It seemed to my unaccustomed eyes impossible that, without treachery on the part of the mountain tribes, the Turks could dare to break their way through. Even with treachery as an ally, to pass the hills would be dangerous. The enemy would never be sure that the fickle population might not turn again; and to have such a labyrinth of defiles in the rear, across the communications, would be worse than having it in front. Without the friendship of the tribes, the Turks would own only the ground on which their soldiers stood; and lines so long and complex would soak up thousands of men in a fortnight, and leave none in the battlefront.
