Second Battle of Bedriacum

The Battle of Bedriacum refers to two battles fought during the Year of the Four Emperors (69) near the village of Bedriacum (now Calvatone), about 35 kilometers (22 mi) from the town of Cremona in northern Italy. The fighting in fact took place between Bedriacum and Cremona, and the battles are sometimes called "First Cremona" and "Second Cremona".

Marcus Salvius Otho, with the support and aid of the Praetorian Guard, had his predecessor Galba murdered in January and claimed the throne for himself. However, legate Aulus Vitellius, governor of the province of Germania Inferior, had also claimed the throne earlier in the month and marched on Rome with his troops. Vitellius' forces were divided into two armies, one commanded by Aulus Caecina Alienus and the other by Fabius Valens. The Vitellian forces included legions XXI Rapax, V Alaudae and powerful vexillationes from all the other legions stationed on the Rhine, together with a strong force of Batavian auxiliaries, a force of around 70,000 in total. The forces commanded by Caecina crossed the Alps by the Great St. Bernard Pass to reach northern Italy. They attacked Placentia but were repulsed by the Othonian garrison and fell back on Cremona to await the arrival of Valens' army.

Otho left Rome on the March 14, and marched north to meet the challenge, leaving his brother Titianus in charge of Rome. He made his base at Brixellum. His forces included legions I Adiutrix, XIII Gemina, a forward detachment of XIIII Gemina, the Praetorian Guard and a force of gladiators. His general staff included generals such as Gaius Suetonius Paulinus, who, as governor of Britain, had defeated Boudica eight years before, but Otho decided to call his brother Titianus from Rome to act as his commander in chief.
