Salūs sociōrum erat semper cāra Rōmānīs. Ōlim Gallī, amīcī Rōmānōrum, multās iniūriās ab Germānīs quī trāns flūmen Rhēnum vivēbant accēperant. Ubi lēgātī ab iīs ad Caesarem imperātōrem Rōmānum vēnērunt et auxilium postulāvērunt, Rōmānī magnīs itineribus ad hostium fīnīs properāvērunt. Mox ad rīpās magnī flūminis vēnērunt. Imperātor studēbat cōpiās suās trāns fluvium dūcere, sed nūllā viā poterat. Nūllās nāvīs habēbat. Alta erat aqua. Imperātor autem, vir clārus, numquam adversā fortūnā commōtus, novum cōnsilium cēpit. Iussit suōs in lātō flūmine facere pontem. Numquam anteā pōns in Rhēnō vīsus erat. Hostēs ubi pontem quem Rōmānī fēcerant vīdērunt, summō terrōre commōtī, sine morā fugam parāre incēpērunt.

The security of their allies was always dear to the Romans. Long ago the Gauls, the friends of the Romans, received many injuries from the Germans who lived across the Rhine river. When ambassadors from the Gauls came to Caesar, the Roman emperor, and asked for help, the Romans hastened across many roads to the land of their enemies. Soon they came to the banks of the great river. The emperor was eager to lead his troops across the river, but no way could be found. He also had no ships, and the water was high. The emperor, a brilliant man, never moved by adverse fortune, formed a new plan. He ordered his troops to build a bridge across the wide river. Never before had a bridge been seen across the Rhine. When the enemies saw the bridge which the Romans had built, they were moved to great terror, and immediately began to prepare their flight.
