Our army formed immediately, and the duke posted the regiments as they came up so much to their advantage that Prince Eugene was obliged to alter his dispositions, and had this particular inconvenience upon his hands, viz., to attack an army superior to his own, in all their most advantageous posts; whereas, had he thought fit to have waited but one day, we should have met him half-way. But this was owing to the pride of the German generals, and their being so opinionated of the goodness of their troops. The royal army was posted with the left to the great river Po, on the other side of which the Prince of Vaudemont’s army lay cannonading the intrenchments which the imperialists had made at Borgo Fort; and hearing that there was like to be a general battle, he detached twelve battalions and about a thousand horse, to reinforce the royal army; all which, to our great encouragement, had time to join the army, while Prince Eugene was making his new dispositions for the attack. And yet it was the coming of these troops which caused Prince Eugene to resolve to begin the fight, expecting to have come to an action before they could come up. But he was disappointed in the reason of fighting, and yet was obliged to fight too, which was an error in the prince that it was too late to retrieve. It was five o’clock in the evening before he could bring up his whole line to engage; and then, after having cannonaded us to no great purpose for half-an-hour, his right, commanded by the Prince de Commercy, attacked our left wing with great fury. Our men received them so well and seconded one another so punctually that they were repulsed with a very great slaughter; and the Prince de Commercy being, unhappily for them, killed in the first onset, the regiments, for want of orders, and surprised with the fall of so great a man, were pushed into disorder, and one whole brigade was entirely broke. But their second line, advancing under General Herbeville, restored things in the first. The battalions rallied, and they came boldly on to charge a second time, and being seconded with new reinforcements from their main body, our men had their turn, and were pushed to a canal which lay on their left flank between them and the Po, behind which they rallied; and being supported by new troops, as well horse as foot, they fought on both sides with the utmost obstinacy, and with such courage and skill that it was not possible to judge who should have had the better could they have been able to have fought it out.
