Cause

During the Social War, Italian allied peoples revolted against Rome seeking citizenship rights. Roman consul Lucius Julius Caesar led an army of 35,000 men through the region, creating an opportunity for Italian rebel commander Marius Egnatius to exploit a vulnerable march through a narrow defile.

Event

As Lucius Caesar's army passed through a defile near Taenum, Marius Egnatius launched an ambush. Despite suffering heavy initial losses, the Romans fought their way out in a desperate retreat to the town of Teanum, where they took up a defensive position. Caesar himself, gravely ill, had to be carried from the field on a litter.

Consequence

The battle resulted in approximately 8,000 Roman dead and a significant morale blow for Rome. The rebel victory at Taenum offset the Italian forces' prior defeat at Acerrae, helping to sustain the Italian rebel cause during the Social War.
