Naissus (Gothic Invasion of the East).
Fought 269 between the Imperial troops, under the Emperor Claudius Gothicus, and the invading Goths. The Romans were hard pressed, when the Gothic lines were attacked in the rear by a force of 5,000 men, which Claudius had concealed for this purpose in the neighbouring mountains, and being thrown into confusion, were totally routed. Fifty thousand men are said to have fallen in the battle.
