Battle of Alesia
Caesar engaged in the Gallic Wars (58–50 BC), which led to his conquest of Gaul beyond Gallia Narbonensis. When the Helvetii, a federation of tribes from what is now Switzerland, planned a migration to the Atlantic coast through Gaul, Caesar went to Geneva and forbade the Helvetii to move into Gaul. While he went to Gallia Cisalpina to collect three other legions, the Helvetii attacked the territories of the Aedui, Ambarri, and Allobroges, three Gallic tribes, which called for Caesar’s help. Caesar and his Gallic allies defeated the Helvetii. The Gallic tribes then asked for Caesar to intervene against an invasion by the Suebi, a Germanic tribe. Caesar defeated the Suebi. In 57 BC he intervened in intra-Gallic conflicts and marched on the Belgae of northern Gaul. From then on he conquered the Gallic peoples one by one. His successes in Gaul brought Caesar political prestige in Rome and great wealth through the spoils of wars and the sale of war captives as slaves.
The Stolen Eagle
During the Siege of Alesia in 52 BC, Centurion Lucius Vorenus of the 13th Legion commands his men as Gallic warriors fall on his line. In contrast to the Gauls' chaotic charge, the Roman files fight with precision, until one drunk legionary, Titus Pullo, breaks ranks and charges into the crowd of Gauls. Vorenus angrily orders him back into formation, but Pullo hits him. Later, the assembled soldiers watch as Pullo is flogged and condemned to death for his disorderly conduct. The day after, Vercingetorix, "King of the Gauls", is brought before Julius Caesar and made to surrender, ending the eight-year-long Gallic Wars. Caesar's niece, Atia of the Julii, orders her son Octavian to deliver a horse she has purchased straight to Caesar in Gaul to ensure that he remembers them above all other well-wishers. Caesar himself receives news that his daughter, married to his friend Gnaeus Pompeius Magnus with whom he shares power in Rome, has died in childbirth along with her stillborn daughter. A blood tie broken between them, Caesar orders a new wife be found for Pompey.
