. Following the days loss of the trenches of Hohenzollern Redoubt, this area takes priority. The 12th and Guards Divisions are ordered to capture the Quarries and the Fosse 8 / Hohenzollern respectively, on 9th October.
