Richard from captivity.

His escape was very critical.

Henry had been detected in the assassination of the bishop of Liege, and in an attempt of a like nature on the duke of Louvaine; and finding himself extremely obnoxious to the German princes on account of these odious practices, he had determined to seek support from an alliance with the king of France; to detain Richard, the enemy of that prince, in perpetual captivity; to keep in his hands the money which he had already received for his ransom; and to extort fresh sums from Philip and prince John, who were very liberal in their offers to him.

He therefore gave orders that Richard should be pursued and arrested; but the king, making all imaginable haste, had already embarked at the mouth of the Schelde, and was out of sight of land when the messengers of the emperor reached Antwerp.
The joy of the English was extreme on the appearance of their monarch, who had suffered so many calamities, who had acquired so much glory, and who had spread the reputation of their name into the farthest east, whither their fame had never before been able to extend.

He gave them, soon after his arrival, an opportunity of publicly displaying their exultation, by ordering himself to be crowned anew at Winchester; as if he intended, by that ceremony, to reinstate himself in his throne, and to wipe off he ignominity of his captivity.
