Vercingetorix's Gauls threw back Caesar's assault on the Arverni hill town of Gergovia in central France in 52 BC.
See it on the Battles & Wars map →What happened
Caesar besieged Gergovia, near modern Clermont-Ferrand, with six legions. The town sat on a high plateau too strong to storm, and his Aedui allies were wavering. He staged a feint to seize nearby high ground, but his troops pushed on uphill to the town walls without orders and were thrown back when Gallic reinforcements arrived. Caesar reported nearly 700 dead, including 46 centurions (company officers), blamed his soldiers' over-eagerness, and lifted the siege.
Why it matters
The victory drew more tribes, including Rome's long-time allies the Aedui, into the revolt, but it also set up the siege of Alesia that ended Gaul's independence.
How we know
Caesar's Gallic War, Book 7; digs on the Gergovie plateau, begun under Napoleon III in the 1860s and resumed since the 1990s, that found Roman camps, ditches and weapons.
Still debated
Caesar may have played down the scale of his loss, and the exact course of the assault is reconstructed mainly from his account.

▸Vercingetorix defeated Caesar at Battle of GergoviaWell documented
The connection
Vercingetorix shadowed Caesar to Gergovia, the chief town of his own Arverni, and camped on the heights around it. When Roman troops pressed an unplanned assault up the slopes, his forces counterattacked and drove them back. Caesar withdrew, and the victory strengthened Vercingetorix's position as the revolt's leader.
When and how
Gergovia, near Clermont-Ferrand in central France, spring or early summer 52 BC.
How we know
Caesar himself admits the defeat in Book 7 of his Gallic War, and digs on the Gergovie plateau found Roman camps and fortifications.
Debates and open questions
How much the victory owed to Vercingetorix's planning versus Roman indiscipline, as Caesar claims, cannot be checked against any Gallic account.
▸Julius Caesar suffered his one personal defeat in Gaul at Battle of GergoviaWell documented
The connection
Caesar tried to take Gergovia by a ruse: a feint drew Gallic defenders away while his legions seized ground below the town. His troops ignored the recall signal, attacked the walls and were driven back. It was the only defeat he suffered in Gaul in a battle he personally commanded, and he lifted the siege.
When and how
Gergovia, central France, spring 52 BC; Caesar with six legions against Vercingetorix's Gauls.
How we know
Caesar's own account admits nearly 700 dead, including 46 centurions, and blames his soldiers' eagerness; archaeology confirms the Roman camps.
Debates and open questions
Caesar may have played down his losses. The ambush at Atuatuca in 54 BC killed more Romans, but under his deputies, so 'worst defeat' depends on how one counts.
