inciple, or, at least, colored by some pretext, of religion, freedom,
or loyalty. The leaders were nobles of independent property and
hereditary influence. The troops fought like men interested in the
decision of the quarrel; and as military spirit and party zeal were
strongly diffused throughout the whole community, a vanquished chief was
immediately supplied with new adherents, eager to shed their blood in
the same cause. But the Romans, after the fall of the republic,
combated only for the choice of masters. Under the standard of a popular
candidate for empire, a few enlisted from affection, some from fear,
many from interest, none from principle. The legions, uninflamed by
party zeal, were allured into civil war by liberal donatives, and
still more liberal promises. A defeat, by disabling the chief from the
performance of his engagements, dissolved the mercenary allegiance of
his followers, and left them to consult their own safety by a timely
desertion of an unsuccessful cause. It was of little moment to the
provinces, under whose name they were oppressed or governed; they were
driven by the impulsion of the present power, and as soon as that power
yielded to a superior force, they hastened to implore the clemency of
the conqueror, who, as he had an immense debt to discharge, was obliged
to sacrifice the most guilty countries to the avarice of his soldiers.
In the vast extent of the Roman empire, there were few fortified cities
capable of protecting a routed army; nor was there any person, or
family, or order of men, whose natural interest, unsupported by the
powers of government, was capable of restoring the cause of a sinking
party.

Yet, in the contest between Niger and Severus, a single city deserves an
honorable exception. As Byzantium was one of the greatest passages from
Europe into Asia, it had been provided with a strong garrison, and
a fleet of five hundred vessels was anchored in the harbor. The
impetuosity of Severus disappointed this prudent scheme of defence; he
left to his generals the siege of Byzantium, forced the less guarded
passage of the Hellespont, and, impatient of a meaner enemy, pressed
forward to encounter his rival. Byzantium, attacked by a numerous and
increasing army, and afterwards by the whole naval power of the empire,
sustained a siege of three years, and remained faithful to the name and
memory of Niger. The citizens and soldiers (we know not from what cause)
were animated with equ
