Having led back the army to the camp at the AMISIA (German: Ems), where the ships had been left behind, he (=GERMANICUS) ordered that the legions should be brought back the same way they had come. Part of his cavalry got orders to move along the coast of the ocean to the River Rhine. Although marching back on well-known tracks, CAECINA was told to cross the so-called LONG BRIDGES as soon as possible. These were a small footpath between swamps, built by L. DOMITIUS, a while ago. On both sides were some patches of wood rising up the hillsides, which were now occupied by ARMINIUS, who passed or anticipated our army, burdened with baggage and weapons. CAECINA was in trouble, for he didn't know how to fix the the log roads and to fight the enemy at the same time. Therefore, he made up his mind to set up a fortified camp. So, part of the army could work at the BRIDGES and the other part could fight.
