It so happened that Turpin, who occasionally recalled to mind that he was Archbishop of Rheins, was at that time in the vicinity, making a pastoral visit to the churches under his jurisdiction. But his dignity of peer of France, and his martial spirit, which caused him to be reckoned among the "preux chevaliers" of his time, forbade him to travel without as large a retinue of knights as he had of clergymen. One of these was thirsty, and knowing the fountain on the borders of which Ogier was reposing, he rode to it, and was struck by the sight of a knight stretched on the ground. He hastened back, and let the Archbishop know, who approached the fountain, and recognized Ogier. The first impulse of the good and generous Turpin was to save his friend, for whom he felt the warmest attachment; but his archdeacons and knights, who also recognized Ogier, reminded the Archbishop of the oath which the Emperor had exacted of them all. Turpin could not be false to his oath; but it was not without a groan that he permitted his followers to bind the sleeping knight. The Archbishop's attendants secured the horse and arms of Ogier, and conducted their prisoner to the Emperor at Soissons. The Emperor had become so much embittered by Ogier's obstinate resistance, added to his original fault, that he was disposed to order him to instant death. But Turpin, seconded by the good Dukes Namo and Salomon, prayed so hard for him that Charlemagne consented to remit a violent death, but sentenced him to close imprisonment, under the charge of the Archbishop, strictly limiting his food to one quarter of a loaf of bread per day, with one piece of meat, and a quarter of a cup of wine. In this way he hoped to quickly put an end to his life without bringing on himself the hostility of the King of Denmark, and other powerful friends of Ogier. He exacted a new oath of Turpin to obey his order strictly. The good Archbishop loved Ogier too well not to cast about for some means of saving his life, which he foresaw he would soon lose if subjected to such scanty fare, for Ogier was seven feet tall, and had an appetite in proportion. Turpin remembered, moreover, that Ogier was a true son of the Church, always zealous to propagate the faith and subdue unbelievers; so he felt justified in practising on this occasion what in later times has been entitled "mental reservation," without swerving from the letter of the oath which he had taken. This is the method he hit upon. Every morning he had his prisoner supplied with a quarter of a loaf of bread, made of two bushels of flour, to this he added a quarter of a sheep or a fat calf, and he had a cup made which held forty pints of wine, and allowed Ogier a quarter of it daily.
