of April, was closely invested by land. The Turkish galleys would have
done the same by sea, had not the emperor been extremely vigilant, for
he caused the haven to be strongly chained from Constantinople to Pera,
having within the chain his whole strength of shipping. The Turks, on
the land side, erected towers, cast up trenches, and raised batteries;
from these works they carried on their attacks with great fury, and made
several breaches, which, however, the besieged repaired with much
industry, at the same time repulsing their enemies with artillery. This
unexpected bravery greatly enraged Mahomet, who loudly exclaimed, "It is
neither the Grecians' skill nor courage, but the Franks, that defend the
city." Affairs stood thus, when a renegado Christian informed the sultan
how he might bring part of his fleet over land to the very haven of
Constantinople. Mahomet, who began to despair of taking the city,
determined to put the project of the renegado into execution; and he
therefore committed the charge of it to a famous bassa, who, with
wonderful labour, brought seventy vessels out of the Bosphorus, up a
steep hill, the space of eight miles, to the haven of the city. The
Turks, being thus miraculously possessed of the haven, assaulted the
city also on that side; but their whole fleet was shamefully routed,
and ten thousand of their men were killed. Yet this loss, instead
of depressing their spirits, increased their courage, and on the
twenty-ninth of May, early in the morning, they approached the walls
with greater violence than ever; but so undaunted was the resolution
of the Christians, that they repulsed their assailants with prodigious
slaughter for a considerable time.

Constantine, however, who had undertaken the charge of one of the city
gates, unhappily received a wound in the arm; and, being obliged to
retire from the scene of action, his soldiers were discouraged, forsook
their stations, and fled after him, notwithstanding his earnest prayers
