tubes, and the other the ammunition. On the night of the 2nd October, Miller led the van in the Galvarino, with the mortar in tow, the Pueyrredon followed, towing the ammunition. Then came the other two pontoons towed by the Araucano, Captain Hind, and the Independencia, Captain Charles. All the crews of the pontoons wore life belts.
The action was commenced by the mortar, which opened fire at less than eight hundred yards distance from the boom, and sunk a gunboat. But after throwing several shells into the batteries, the mortar bed broke away from its bearings, and no more could be done. The distance was too great for the rockets which fell harmlessly into the water, and under the heavy fire from the batteries it was impossible to run closer in. A red-hot shot struck the pontoon commanded by Hind, and caused an explosion by which twelve men were badly burned. The Galvarino was struck several times, and Lieutenant Bayley was cut in two by a shot. At dawn the pontoons were recalled. In a subsequent attack an attempt was made to destroy the boom by a fire-ship, but the wind dying away, she became a target for the enemy's guns; she was already sinking when the match was lighted by Lieutenant Morgall, and she blew up before reaching the boom.
The rockets were found to be so inefficient, that Cochrane desisted for the time from any further attempt[1].
The day after the last attack, a large ship was seen making for the port, which on sighting the Chilian squadron sheered off again. Cochrane followed, but taking her for a whaler, he returned to his anchorage and afterwards sailed to Arica. On his return he again saw the same ship, which sent a boat on shore. This ship was the 50-gun frigate Prueba, one of the vessels which had been reported to be on the way from Europe. Three had left Spain in company bound for Callao, but one being found to be unseaworthy, had put back on
