The Sienese prepared for defence, while messenger after messenger was sent to stay the Borgia's advance. At first all orders seemed united to defend Pandolfo, "with such love and charity," wrote the Balìa, "as has never been shown in any other occurrence in this city." The mob shouted lustily for "Lupa, Libertà e Pandolfo." But Cesare came nearer and nearer, sending an ultimatum before him, bidding the Sienese expel Pandolfo, dismiss Giampaolo Baglioni and his men, and surrender their artillery. Then the hearts of the Sienese began to sink; there were countrymen of theirs in the hostile camp, and Leonardo Bellanti was vigorously fanning the flames among the citizens. Pandolfo sent his children to a place of safety. At length, on January 24th, the Balìa, in Pandolfo's presence, decreed his exile, and appointed six citizens to come to an agreement with Cesare. But already the people had risen in tumult at the sight of the two Borgian envoys and the rumoured approach of his cavalry, and Pandolfo still lingered. Then there came another letter from Cesare from Pienza: "We swear to God that if, in whatever hour you shall receive these presents, you shall not have already expelled, or shall not immediately without further delay expel the said Pandolfo, we shall reckon every one of you in the place of Pandolfo. And without any intermission we shall move to the total extermination of all your towns, subjects, and goods, and of your city and of your own persons. Since you choose to be our enemies, you shall remain beaten down and crushed in such wise that never again shall you be able to offend us."[55] This settled it. On the evening of January 28th, Pandolfo and Giampaolo took a solemn farewell of the government and left Siena. As the Magnifico rode from the Palazzo his adherents crowded round him, weeping and profuse in their anticipations of his speedy return. But a woman shrieked at him from a window: "Crucify him! crucify the traitor!" It was the mother of a certain Ildebrando Cerretani, who had been secretly murdered at Pandolfo's bidding. He made his way in disguise to Lucca, closely pursued by a band of Borgia's light-armed cavalry, who (in spite of Cesare's safe conduct to Pandolfo) had orders to cut both him and Giampaolo to pieces.
