On September 23d it became evident that the retreat of the Bulgarians had turned into a rout. Notwithstanding reinforcements of Germans and Bulgars rushed down in a frantic effort to check them, the Allied armies were advancing on an eighty-five mile front, crushing all resistance. The Italian army, on the west, was meeting with equal success, and the news dispatches reported that the first Bulgarian army in the region of Prilep had been cut off. A dispatch received by the British War Office reported "As the result of attacks and continual heavy pressure by British and Greek troops, in conjunction with the French and Serbian advance farther west, the enemy has evacuated his whole line from Doiran to the west of the Vardar." As it retreated the Bulgarian army was burning supplies and destroying ammunition dumps, burning railway stations and ravaging the country.
By this time it was felt throughout the Allied world that the Bulgarian defeat would have important political consequences. It was remembered that a short time before King Ferdinand had paid a visit to Germany, and after long conferences with the German War Lord, had hastily returned to Bulgaria. It was recalled that there had been many signs of serious disorder in Bulgaria, where the Socialist party had been in close touch with the advance parties in the Ukrainian Republic. It seemed possible that the Bulgarian defeats had been brought about by Bulgarian dissension and it was also evident that Germany was in no position to offer effective support to its Bulgarian accomplice.
As the days passed by the news from this front became more and more favorable. At all points the Bulgarian armies were retreating in the most disorderly manner, closely pursued by the Serbians, French, English, Italians, and Greeks. Bulgarian troops were deserting in thousands, and thousands of others were surrendering without resistance.
On September 26th it was announced that the Bulgar front had disappeared; that the armies had been cut into a number of groups and were fleeing before the Allied troops. Town after town was being captured, with enormous quantities of stores. On Friday, September 27th, it was announced that Bulgaria had asked the Allies for an armistice of forty-eight hours, with a view to making peace.
The situation was now causing intense excitement. The Germans tried to minimize the Bulgarian surrender. A dispatch from Berlin declared that Premier Malinoff's offer of an armistice was made without the support of other members of the Cabinet or of King Ferdinand, and that Germany would make a solemn protest against it. German newspapers were demanding that Malinoff be dismissed immediately and court-martialed for high treason. The Berlin message asserted that the Premier's offer had created great dissatisfaction in Bulgaria and that strong military measures had been taken to support the Bulgarian front. According to statements from Sofia it was added a counter-movement against the action of the Premier had already been set on foot. It was declared in Germany that the Premier's act was the result of Germany's refusal to send sufficient reinforcements to Bulgaria. Secretary Lansing made the announcement that the United States Government had received a proposal for an armistice.
It appeared that Bulgaria had been maneuvering toward peace for some time. The Bulgarians had foreseen their inability to meet the expected Allied attack, and had made every effort to obtain German reinforcements. Moreover, they were highly dissatisfied with the treatment they had received from Germany in connection with Bulgaria's dispute with Turkey as to territorial dispositions to be made after the war. Probably the most important reason, however, for the Bulgarian overthrow was that by this time they were sick of the war. They had not, in the first place, gone into it with any enthusiasm, and though they could fight bravely enough against their Serbian foe, no true Bulgarian could ever feel himself in a natural position facing his old-time Russian friend.
Bulgaria had come to the end. Malinoff, the Premier, had from the beginning been opposed to the war. Mobs in Sofia were demanding surrender. Ferdinand was compelled to give way to the wishes of his Cabinet and his people, and in spite of the fact that he had promised the Kaiser to remain faithful to the Alliance, he gave his consent to the movement for unconditional surrender.
An official Bulgarian statement read as follows: "In view of the conjunction of circumstances which have recently arisen, and after the position had been jointly discussed with all competent authorities, the Bulgarian Government, desiring to put an end to the bloodshed, has authorized the Commander-in-Chief of the army to propose to the Generalissimo of the armies of the Entente at Saloniki, a cessation of hostilities, and the entering into of negotiations for obtaining an armistice and peace. The members of the Bulgarian delegation left yesterday evening in order to get into touch with the Plenipotentiaries of the Entente belligerents." This statement was dated September 24th.
When the Bulgarian officers entrusted with the proposal for an armistice presented themselves at Saloniki, General d'Esperey gave the following reply: "My response cannot be, by reason of the military situation, other than the following. I can accord neither an armistice nor a suspension of hostilities tending to interrupt the operations in course. On the other hand, I will receive with all due courtesy the delegates duly qualified of the Royal Bulgarian Government." The Bulgarian delegates were General Lonkhoff, commander of the Bulgarian Second Army, M. Liapcheff, Finance Minister, and M. Radeff, a former member of the Bulgarian Cabinet.
On the evening of the 29th an armistice was signed. The terms of the surrender were approved by the Entente governments, and hostilities ceased at noon September 30th. The terms of the armistice were as follows:
