Evidently the invaders, who would formerly have been more than content with the withdrawal of the Greek forces, were now--in violation of the pledges given to Athens by the German and Bulgarian Governments--resolved on making such withdrawal impossible. It is not hard to account for this change. The pledges were given in the belief that Greece would continue neutral. This belief had been shaken not only by the Venizelist movement, but more severely still by M. Zaimis's soundings of the Entente Powders. The Greek Premier had from the first insisted on secrecy, stating among the main reasons which rendered absolute discretion imperative, "the presence in part of our territory of the eventual adversary," and "the need to extricate two divisions and a large quantity of material" from their grip.[9] Nevertheless, the Entente Press gloried in the hope that the Allies would soon have the only non-belligerent Balkan State fighting on their side, and the principal Entente news agency trumpeted abroad M. Zaimis's confidential conversations.[10] Hence the desire of the Germano-Bulgars to prevent the escape of men and material that might at any moment be used against them. On the other hand, the Greek officers' council decided {120} to try first every means of escape, and only if that proved impossible to comply with the German demand on condition that they should be taken to Germany and not be left in the hands of the Bulgars. Accordingly, Colonel Hatzopoulos addressed a most earnest appeal to the British for vessels to get his men away to Volo or the Piraeus, and, having received a promise to that effect, he secretly arranged for flight. In the night of 10 September all the men with their belongings gathered on the sea-front ready to leave. But they reckoned without the partisans of M. Venizelos in their midst. One of them, the Commandant of the Serres Division, a month ago had informed General Sarrail that he would fight on the side of the Allies,[11] and another on 5 September, in a nocturnal meeting on board a British man-of-war, had proposed to kidnap Colonel Hatzopoulos, arm volunteers, and attack the Bulgars with the aid of Allied detachments landed at Cavalla. His proposal having been rejected, it was agreed that all "patriotic" elements should be transported to Salonica. In pursuance of this agreement, only those were allowed to embark who were willing to rebel. Those who refused to break their oath of allegiance to their King were turned adrift. Some tried to gain the island of Thasos, but their boats were carried to the open sea and capsized, drowning many, the rest got back to the shore in despair.
