Twelve days after this rencontre, Nelson sailed at the head of an expedition against Teneriffe. A report had prevailed a few months before, that the viceroy of Mexico, With the treasure ships, had put into that island. This had led Nelson to meditate the plan of an attack upon it, which he communicated to Earl St. Vincent. He was perfectly aware of the difficulties of the attempt. "I do not," said he, "reckon myself equal to Blake; but, if I recollect right, he was more obliged to the wind coming off the land than to any exertions of his own. The approach by sea to the anchoring-place is under very high land, passing three valleys; therefore the wind is either in from the sea, or squally with calms from the mountains:" and he perceived that if the Spanish ships were won, the object would still be frustrated if the wind did not come off shore. The land force, he thought, would render success certain; and there were the troops from Elba, with all necessary stores and artillery, already embarked. "But here," said he, "soldiers must be consulted; and I know, from experience, they have not the same boldness in undertaking a political measure that we have: we look to the benefit of our country, and risk our own fame every day to serve her; a soldier obeys his orders, and no more." Nelson's experience at Corsica justified him in this harsh opinion: he did not live to see the glorious days of the British army under Wellington. The army from Elba, consisting of 3700 men, would do the business, he said, in three days, probably in much less time; and he would undertake, with a very small squadron, to perform the naval part; for though the shore was not easy of access, the transports might run in and land the troops in one day.
