ing embayed, but the handling
and superior sailing qualities of the _Pedro Primiero_ enabled her to
out-manoeuvre them and get clear. On seeing this, the Portuguese
squadron, finding further chase unavailing, gave us a broadside which
did no damage, and resumed its position in the van of the convoy, to
which we immediately gave chase as before, and as soon as night set in,
dashed in amongst them, firing right and left till the nearest ships
brought to, when they were boarded--the topmasts cut away--the rigging
disabled--the arms thrown overboard--and the officers compelled to give
their _parole_ not to serve against Brazil until regularly exchanged--an
event not likely to happen.

Keeping well up with them on the 5th--as soon as night set in, this mode
of attack was repeated, when we took a Russian vessel filled with
Portuguese troops, and disabled her in like manner. Of the merchantmen
within reach we took no notice, as it was impolitic to weaken the crew
of the flagship by manning prizes, whilst, as we saw nothing of the
remainder of the Brazilian squadron, there was no other means of
preventing their escape.

The prudence of preserving the crew of the flagship entire, was now well
exemplified. After taking possession of the Russian transport, at dusk,
I observed half-a-dozen large ships detach themselves from the main body
of the convoy, and suspecting some valid reason for the movement,
immediately gave chase. Though they crowded all sail, we came up with
them on the following morning, and singling out a large frigate-built
ship, filled with troops, we fired upon her till she brought to. On
boarding, we found her to be the _Gran Para_, containing--with the
others--a division of several thousand troops, destined to maintain
Portuguese authority in the province of Maranham--as, indeed, I had been
informed at Bahia. The private signals and instructions of the
Portuguese admiral--obtained by Flag-Lieutenant Grenfell from her
captain--put me in possession of the whole arrangement, which was thus
luckily frustrated.

As it was of importance not to let any of these troopships escape,
Captain Grenfell was ordered to disable the _Gran Para_, cutting away
her main and mizen masts, throwing the arms and ammunition overboard,
taking possession of the regimental flags, and compelling the officers,
as before, to give their _parole_ not to serve against Brazil. This
done, the other transports were successively boarded and disab
