ogress. The relaxed discipline of the Roman troops betrayed the most
important posts, where they were stationed, and the fear of deserved
punishment induced great numbers of them to enlist under the Gothic
standard. The various multitude of barbarians appeared, at length,
under the walls of Marcianopolis, a city built by Trajan in honor of
his sister, and at that time the capital of the second Maesia. The
inhabitants consented to ransom their lives and property by the payment
of a large sum of money, and the invaders retreated back into their
deserts, animated, rather than satisfied, with the first success of
their arms against an opulent but feeble country. Intelligence was soon
transmitted to the emperor Decius, that Cniva, king of the Goths, had
passed the Danube a second time, with more considerable forces; that his
numerous detachments scattered devastation over the province of Maesia,
whilst the main body of the army, consisting of seventy thousand Germans
and Sarmatians, a force equal to the most daring achievements, required
the presence of the Roman monarch, and the exertion of his military
power.

Decius found the Goths engaged before Nicopolis, one of the many
monuments of Trajan's victories. On his approach they raised the
siege, but with a design only of marching away to a conquest of greater
importance, the siege of Philippopolis, a city of Thrace, founded by the
father of Alexander, near the foot of Mount Haemus. Decius followed them
through a difficult country, and by forced marches; but when he imagined
himself at a considerable distance from the rear of the Goths, Cniva
turned with rapid fury on his pursuers. The camp of the Romans was
surprised and pillaged, and, for the first time, their emperor fled
in disorder before a troop of half-armed barbarians. After a long
resistance, Philoppopolis, destitute of succor, was taken by storm. A
hundred thousand persons are reported to have been massacred in the
sack of that great city. Many prisoners of consequence became a valuable
accession to the spoil; and Priscus, a brother of the late emperor
Philip, blushed not to assume the purple, under the protection of the
barbarous enemies of Rome. The time, however, consumed in that tedious
siege, enabled Decius to revive the courage, restore the discipline,
and recruit the numbers of his troops. He intercepted several parties
of Carpi, and other Germans, who were hastening to share the victory of
their countrymen,
