Gallic Wars
The Gallic Wars were a series of military campaigns waged by the Roman proconsul Julius Caesar against several Gallic tribes. Rome's war against the Gallic tribes lasted from 58 BC to 50 BC and culminated in the decisive Battle of Alesia in 52 BC, in which a complete Roman victory resulted in the expansion of the Roman Republic over the whole of Gaul (mainly present-day France and Belgium). While militarily just as strong as the Romans, the internal division between the Gallic tribes helped ease victory for Caesar, and Vercingetorix's attempt to unite the Gauls against Roman invasion came too late. The wars paved the way for Julius Caesar to become the sole ruler of the Roman Republic.
Battle of Sena Gallica (551)
The Battle of Sena Gallica, was a naval battle fought off the Italian Adriatic coast in the autumn of 551 between an East Roman (Byzantine) and an Ostrogoth fleet, during the Gothic War (535–554). It marked the end of the Goths' brief bid to deny the seas to the Romans, and the beginning of the Byzantine resurgence in the war under the leadership of Narses.
