On the 5th of May, I proceeded with the flag-ship alone to reconnoitre Callao, having learned that the Chacabuco and Puyrredon had been chased off the port by the Spanish frigates. Finding that these were again moored under shelter of the batteries, we returned to Supe, convinced that our previous visit to Callao had proved sufficient to deter them from putting to sea for the protection of their own coasts; this, indeed, forming my chief reason for having persisted in attacks which, with our small force, could answer no other purpose; but this alone was an advantage gained, as it enabled us to communicate freely with the inhabitants on the coast, and to ascertain their sentiments, which—from our forbearance, no less than command of the sea—were almost uniformly in favour of co-operation with Chili for their emancipation.
Both at Lima and on the coast, the best effect was produced by the circulation of the following proclamation:—
"Compatriots! The repeated echoes of liberty in South America have been heard with pleasure in every part of enlightened Europe, more especially in Great Britain, where I, unable to resist the desire of joining in such a cause, determined to take part in it. The Republic of Chili has confided to me the command of her naval forces. To these must the dominion of the Pacific be consigned. By their co-operation must your chains be broken. Doubt not but that the day is at hand on which, with the annihilation of despotism and your now degraded condition, you will rise to the rank of a free nation, to which your geographical position and the course of events naturally call you."
"But it is your duty to co-operate in preparing for this success, and to remove obstacles, under the assurance that you will receive the most efficacious assistance from the government of Chili, and your true friend, COCHRANE."
This proclamation was accompanied by another from the Chilian government, declaratory of the sincerity of its intentions, so that these combined caused us to be everywhere received as liberators.
On the 8th, we returned to Supe, and having learned that a Spanish force was in the vicinity, a detachment of marines and seamen was, after dark, pushed through a heavy surf, and landed, in the hope of taking them by surprise. But the enemy was on the alert, and on the following morning our little party fell into an ambuscade, which would have proved serious, had not Major Miller, who commanded the marines, promptly formed his men, who, attacking in turn, soon put the enemy to flight at the point of the bayonet, capturing their colours, and the greater portion of their arms. On the 13th, a detachment of Spanish troops arrived from Lima under Major Camba, who, notwithstanding his superiority of numbers, did not venture to attack our small party, which withdrew to the ships with a number of cattle taken from the Spaniards; Camba writing to the Viceroy so effective a description of his having "driven the enemy into the sea," that he was immediately promoted.
Not to enter into further details of our visits to other parts of the coast, where similar captures of provisions and military stores, &c. were effected—it being my practice to compel the Spaniards to supply all the wants of the squadron, nothing being ever taken from the natives without payment,—I resolved—as our means were clearly incommensurate with our main object—to return to Valparaiso, for the purpose of organizing a more effective force, and on the 16th of June reached that port, where we found Admiral Blanco with the San Martin and Chacabuco, he having been obliged to raise the blockade of Callao for want of provisions; a step with which the Government was highly displeased, though with more reason to blame its own negligence or want of foresight in not providing them. Admiral Blanco was nevertheless put under arrest, but a court of inquiry being held, he was honourably acquitted.
The objects of the first expedition had been fully accomplished, viz. to reconnoitre, with a view to future operations, when the squadron should be rendered efficient; but more especially to ascertain the inclinations of the Peruvians with regard to their desire for emancipation—a point of the first importance to Chili, as being obliged to be constantly on the alert for her own newly-acquired liberties, so long as the Spaniards were in undisturbed possession of Peru. To the accomplishment of these objects had been superadded the restriction of the Spanish naval force to the shelter of the forts, the defeat of their military forces wherever encountered, and the capture of no inconsiderable amount of treasure.
It had, however, become evident to me that the passive system of defence which the Spaniards adopted in Callao, would render it a difficult matter to get at them without more effective means than the guns of the ships, which were greatly inferior in number to those of the enemy's fortress and shipping combined, whilst their experience in the use of artillery was greater than that of our crews. The Supreme Director having paid a visit to the squadron—on the 21st of June I addressed to him a letter, stating my apprehension that the finances of the Government might be limited, and that I would gladly give up to the exigencies of the Republic the whole of my share of prize-money taken during our recent cruize, provided it were applied to the manufacture of rockets. This offer was declined, with a compliment from the Supreme Director, on the advantage already gained, by compelling the Spaniards ignominiously to shut "themselves up in their port, in spite of their numerical superiority."
Complimentary addresses from the Chilian people were also presented to me in profusion, and a public panegyric was pronounced at the National Institute of the capital, upon the service rendered; but as this was only a recapitulation of what has been already narrated—conveyed in flowery rhetorical phrases—in the use of which the Occidentals are almost as expert, and often as exaggerated, as are the Orientals—I shall refrain from giving it. Suffice it to say, that the people were not a little delighted with the plain facts, that whereas only a few months before theirs had been the blockaded port, they were now able to beard the enemy in his stronghold, till then believed—both by Spaniards and Chilians—to be inviolable; and that, with only four ships on our part, the Spanish Viceroy had been shut up in his capital, and his convoys, both by sea and land, intercepted, whilst his ships of war did not venture to emerge from their shelter under the batteries of Callao.
