The command of the frigate had been given to Captain Guise; and after her change of name, his officers wrote to him a letter deprecating the name, and alleging, that as they had nothing to do with the conquest of Valdivia, it ought to be withdrawn, and one more consonant with their feelings substituted. This letter was followed by marked personal disrespect towards myself, from the officers who had signed it, who made it no secret that the name of Guise was the one sought to be substituted.

As the conversations held by these officers with the rest of the squadron were of such a derogatory nature as regarded my character and authority, as might lead to serious disorganization, I brought the whole of the officers who had signed the letter to a court-martial, two being dismissed the service, the remainder being dismissed the ship, with a recommendation to General San Martin for other appointments.

During the arrest of these officers, I had determined upon an attack upon the fortifications of Callao, intending to carry them by a coup de main, similar to that which had succeeded at Valdivia, and having, on the 18th, taken soundings in the Potrillo, was convinced of the feasibility of the plan.

On the 20th, this intention was notified by an order, stating that on the following day I should make the attack with the boats of the squadron and the San Martin, the crew of which received the order with loud cheers, volunteers for the boats eagerly pressing forward from all quarters.

In place of preparing to second the operations, Captain Guise sent me a note refusing to serve with any other but the officers under arrest—stating that unless they were restored, he must resign his command. My reply was that I would neither restore them nor accept his resignation, without some better reason for it than the one alleged. Captain Guise answered, that my refusal to restore his officers was a sufficient reason for his resignation, whereupon I ordered him to weigh anchor on a service of importance; the order being disobeyed on the ground that he could no longer act, having given over the command of the ship to Lieutenant Shepherd. Feeling that something like a mutiny was being excited, and knowing that Guise and his colleague, Spry, were at the bottom of the matter, I ordered the latter to proceed with the Galvarino to Chorillos, when he also requested leave to resign, as "his friend Captain Guise had been compelled so to do, and he had entered the Chilian navy conditionally to serve only with Captain Guise, under whose patronage he had left England." Such was the state of mutiny on board the Galvarino, that I deputed my flag-captain, Crosbie, to restore order, when Spry affected to consider himself superseded, and claimed exemption from martial law. I therefore tried him by court-martial, and dismissed him from the ship.

The two officers now made their way to head-quarters, where General San Martin immediately made Spry his naval aide-de-camp, thus promoting him in the most public manner for disobedience to orders, and in defiance of the sentence of the court-martial; this being pretty conclusive proof that they had been acting under the instructions of General San Martin himself, for what purpose will appear in the course of the narrative. The course now pursued by General San Martin sufficiently showed that the disturbance previously made at Valparaiso emanated also from himself, and that in both cases the mutinous officers felt quite secure in his protection; though I will do both the credit of supposing them ignorant at the time of the treacherous purposes of which they were afterwards the instruments.

Knowing that I should take their punishment into my own hands if they returned to the squadron, General San Martin kept both about his own person at head-quarters, where they remained.

So dissatisfied were the Spanish troops at Lima with the government of their Viceroy, Pezuela, to whose want of military capacity they absurdly attributed our successes, that they forcibly deposed him, after compelling him to appoint General Lacerna as his successor. The deposed Viceroy wishing to send his lady and family to Europe, applied to General San Martin for a passport, to avoid capture by the Chilian squadron. This was refused; but Lady Cochrane having arrived at Callao in the British frigate Andromache, to take leave of me previous to her departure for England, the Viceroy's lady, Donna Angela, begged of her Ladyship to use her influence with the General to obtain leave for her departure for Europe. Lady Cochrane immediately proceeded to Haura, and effected the object; after which she remained for a month at head-quarters, residing at the house of a Peruvian lady, Donna Josefa Monteblanco.

A passage was also, by Lady Cochrane's influence, procured for the lady in the Andromache, on board which ship Captain Sherriff politely invited me to meet her. At this interview the ex-Vicequeen expressed her surprise at finding me "a gentleman and rational being and not the ferocious brute she had been taught to consider me!" A declaration, which, from the unsophisticated manner in which it was made, caused no small merriment in the party assembled.

As I was determined not to be idle, General San Martin was with some difficulty prevailed upon to give me a division of 600 troops, under the command of Lieutenant-Colonel Miller. On the 13th of March we sailed for Pisco, of which, on its previous abandonment by the army, after a useless sojourn of fifty days, the enemy had again taken possession. On the 20th it was retaken, when it was found that the Spaniards had severely punished the alleged defection of the inhabitants for contributing to the supplies of the patriot force during its stay. Not imagining that we should return, the Spanish proprietors of estates had brought back their cattle, of which we managed to seize some 500 head, besides 300 horses for the use of the Chilian forces, the squadron thus supplying their wants instead of remaining in total inaction.
