e with their hostile countrymen; to whom they imprudently,
or maliciously, revealed the weakness of the Roman empire. A soldier, of
the lifeguards of Gratian, was of the nation of the Alemanni, and of the
tribe of the Lentienses, who dwelt beyond the Lake of Constance. Some
domestic business obliged him to request a leave of absence. In a
short visit to his family and friends, he was exposed to their curious
inquiries: and the vanity of the loquacious soldier tempted him to
display his intimate acquaintance with the secrets of the state, and the
designs of his master. The intelligence, that Gratian was preparing to
lead the military force of Gaul, and of the West, to the assistance of
his uncle Valens, pointed out to the restless spirit of the Alemanni the
moment, and the mode, of a successful invasion. The enterprise of some
light detachments, who, in the month of February, passed the Rhine upon
the ice, was the prelude of a more important war. The boldest hopes
of rapine, perhaps of conquest, outweighed the considerations of timid
prudence, or national faith. Every forest, and every village, poured
forth a band of hardy adventurers; and the great army of the Alemanni,
which, on their approach, was estimated at forty thousand men by the
fears of the people, was afterwards magnified to the number of seventy
thousand by the vain and credulous flattery of the Imperial court. The
legions, which had been ordered to march into Pannonia, were immediately
recalled, or detained, for the defence of Gaul; the military command
was divided between Nanienus and Mellobaudes; and the youthful emperor,
though he respected the long experience and sober wisdom of the former,
was much more inclined to admire, and to follow, the martial ardor of
his colleague; who was allowed to unite the incompatible characters of
count of the domestics, and of king of the Franks. His rival Priarius,
king of the Alemanni, was guided, or rather impelled, by the same
headstrong valor; and as their troops were animated by the spirit of
their leaders, they met, they saw, they encountered each other, near the
town of Argentaria, or Colmar, [86] in the plains of Alsace. The
glory of the day was justly ascribed to the missile weapons, and
well-practised evolutions, of the Roman soldiers; the Alemanni, who long
maintained their ground, were slaughtered with unrelenting fury; five
thousand only of the Barbarians escaped to the woods and mountains; and
the glorious d
