Thus the enemy armies were cut in two. The rapid advance of the French and Serbs had driven a deep wedge in between the XI German Army and the rest of the hostile forces. The XI Army was partly on the mountains to the north of the Monastir-Prilep plain, and partly in the Kalkandelen area; the 2nd, 4th, 5th, 9th, and 13th Divisions of the I Bulgarian Army were echeloned between the Uskub-Kumanovo road and the valley of the Strumitza, but they had lost a large part of their artillery; the II Army was still on the lower Struma, and its retreat towards Bulgaria was seriously threatened by the Anglo-Greek advance. Bulgaria was invaded by the British in the Strumitza Valley, the Serbians were watching on the Bulgarian-Macedonian frontier between Tzarevo Selo and Pehtzevo, ready to descend on the territory of the hated enemy and take vengeance for their past sufferings. The I Greek Corps, which until then had remained inactive, was now ready to cross the valley of the Struma and launch an attack on Serres and Demir Hissar. General Mombelli was making his preparations for a general attack on Sop, where large Bulgarian forces were concentrated. The attack was to take place on the morning of the 30th in order to compel the enemy to surrender. The German Commands of the XI Army, of the LXI and LXII Corps, and of the 302nd Division, as well as the artillery, machine-gun companies and German specialist detachments, realizing that the Bulgarian defeat was now inevitable, fled in the night, after having cut all the telegraph and telephone wires, so that for several days the Bulgarian Army had no communication with the rest of the army or with their country. It had to improvise new Commands and Staffs for its units, which had been abandoned by their erstwhile omnipotent Allies. The attack on Sop was to have been launched from the north and north-east by the Sicilia Brigade, and contemporaneously from the south and south-west by the Ivrea and Cagliari Brigades, but at 5.30 General Mombelli received a wireless message announcing the conclusion of the Armistice, which was to come into force on that very day. The attack was therefore suspended, and the Bulgarian Commander invited to surrender. But as the communications with their G.H.Q. and with the Sofia Government had been cut, he refused at first to believe the news, and it took two days of discussion, conducted on the Italian side by General Freri, Commander of the Cagliari Brigade, to convince the Bulgarians, and it was only on October 3rd that the surrender took place. The capitulation was unconditional, the officers alone being allowed to retain their swords and revolvers. The prisoners comprised a Divisional Commander, two Brigadiers, 16 field officers, 224 junior officers, and 7,727 men; 8 guns and 70 machine guns, and a large quantity of other booty were captured. At the same time, the rest of the troops who had been fighting against us on the Stramol and Baba
