Tunc pertimescens sollertissimus Caesar, ne observata nocte inluni, barbari gelu vinctum amnem pervaderent, cotidie a sole in vesperam flexo, ad usque lucis principium, lusoriis navibus discurrere flumen ultro citroque milites ordinavit, ut crustis pruinarum diffractis, nullus ad erumpendi copiam facile perveniret.
Then Caesar, being very shrewd and fearing that the savages might take advantage of some moonless night and cross the frozen river, gave orders that every day, from near sunset to the break of dawn, soldiers should row up and down stream in scouting vessels, so as to break up the cakes of ice and let no one get an opportunity of easy escape.
