No flag waved over it, and no sign of life appeared, not a canoe floated on the water, no sound was heard. Captain Hemming thought that had he not wished first to try pacific measures, he might have managed to surprise its garrison without resistance, but, like many another gallant man, he had no wish to fight if it could be avoided, and he only hoped to induce the Nicaraguans to yield without being compelled to resort to force. The gigs proceeded but slowly as the current here ran even faster than in any part of the river. Still no notice was taken of the boats, and Murray, who shared his captain's sentiments, had begun really to think that the matter would be settled without bloodshed, when two wreaths of smoke issued from the stockades, and a couple of shots whistled near them. At the same moment up went the flag of the Nicaraguan republic, and the next instant volleys of musketry came rattling by them from either side of the river. "Colonel Salas evidently does not intend to receive us as friends," observed Captain Hemming. "Order up the other boats, Murray, the sooner we give him and his followers the lesson they require the better. We will at once make a dash at the fort; it will not do to stop here and be shot down like dogs." As Dick Needham saw the flag run up he exclaimed-- "We'll have that bit of bunting down before long, lads, and it won't be my fault if I don't get hold of the halliards." The crews cheered and pulled on with renewed vigour. Their strength, however, was taxed to the utmost, for the banks of the river closing in at this point, the water rushed down like a mill-stream, and at times the boats remained almost stationary. It was no easy task to urge even the light boats ahead. Though showers of shot came rattling about them from numerous concealed foes on either side, it would have been useless to return their fire, for not an enemy showed himself.
