Arminius, retiring into pathless places, was pursued by Germanicus, who, as soon as he reached him, commanded the horse to advance and dislodge the enemy from the post he had possessed. Arminius, having directed his men to keep close together and draw near to the wood, wheeled suddenly about, and to those whom he had hid in the forest gave the signal to rush out. Then the Roman horse were thrown into disorder by the assault of a new army, and the cohorts sent out to support them, broken in upon by the body of troops that fled, had augmented the consternation, and were now being pushed into the morass--a place well known to the pursuers, but dangerous to those unacquainted with it--had not Germanicus drawn out the legions in order of battle. Hence the enemy became terrified, our men reanimated, and both retired without advantage on either side. Germanicus, soon after, returning with the army to the Amisia, reconducted the legions, as he had brought them, in the fleet; part of the horse were ordered to march along the sea-shore to the Rhine. Cæcina, who led his own men, was warned that, though he was to return through well-known roads, yet he should with all speed pass the causeway called the Long Bridges. It is a narrow causeway, between vast marshes, and formerly raised by Lucius Domitius. The rest of the country is of a moist nature, either tough and sticky from a heavy kind of clay or dangerous from the streams which intersect it. Round about are woods which rise gently from the plain, which at that time were filled with soldiers by Arminius, who, by short cuts and quick marching, had arrived there before our men, who were loaded with arms and baggage. Cæcina, who was perplexed how at once to repair the causeway decayed by time and to repulse the foe, resolved to encamp in the place, that while some were employed in the work, others might begin the fight.
