besides his
infantry, was at the head of forty thousand horse. In this expedition,
Henry felt the difference between a hostile and a friendly country: the
remaining cities were preserved by his arms; and the savage, with
shame and loss, was compelled to relinquish his prey. The siege of
Thessalonica was the last of the evils which Calo-John inflicted or
suffered: he was stabbed in the night in his tent; and the general,
perhaps the assassin, who found him weltering in his blood, ascribed the
blow, with general applause, to the lance of St. Demetrius. [33] After
several victories, the prudence of Henry concluded an honorable peace
with the successor of the tyrant, and with the Greek princes of Nice and
Epirus. If he ceded some doubtful limits, an ample kingdom was reserved
for himself and his feudatories; and his reign, which lasted only ten
years, afforded a short interval of prosperity and peace. Far above the
narrow policy of Baldwin and Boniface, he freely intrusted to the Greeks
the most important offices of the state and army; and this liberality of
sentiment and practice was the more seasonable, as the princes of Nice
and Epirus had already learned to seduce and employ the mercenary valor
of the Latins. It was the aim of Henry to unite and reward his deserving
subjects, of every nation and language; but he appeared less solicitous
to accomplish the impracticable union of the two churches. Pelagius,
the pope's legate, who acted as the sovereign of Constantinople, had
interdicted the worship of the Greeks, and sternly imposed the payment
of tithes, the double procession of the Holy Ghost, and a blind
obedience to the Roman pontiff. As the weaker party, they pleaded
the duties of conscience, and implored the rights of toleration: "Our
bodies," they said, "are Caesar's, but our souls belong only to God." The
persecution was checked by the firmness of the emperor: [34] and if we
can believe that the same prince was poisoned by the Greeks themselves,
we must entertain a contemptible idea of the sense and gratitude of
mankind. His valor was a vulgar attribute, which he shared with ten
thousand knights; but Henry possessed the superior courage to oppose,
in a superstitious age, the pride and avarice of the clergy. In the
cathedral of St. Sophia he presumed to place his throne on the right
hand of the patriarch; and this presumption excited the sharpest censure
of Pope Innocent the Third. By a salutary edict, one of the firs
