I’m going to take a break from French colonial cavalry to consider what the BSF was doing at this time, using the Official History of Military Operations in Macedonia (Vol. 2 – 1935) by Capt. Cyril Falls.
We left the British Army and the foreign troops attached to it on the night of the 24th September pressing forward to the Bulgarian frontier, the advanced guard of the XII Corps on the Blaga Planina, the XVI Corps on the southern bank of the Bajima Dere. According to the German account, the demoralization of the defeated Eleventh Army had spread to the troops of the First, whose defence had been brave and successful. It is probable that the the bombing of British aircraft had done a good deal towards bringing this about. Certainly on the 25th September the British and Greeks between Lake Dojran and the Vardar were more troubled by the nature of the country than by resistance of the enemy.
General Milne had no fresh orders to issue, merely directing the corps commanders to continue the advance on the 25th ‘along the same lines and with the same object as today.’
