For a month the garrison reported to be starving was drawing in supplies from a big section of farming country. When the armistice was signed it still had pasturage within the lines of defense for flocks of sheep and herds of cattle. The problem for the Bulgars first and last was to keep this fact masked and to check the savage sorties and spare all the guns and men they could for the main army. Volunteers from Macedonia still in native dress, clerks still in white collars, old men who had perjured themselves about their age in order to get a rifle, and the young conscripts of twenty years came to take the place of the regular forces on the investing lines, who moved on to re-enforce Demetrief. Fifty thousand Servians, two divisions, were spared after Kumanova, and speeded across Bulgaria on the single-line railway with an amazing rapidity to assist, according to plan, the Bulgars in the investment operations. To the Turk, Adrianople is a holy city. Here is the most splendid mosque in all the empire, that built by the conqueror Sultan Selim. With the shadow of the minarets over his shoulder, the Turkish private in a trench was ready to die for Allah. But death must come for him. He is not going to hustle intelligently after paradise. In short, he is a sit-and-take-it fighter. While any delay of the Bulgarian advance was invaluable in gaining time, he made no use of his opportunities in a country of hills and transverse valleys and ravines, which nature meant for rear-guard action. A company of infantry posted on a hill could force a regiment to deploy and attack, and a few miles farther on could repeat the process. Cavalry could harass the flanks of the attacking force. Field-guns could get a commanding position above a road, with safe cover for retreat. At Mustapha Pasha, twenty miles in front of Adrianople, was a solid old stone bridge over the Maritza, whose floods in the winter rains would be a nightmare to engineers who had to maintain a crossing with pontoons. If ever a corps needed a bridge the second Bulgarian corps needed this one. They found that a small and badly placed charge of dynamite had merely knocked out a few stones between two of the buttresses, leaving the bridge intact enough for all the armies of Europe to pass over it; and the Turks did not even put a mitrailleuse behind sandbags in the streets or use field-guns from the adjacent hills to delay the Bulgars in their crossing.
