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.
