Henry was now shut in on every side.  Poitou and Britanny were both in revolt.  The forts along the Sarthe, the Loir, and the Loire had fallen into the hands of Philip.  On the 30th of June his army was seen under the walls of Tours.  Henry himself was on the same day suddenly struck down by fever; unable to meet the French king, he fell back down the river to Saumur.  The great French princes, aghast at the swift catastrophe which had fallen, men scarcely knew how, on the Angevin king, trembling lest in this strange victory of the French monarchy his ruin should be the beginning of their own destruction, made a last effort for peace.  But Philip stood firm, “seeing that God had delivered his enemy into his hand.”  On Monday, the 3d of July, the walls of Tours fell before his assault, and he sent a final summons to Henry to meet him at Colombieres, a field near Tours.  The king travelled as far as the house of the Templars at Ballan.  But there he was seized with intolerable agony in every nerve of his body from head to foot.  Leaning for support against a wall in his extreme anguish, he called to him William the marshal, and the pitying bystanders laid him on a bed.  News of his illness was carried to the French camp.  But Richard felt no touch of pity.  His father was but feigning some excuse to put off the meeting, he told Philip; and a message was sent back commanding him to appear on the next day.  The sick king again called the marshal, and prayed him at whatever labour to carry him to the conference.  “Cost what it may,” he vowed, “I will grant whatever they ask to get them to depart.  But this I tell you of a surety, if I can but live I will heal the country from war, and win my land back again.”  With a final effort of his indomitable will he rode on the 4th of July through the sultry summer heat to Colombieres.  The great assembly gathered to witness the triumph of France was struck with horror at the marks of suffering on his face, and Philip himself, moved by a sudden pity, called for a cloak to be spread on the ground on which the king might sit.  But Henry’s fierce temper flashed out once more; he would not sit, he said; even as he was he would hear what they asked of him, and why they cut short his lands.  Then Philip stated his demands.  Henry must do homage, and place himself wholly at the French king’s mercy to do whatever he should decree.  Richard must receive, as Henry’s heir, the fealty of the barons of the lands on both sides the sea.  A heavy sum was to be paid to Philip for his conquests in Berri.  Richard and Philip were to hold Le Mans and Tours, and the other castles of Maine and Touraine, or else the castles of the Vexin, until the treaty was completely carried out.  Henry’s barons were to swear that they would force him to observe these terms.
