Our means being clearly inadequate to any decisive attack on the Spanish ships of war, I resolved to try the effect of an explosion vessel, and accordingly established a laboratory on the island of San Lorenzo, under the superintendence of Major Miller, the Commandant of Marines. Whilst engaged in this duty, that able and gallant officer was so severely burned by an accidental explosion, as to render his further services on this occasion unavailable.
On the 22nd of March—our preparations being completed—we again stood towards the batteries, the flag-ship going close in under the combined fire of the forts and shipping, in order to divert the attention of the enemy from the explosion vessel, which was set adrift in the direction of the frigates, but, unfortunately, when within musket shot of them, she was struck by a round shot and foundered, causing complete failure in our object. The San Martin and the Lautaro keeping far astern, there was no alternative but to withdraw from further attack, leaving the explosion vessel to her fate.
As other attempts, with our want of means, would answer no better purpose than useless demonstration, and as the ships were now destitute of water and provisions, we were obliged to fall back upon Huacho, leaving the Chacabuco to watch the movements of the enemy.
The inhabitants of Huacho, who were well disposed to co-operate in any effort for the emancipation of Peru, afforded us every assistance in provisioning and watering the ships, for which the commandant, Cevallos, shot two influential persons who had been foremost in aiding us, and severely punished others; at the same time seizing our water casks, and sending me an insolent letter of defiance, on which a party of seamen and marines was landed and put the garrison to flight; the officer commanding the party however withdrew from pursuit at hearing salutes fired on the arrival of Admiral Blanco with the Galvarino and Puyrredon, mistaking this for an engagement with a newly-arrived enemy. The whole of the Government property found in the Spanish custom-house was captured.
The people of Huacho having volunteered information that a quantity of specie belonging to the Philippine Company had been placed for safety on board a vessel in the river Barrança, she was forthwith overhauled, and the treasure transferred to the flag-ship.
Leaving Admiral Blanco at Huacho with the San Martin and Puyrredon, on the 4th of April we sailed for Supe, with the O'Higgins and Galvarino, having previously ascertained that a sum of money destined for the payment of Spanish troops was on its way from Lima to Guambucho; on the following day a party of marines being landed at Patavilca, captured the treasure, amounting to 70,000 dollars, together with a quantity of military stores. On the 7th, having received further information that the Philippine Company had placed other treasure on board the French brig, Gazelle, at Guambucho, we sailed for that place, and, on the 10th, the seamen of the O'Higgins examined her, and brought off an additional sum of 60,000 dollars.
The secret of our obtaining possession of these and other convoys of Spanish money along the coast, was, that I paid the inhabitants highly for information relative to their transmission, and was thus enabled to seize the treasure even in the interior of the country. As the Chilian Ministry subsequently refused to allow me "secret service money," these, disbursements were actually made at my own expense.
It was also my object to make friends of the Peruvian people, by adopting towards them a conciliatory course, and by strict care that none but Spanish property should be taken, whilst their own was in all cases respected. Confidence was thus inspired, and the universal dissatisfaction with Spanish colonial rule speedily became changed into an earnest desire to be freed from it. Had it not been for this good understanding with the inhabitants, I should scarcely have ventured to detach marines and seamen for operations at a distance into the country, as was subsequently the case; the people giving me the most reliable information of every movement of the enemy.
On the 13th, we arrived at Paita, where the Spaniards had established a garrison. A party of marines and seamen was again landed, on which the enemy fled from the fort, and a quantity of brass ordnance, spirits, and military stores, was captured.
Contrary to strict orders, some marines stole a number of valuable church ornaments, but on the complaint of the authorities I caused them to be restored, punishing the offenders, and at the same time presenting the priests with a thousand dollars to repair the damage done in their churches; this act, though far from conciliating the priests—who dreaded Chilian success—adding greatly to our popularity amongst the inhabitants, which was my object in bestowing the amount. Our thus refraining from plunder was almost beyond the comprehension of a people who had bitter experience of Spanish rapacity, whilst the undisciplined Chilenos, who formed the greater portion of the squadron, as little comprehended why their plundering propensities should be restrained.
