When the bridge was reached Severus ordered a small opening to be made in the barricade, through which only two men at a time could gain the left bank, and now, as the two last of the long train of burghers passed through--the bridge was still occupied by its original garrison--there sounded from the hills of the eastern forest, from the _right_ bank, the piercing cry of the black eagle. Cornelius quickly turned and looked towards the east. "Heardest thou the cry of the eagle?" Severus nodded. "A good omen for Roman warriors! Seest thou how our golden eagle on the standard seems to raise its wings?" But Cornelius did not look at the standard-bearer; he looked only towards the eastern forest. "A column of smoke rises up from the chamois rock." "A charcoal-burner! Turn thy face! In the _west_ stands the enemy. Lower the spears! Forward!" In two extended lines near each other, each three men deep, they now advanced towards the agile horsemen, who had quickly ridden back from the river as this mass of footmen passed over; they had halted half-way between the stream and the western forest, and had formed in two parallel lines. Only a spear's throw separated the enemies. Then as Severus and Cornelius, slowly advancing their columns, were just going to raise their spears, two Germans rode slowly towards them, ceremoniously turning the points of their lances downwards. "Halt!" cried Severus to his troops. "They wish to parley. Let us listen to them!" The two horsemen came now quite close to Severus and Cornelius. The combatants on each side stood back in anxious expectation.
