It was not long before this conspiracy was revealed.  The German control over the Cherusci had been aided by Segestus, a treacherous chief, whose beautiful and patriotic daughter, Thusnelda, had given her hand in marriage to Hermann, against her father’s will.  Filled with revengeful anger at this action, and hoping to increase his power, Segestus told the story of the secret meetings, which he had discovered, to Varus, and bade him beware, as a revolt against him might at any moment break out.  He spoke to the wrong man.  Pride in the Roman power and scorn of that of the Germans had deeply infected the mind of Varus, and he heard with incredulous contempt this story that the barbarians contemplated rising against the best trained legions of Rome.

Autumn came, the autumn of the year 9 A.D.  The long rainy season of the German forests began.  Hermann decided that the time had arrived for the execution of his plans.  He began his work with a deceitful skill that quite blinded the too-trusting Varus, inducing him to send bodies of troops into different parts of the country, some to gather provisions for the winter supply of the camps, others to keep watch over some tribes not yet subdued.  The Roman force thus weakened, the artful German succeeded in drawing Varus with the remainder of his men from their intrenchments, by inducing one of the subjected tribes to revolt.

The scheme of Hermann had, so far, been completely successful.  Varus, trusting to his representations, had weakened his force, and now prepared to draw the main body of his army out of camp.  Hermann remained with him to the last, dining with him the day before the starting of the expedition, and inspiring so much confidence in his faithfulness to Rome that Varus refused to listen to Segestus, who earnestly entreated him to take Hermann prisoner on the spot.  He even took Hermann’s advice, and decided to march on the revolted tribe by a shorter than the usual route, oblivious to the fact that it led through difficult mountain passes, shrouded in forests and bordered by steep and rocky acclivities.

The treacherous plans of the patriotic German had fully succeeded.  While the Romans were toiling onward through the straitened passes, Hermann had sought his waiting and ambushed countrymen, to whom he gave the signal that the time for vengeance had come.  Then, as if the dense forests had borne a sudden crop of armed men, the furious barbarians poured out in thousands upon the unsuspecting legionaries.

A frightful storm was raging.  The mountain torrents, swollen by the downpour of rain, over—­flowed their banks and invaded the passes, along which the Romans, encumbered with baggage, were wearily dragging onward in broken columns.  Suddenly, to the roar of winds and waters, was added the wild war-cry of the Germans, and a storm of arrows, javelins, and stones hurtled through the disordered ranks, while the barbarians, breaking from the woods, and rushing downward from the heights, fell upon the legions with sword and battle-axe, dealing death with every blow.
