Here, on December 8-9, 1915, the Bulgarians delivered a very violent attack, but were driven off with heavy losses. On the 10th the French announced that they were now occupying a new front, along the Bojimia, a branch of the Vardar, and that they were in touch with the left flank of the British.
Meanwhile, on the east side of the Vardar, General Todoroff was continuing his attack on the British. He had massed together about 100,000 men. On the morning of the 6th, after the first assault and under cover of dense mists that were rolling up from the swamps down near Saloniki, he was able to get in close to the British without being seen. As the dawn began breaking he poured a rain of high-explosive shells on the British, which here consisted mostly of Irish regiments.
As on the day before, the enemy came on in successive waves, so thick that the later ones carried the first before them, even when they turned to flee from the heavy fire of the British. Finally the British were again compelled to give way before the heavy impact of numbers. By evening they had retired two miles, not a great deal, considering the masses that were driving them. More than once it looked as though the British would be literally overwhelmed and annihilated. Eight guns were lost and about 1,300 men were killed or wounded.
The retirement had been in the direction of the Vardar and by the end of the second week of December, 1915, the British were able to make another stand over on the banks of the Vardar, below the right wing of the French.
The whole Bulgarian field army was evidently divided between the Rabrovo road and north of Strumitza Junction. It was clearly the enemy's intention to drive a wedge into the center, thus to isolate all the northern divisions and to bring about a general disaster.
Sarrail recognized his danger and began to retire his northern units, covering the movement with a fiercely contested action in the region of Strumitza.

By December 11, 1915, the French and British lines were close back on the Greek frontier, and although the Bulgarians delivered a heavy attack on that day, it was their final effort; the following day the Allies were across the frontier and the Bulgarians made no attempt to follow them. Possibly they were restrained by their German allies, or possibly they had no desire to involve Greece, for had the Bulgarians set foot on Greek soil, it is more than likely that Greek troops would have resisted them, and once such an encounter had taken place, Greece would probably have thrown herself into the war on the side of the Allies. As they retired, the allied troops destroyed the railroad behind them and set fire to Gevgheli and other towns on the other side of the border. And, by a fortunate coincidence, it was on the day before they crossed the frontier that Greece had finally accepted the proposals of the Allies that their forces were to be allowed freedom of movement.
