Bellarion took a stick of charcoal and on the pine board drew lines to elucidate his plan. 'Here the track runs. From this the party cannot stray by more than a quarter-mile on either side; for here the river, and there another watercourse, thickly fringed with young poplars, will prevent it. I would post the men in an unbroken double line, along an arc drawn across this quarter-mile from watercourse to watercourse. At some point of that arc the party must strike it, as fish strike a net. When that happens, the two ends of the arc will swing inwards until they meet, thus completely enclosing their prey against the chance of any single man escaping to give the alarm.'
Facino nodded, smiling through his gloom. 'Does any one suggest a better way?'
After a pause it was Carmagnola who spoke. 'That plan should answer as well as any other.' Though he yielded, vanity would not permit him to do so graciously. 'If you approve it, my lord, I will see the necessary measures taken.'
But Facino pursed his lips in doubt. 'I think,' he said after a moment's pause, 'that Bellarion might be given charge of the affair. He has it all so clear.'
Thus it fell out that before evening Bellarion was back again in Stoffel's quarters. To Casalbagliano also were moved after night had fallen two hundred Germans from Koenigshofen's command at Aulara. Not until then did Bellarion cast that wide human arc of his athwart the track exactly midway between Casalbagliano and Alessandria, from the Tanaro on the one side to the lesser watercourse on the other. Himself he took up his station in the arc's middle, on the track itself. Stoffel was given charge of the right wing, and another Swiss named Wenzel placed in command of the left.
The darkness deepened as the night advanced. Again a thunderstorm was descending from the hills of Montferrat, and the clouds blotted out the stars until the hot gloom wrapped them about like black velvet. Even so, however, Bellarion's order was that the men should lie prone, lest their silhouettes should be seen against the sky.
Thus in utter silence they waited through the breathless hours that were laden by a storm which would not break. Midnight came and went and Bellarion's hopes were beginning to sink, when at last a rhythmical sound grew faintly audible; the soft beat of padded hooves upon the yielding turf. Scarcely had they made out the sound than the mule train, advancing in almost ghostly fashion, was upon them.
The leader of the victualling party, who knowing himself well within the ordinary lines had for some time now been accounting himself secure, was startled to find his way suddenly barred by a human wall which appeared to rise out of the ground. He seized the bridle of his mule in a firmer grip and swung the beast about even as he yelled an order. There was a sudden stampede, cries and imprecations in the dark, and the train was racing back through the night, presently to find its progress barred by a line of pikes. This way and that the victuallers flung in their desperate endeavours to escape. But relentlessly and in utter silence the net closed about them. Narrower and narrower and ever denser grew the circle that enclosed them, until they were hemmed about in no more space than would comfortably contain them.
Then at last lights gleamed. A dozen lanterns were uncovered that Bellarion might take stock of his capture. The train consisted of a score of mules with bulging panniers, and half a dozen men captained by a tall, loose-limbed fellow with a bearded, pock-marked face. Sullenly they stood in the lantern-light, realising the futility of struggling and already in fancy feeling the rope about their gullets.
Bellarion asked no questions. To Stoffel, who had approached him as the ring closed, he issued his orders briefly. They were surprising, but Stoffel never placed obedience in doubt. A hundred men under Wenzel to remain in charge of the mules at the spot where they had been captured until Bellarion should make known his further wishes; twenty men to escort the muleteers, disarmed and pinioned, back to Casalbagliano; the others to be dismissed to their usual quarters.
