The attack was fully two thirds of the way across the ford, which may have been some two hundred yards in width, before Bellarion's men were in their new positions. He ordered a volley of twenty bolts, so as to judge the range; and although only half of these took effect, yet the demoralisation created, in men who had been conceiving themselves invulnerably sheltered, was enough to arrest them. A second volley followed along the low line of exposed flank, and, being more effective than the first, flung the column into complete disorder.
Dead men lay awash where they had fallen; wounded men were plunging in the water, shouting to their comrades for help, what time their comrades cursed and raved, rousing the echoes of that normally peaceful valley, as they had been roused before when the horsemen found themselves in similar plight. Odd shutters and doors went floating down the stream, and the continuity of the improvised roof having been broken, those immediately behind the fallen found themselves exposed now in front as well as on the flank.
A mounted officer spurred through the water, shouting a command repeatedly as he came, and menacing the disordered ranks with his sword. At last his order was understood, and the timber shields were swung from overhead to cover the flank that was being assailed. That, thought Buonterzo, should checkmate the defenders of the ford, who with such foresight had shifted their position. But scarcely was the manœuvre executed when into them came a volley from the thirty men Bellarion had left at the head of the bluff in anticipation of just such a counter-movement. Because the range here was short, not a bolt of that volley failed to take effect, and by the impression it created of the ubiquity of this invisible opponent it completed the discomfiture of the assailants. They turned, flung away their shields, and went scrambling back out of range as fast as they could breast the water. To speed them came another volley at their flanks, which claimed some victims, whilst several men in their panic got into deep water and two or three were drowned.
Livid with rage and chagrin, Buonterzo watched this second repulse. He knew from his earlier observations and from the extent of the volleys that it was the work of a negligible contingent posted to cover Facino's retreat, and his wrath was deepened by the reflection that, as a result of this delay, Facino might, if not actually escape, at least compel him now to an arduous pursuit. No farther than that could Buonterzo see, in the blindness of his rage, precisely as Bellarion had calculated. And because he could see no farther, he stood obstinately firm in his resolve to put a strong force across the river.
The sun was mounting now towards noon, and already over four hours had been spent at that infernal ford. Yet realising, despite his impatience, that speed is seldom gained by hastiness, Buonterzo now deliberately considered the measures to be taken, and he sent men for a mile or more up and down streams to seek another passage. Another hour was lost in this exploration, which proved fruitless in the end. But meanwhile Buonterzo held in readiness a force of five hundred men-at-arms in full armour, commanded by an intrepid young knight named Varallo.
'You will cross in spite of any losses,' Buonterzo instructed him. 'I compute them to number less than two hundred men, and if you are resolute you will win over without difficulty. Their bolts will not take effect save at short range, and by then you will be upon them. You are to give no quarter and make no prisoners. Put every man in that wood to the sword.'
An ineffective volley rained on breastplate and helmet at the outset, and, encouraged by this ineffectiveness, Varallo urged forward his men-at-arms. Thus he brought them steadily within a range whereat arbalest bolt could pierce their protecting steel plates. But Bellarion, whose error in prematurely loosing the first volley was the fruit of inexperience, took no chances thereafter. He ordered his men to aim at the horses.
The result was a momentary check when a half-score of stricken chargers reared and plunged and screamed in pain and terror, and flung off as many riders to drown helplessly in their armour, weighed down by it and unable to regain their feet.
But Varallo, himself scatheless, urged them on with a voice of brass, and brought them after that momentary pause of confusion to the far bank. Here another dozen horses were brought down, and two or three men directly slain by bolts before Varallo had marshalled them and led them charging up and round the shallow hill, where the ascent was easy to the wood that crowned the bluff.
The whole of Buonterzo's army straggling along the left bank of the river cheered them lustily on, and the dominant cry that rang out clearly and boldly was 'No quarter!'
