In all civilized hostility, a treaty is established for the exchange or ransom of prisoners; and if their captivity be prolonged, their condition is known, and they are treated according to their rank with humanity or honor. But the savage Bulgarian was a stranger to the laws of war: his prisons were involved in darkness and silence; and above a year elapsed before the Latins could be assured of the death of Baldwin, before his brother, the regent Henry, would consent to assume the title of emperor. His moderation was applauded by the Greeks as an act of rare and inimitable virtue. Their light and perfidious ambition was eager to seize or anticipate the moment of a vacancy, while a law of succession, the guardian both of the prince and people, was gradually defined and confirmed in the hereditary monarchies of Europe. In the support of the Eastern empire, Henry was gradually left without an associate, as the heroes of the crusade retired from the world or from the war. The doge of Venice, the venerable Dandolo, in the fulness of years and glory, sunk into the grave. The marquis of Montferrat was slowly recalled from the Peloponnesian war to the revenge of Baldwin and the defence of Thessalonica. Some nice disputes of feudal homage and service were reconciled in a personal interview between the emperor and the king; they were firmly united by mutual esteem and the common danger; and their alliance was sealed by the nuptials of Henry with the daughter of the Italian prince. He soon deplored the loss of his friend and father. At the persuasion of some faithful Greeks, Boniface made a bold and successful inroad among the hills of Rhodope: the Bulgarians fled on his approach; they assembled to harass his retreat. On the intelligence that his rear was attacked, without waiting for any defensive armor, he leaped on horseback, couched his lance, and drove the enemies before him; but in the rash pursuit he was pierced with a mortal wound; and the head of the king of Thessalonica was presented to Calo-John, who enjoyed the honors, without the merit, of victory. It is here, at this melancholy event, that the pen or the voice of Jeffrey of Villehardouin seems to drop or to expire; 31 and if he still exercised his military office of marshal of Romania, his subsequent exploits are buried in oblivion. 32 The character of Henry was not unequal to his arduous situation: in the siege of Constantinople, and beyond the Hellespont, he had deserved the fame of a valiant knight and a skilful commander; and his courage was tempered with a degree of prudence and mildness unknown to his impetuous brother. In the double war against the Greeks of Asia and the Bulgarians of Europe, he was ever the foremost on
