Gergovia (Gallic War).
Fought B.C. 52, between the Romans under Julius Cæsar, and the Gauls under Vercingetorix. Cæsar was besieging the town, but was compelled to retreat. Before retiring, however, he delivered an assault which was repulsed by the Gauls, the Romans leaving over 700 legionaries, and 46 centurions dead on the field.
