Did a Roman general's desperate gamble at the Long Causeways save his entire army?
In 15 AD, Roman general Aulus Caecina Severus faced annihilation in the marshes of Germania. Trapped by Arminius and his Germanic alliance, the Romans were forced into a chaotic retreat. A single, risky decision to abandon their baggage train ultimately allowed the legions to regroup and secure a hard-won victory.
The Battle at Pontes Longi occurred during a three-year campaign led by Germanicus. After an indecisive engagement, Caecina was ordered to march his forces back to the Rhine. His route was blocked by the 'long causeways,' a marshy area requiring extensive repairs. While his men worked, Arminius launched a fierce assault. The Roman legions were quickly separated, and Caecina himself nearly fell when his horse was killed beneath him, only surviving because the First Legion intervened.
The situation grew dire as the Romans struggled to maintain their lines. Recognizing that his troops were distracted by the need to protect their baggage carts and pack mules, Caecina ordered the supplies abandoned. This tactical sacrifice allowed the First and Twentieth legions to break free and rejoin the Fifth and Twenty-First on dry land. That night, panic nearly destroyed the army from within when a false rumor of a camp breach caused soldiers to stampede the gates. Caecina had to physically block the exit, throwing himself on the ground to force his men to stop and listen.
The final confrontation was decided by a disagreement among the Germanic leadership. Arminius advised waiting for the Romans to leave their camp, believing they would be easier to destroy in the open. However, his uncle Inguiomerus insisted on an immediate dawn assault. Outvoted, Arminius led the attack, but the Romans, their morale restored by Caecina, successfully repelled the offensive. The Germans fled, allowing Caecina to finish the repairs and return to the Rhine, an achievement for which he was later awarded triumphal honours.
The exact location of this battle remains a subject of intense academic debate. While some scholars point to excavations near Bramsche and log road remnants dated to 15 AD as evidence, others argue the site is too far from the Rhine. Alternative theories suggest the 'long bridges' were likely situated further southwest, between modern Münster and Coesfeld, aligning better with the distance to Roman garrisons at Xanten and Haltern.
