Herrera listened, and from various quarters sounds that warned of approaching danger reached his ears. On one hand, although at a considerable distance, the clang of a cavalry trumpet was audible; on the other, church and convent bells rang out a tocsin of alarm. The sounds were taken up by other bells; in their rear, in front, on all sides. The Mochuelo rode along the flank of the little column, which in dead silence, and with rapid steps, followed El Tuerto, who, with Paco and Velasquez, marched at its head. So dim and shadowy did the dark figures of the guerillas appear, as they noiselessly strode along, that they might have been taken for the spectres of the slain, risen from some bloody battle field, and condemned to wander over the scene of their former exploits. With words of praise and encouragement the Mochuelo stimulated their progress. "Forward, men," he said, "steady and silent! Every moment is worth a million. There will be work for you before morning, but it is yet too soon." Full of confidence in their leader, undeterred by danger, but knowing the necessity of speed and prudence in their perilous position, the guerillas pressed on, keeping well together, and at a pace which it seemed almost impossible they should be able to sustain. They did sustain it, however; and, thanks to that circumstance, to the darkness, and to the skilful guidance of El Tuerto, to whom each tree and rock of that wild district was familiar, the Mochuelo's predictions were but partially realized. More than once, indeed, the adventurous little band were within a hair's-breadth of stumbling upon patrols and pickets of the enemy; more than once, whilst they lay upon their faces in the long fern, or stood concealed amongst trees, parties of cavalry rode by within pistol-shot; but nevertheless all encounters were happily avoided, and it was not till the first grey light of morning, and within a short league of Pampeluna, that they fell in with a Carlist battalion, occupied in posting the advanced pickets. Skirmishing ensued, and the Carlists, superior in number, pressed their opponents vigorously, until Herrera and the Mochuelo placed themselves at the head of the guerillas and charged with the bayonet. The Carlists gave way and were pursued for a short distance, when the Mochuelo, not deeming it prudent to follow them further, ordered the recall to be sounded. A quarter of an hour afterwards he and his men were safely under the cannon of Pampeluna.
