When the gallant commander found that the heavy shot, grape, and musketry were riddling his vessel from stem to stern, he ordered the officers and men to go below, with the exception of those absolutely required on deck, in the hopes that they might thus escape injury. Scarcely, however, had they gone below, when two shots entered the gun-room, one of which killed Mr Barnes, clerk in charge, and the other Mr Webb, master’s assistant. Two seamen also were killed; and Mr Miller, assistant surgeon, and three men were wounded. As the wind and current were against her, and there was a great deal of water in the hold, she made but slow progress, and it was not till twenty-five minutes past one p.m. that she got out of fire. She received 7 shot between wind and water, besides 9 cannon, 14 grape, and 41 musket-balls in the hull and bulwarks, and 7 cannon and grape in the funnel and steam-pipe; while her boats, mainmast, and rigging were pierced through and through by round shot.

HM steam-sloop Alecto, Commander FW Austen, had previously, early in April, gone up, towing three heavily-laden schooners against a current of three knots and a head wind. On approaching a place called Tonelero, a number of workmen were seen throwing up batteries, clearly for the purpose of annoying the convoy on their way down. Opening her fire on them, she soon put the men to flight. She came up to the batteries on the morning of the 6th, with a strong wind and current against her, and the heavy schooners in tow. She had been accompanied all the way by a squadron of cavalry, who kept pace with her in an easy walk, halting every now and then. At two her crew went to quarters; and at forty minutes past two, having before fired a few shot, her three guns and rockets were got into full play. This was answered by the lower guns on the batteries with round shot until she reached the narrowest part, when the enemy opened with round shot and grape together. Their guns were raking her at this time from head to stern in such a way that none of her guns could be brought effectually to bear on them. In this state she remained for twenty minutes, scarcely going ahead, and receiving the fire of seven eighteen-pounders, several of which were pointed down on her decks. During this time she fired away in return at the enemy, who appeared abreast of her, every charge of grape and canister on board, and was then reduced to round shot. For a few minutes, also, she exchanged with them a sharp fire of musketry. She then went gradually ahead, and as the river widened, and the current decreased in strength, she drew out of shot, having been an hour and fifteen minutes under fire.

Captain Austen, her commander, was the only person hurt, a spent grape-shot having struck him a severe blow on the thigh. Commander Mackinnon, then a lieutenant, who has written a most amusing account of the affair, says “that in going into action the men appeared to take it as a matter of course; but as the plot thickened and they warmed at the work, they tossed the long guns about like playthings, and indeed managed them in an admirable manner.” This he attributes to the system taught on board the Excellent.

The crews of the Monte Videan schooners were in a dreadful fright all the time, expecting to be sent to the bottom. On sounding the well on board the Alecto, a considerable quantity of water was found in the hold. When search was made, a shot-hole was discovered forward, between wind and water. This was speedily plugged. Just as she came in sight of the convoy, after her long and tedious voyage, she got on shore, and there remained for some days before she was again floated off.

Gallant exploit of a rocket-battery.

Santa Fé is situated on the east bank of the river. It is a place of some size. Built partly at the foot and partly on the side of a lofty hill, surrounded by corrales where thousands of cattle are slaughtered, their hides and their tallow being shipped from the port, while vast flocks of vultures, carrion crows, and other birds of prey hover over them to consume the refuse beef, which there are not human mouths sufficient to eat. As may be supposed, it is far from an agreeable place. The greater part of the English and French men-of-war were lying at Baxadar de Santa Fé, which was the appointed rendezvous of the merchantmen. Here the larger number, having effected their object, collected towards the middle of May. The difficulty was now to get the convoy safely back past the batteries of San Lorenzo. Sir Charles Hotham had got up to settle some diplomatic affairs with the Government of Corrientes, and on the 16th of May he returned in the Alecto.

A plan had occurred to Lieutenant Mackinnon of that ship, by which the passage of the convoy might be facilitated; and, having proposed it to Sir Charles Hotham, he, after a short consideration of its possibility, expressed his willingness to have it carried out, should everything be as supposed.

Lieutenant Mackinnon stated that opposite to the heavy part of the batteries of San Lorenzo he had observed an island covered with long reeds, grass, and small trees, but completely commanded by the guns of the battery. He proposed, the night before the convoy was to fight their way down, to take on shore a certain number of congreve rockets, to land them at the back of the island, and to place them in readiness for use when the time of action should arrive; this could be effected in a few minutes,—then to dig by the side of each rocket a hole large enough to contain the men working them, and to throw the earth up as a kind of barricade before it; at the signal given by the commander-in-chief, when all the enemy’s batteries were fully manned, waiting for the convoy, to commence a tremendous fire of rockets, which, being totally unexpected by the enemy, would be proportionally effective and destructive. The chances were that they would return this fire, which the prepared holes would render harmless; and if the rocket-stands or tubes were hit,—very difficult objects,—poles and instruments would be at hand to repair them immediately. Besides, when the vessels were passing, the chances were that, from the height of the cliffs, the rockets would strike the enemy over the mast-heads of the ships, thus causing a double-banked fire of great force.

Sir Charles Hotham having consulted Captain Hope and Captain Trehouart, who highly approved of the plan, provided the ground when reconnoitred was found as suitable as expected, the execution of it was entrusted to Lieutenant Mackinnon, of the Alecto, with Lieutenant Barnard, of the Firebrand, as his second. For several days the preparations were going on; and on the 25th of May, all being ready, the convoy and men-of-war dropped down the river, and anchored about five miles above the batteries of San Lorenzo, while the Alecto, continuing her course, brought up still nearer to them.

At length, on the night of the 1st of June, Sir Charles Hotham and the French captain, with some other officers, reconnoitred the locality. Besides the island we have spoken of, there were several others of nearly the same size, and at the same distance from the western shore; to the eastward of them, again, was an immense archipelago of low swampy islands, covered with brushwood, extending in that direction six or eight miles between them and the main shore of Entre Rios.
