THE RE VOL UTIONAR Y PERIOD 183 fleet, Cochrane found that the authorities were slow to furnish him with necessary men and supplies, and dur- ing his whole brilliant career on the Pacific coast, he seemed to encounter much opposition to his plans and to be the object of much jealousy on the part of some of the Chilean officers, and even of San Martin himself. As many foreign officers had served in the Chilean army, and foreigners had been repeatedly honored, both in civil and rhilitary positions., we may suppose that Lord Cochrane's ideas of the campaign and San Martin's plans were sometimes at variance. 5an Martin wished to educate the Peruvians to the patriot cause, to win his way by mild measures so far as possible ■ Lord Cochrane wished to subdue rather than convert the Peruvian royalists. The year was occupied by the fleet in unimportant measures. Fireships were constructed and rockets prepared ; the latter being soldered with bell metal, burst at the first trial and were found to be of no value whatever. An expedition against Callao, with fire- ships and bell metal rockets, failed wholly of any sat- isfactory results, October 5th, 1819. The Spanish frig- ate "Prueba" arriving on the coast, Cochrane went in search of her to Arica, and not finding fier there, proceeded to Callao, having in the meantime dispatched two warships with a troop of soldiers under the com- mand of Colonels Charles and Miller to Pisco, which place was taken. The action, however, cost the life of Colonel Charles. Miller too was seriously wounded. Not finding the "Prueba" at Caiiao, Lord Cochrane went in search of her to Guayaquil. Proceeding up the Guayaquil river by night he captured two merchant- men, but the "Prueba" threw her guns and stores over- board and thus lightened, sailed up the river out of Cochrane's reach.
