He was therefore compelled, in spite of his inferior numbers, to prepare for a pitched battle.
But it so happened that just when the preparations for a decisive engagement were being made on both sides, the Swiss Diet, learning that the sons of Helvetia were on the paint of cutting one another's throats, sent orders to all the Swiss serving in either army to break their engagements and return to the fatherland.

But during the two months that had passed between the surrender of Novarra and the arrival of the French army before the town, there had been a very great change in the face of things, because Ludovico Sforza's treasure was now exhausted.

New confabulations had gone on between the outposts, and this time, thanks to the money sent by Louis XII, it was the Swiss in the service of France who were found to be the better fed and better paid.

The worthy Helvetians, since they no longer fought far their own liberty, knew the value of their blood too well to allow a single drop of it to be spilled for less than its weight in gold: the result was that, as they had, betrayed Yves d'Alegre, they resolved to betray Ludovico Sforza too; and while the recruits brought in by the bailiff of Dijon were standing firmly by the French flag, careless of the order of the Diet, Ludovico's auxiliaries declared that in fighting against their Swiss brethren they would be acting in disobedience to the Diet, and would risk capital punishment in the end--a danger that nothing would induce them to incur unless they immediately received the arrears of their pay.

The duke, who a spent the last ducat he had with him, and was entirely cut off from his capital, knew that he could not get money till he had fought his way through to it, and therefore invited the Swiss to make one last effort, promising them not only the pay that was in arrears but a double hire.
But unluckily the fulfilment of this promise was dependent on the doubtful issue of a battle, and the Swiss replied that they had far too much respect for their country to disobey its decree, and that they loved their brothers far too well to consent to shed their blood without reward; and therefore Sforza would do well not to count upon them, since indeed the very next day they proposed to return to their homes.
