I drew her closer towards me. With an effort she rallied, her arms again tightened in their clasp, and we sped down the long slope which led to Trasimene, Castor stretching himself like a greyhound. I looked again over my shoulder. Far behind my men were riding for their lives, and farther still was the dark line of our pursuers, coming on with dogged persistence, the sun lighting up their armour and flashing from their spears. Once beyond Magione we were comparatively safe, but a false step, a stumble, and all was lost. Magione itself was held by the Baglioni, and from the old watch-tower, built by the Sforza, which stood high above the country, we might have already been spied, and a party sent out to intercept us. The thought seemed to grow into a reality, and a despair began to come over me. "On, on, Castor!" I spoke to the good horse, and he laid his ears back at the sound of my voice, and even as he did so I saw a cloud of dust coming towards our left, and knew that the danger I feared was at hand. Going as we were I was riding right into the party from Magione, and therefore with a touch on the rein, I swung Castor round to the north, and we raced on, leaving the tower over my shoulder. The double burden and the tremendous pace, however, began to tell on the horse, and within the next five minutes he slackened perceptibly in his stride. To my horror I saw that the ground began to be furrowed and cut up by ravines and that we were approaching the bed of a river. I had therefore to slacken the pace, and at the same time our new pursuers sighting us, came on with all the speed of their fresh horses. Castor scrambled in and out of the ravines like a cat, but we were going slowly now, and the enemy had all the advantage of the level ground to come up, which they did at a dreadful rate. With the failing strength of my companion I dared not risk jumps, weighted as I was, but the brave horse did his utmost, as if knowing our danger. "For God's sake hold on!" I cried out as we topped a deep ravine with a plunge that almost caused Angiola to slip from my grasp, and as I said this I heard a shot and a ball from an arquebus whistled over my head. The enemy were in the rough ground now themselves, but they were within gun-range, and I dreaded that some of them might dismount and pick me off. This however did not occur to them, and on we went, with every now and again a bullet, fired from horseback with an unsteady aim singing past us. My charge had twisted her arms into my shoulder belt and held on bravely, but I saw by her white face and the blue coming into her lips that this could not last, and if she fainted there was an end of all.
