The naval force which accompanied General Heideck was unusually powerful, as he was then the acknowledged agent of the King of Bavaria. It consisted of the frigate Hellas of sixty-four guns, with the flag of Admiral Miaoulis, the Karteria, and some smaller vessels as transports. The Greek vessels arrived before Oropos in the afternoon, and as the Hellas was compelled to anchor about a mile from the Turkish camp, Captain Hastings immediately steamed into the port. He captured two transports laden with grain and flour, which had just arrived from Negropont; and having anchored within two hundred yards of the Turkish batteries, he opened on them a fire, which in a short time dismounted every gun which they could bring to bear on his ship. A carcass-shell lodging in the fascines of which the principal battery was constructed, soon enveloped the whole in flames—the powder-magazine exploded, and the carriages of the guns were rendered useless.

At this moment the Greek troops, of whom one hundred and fifty were on board the Karteria, loudly demanded to be led to attack the camp; and an officer from General Heideck, who had remained on board the Hellas, was expected every moment to place himself at their head. No orders, however, arrived. Hastings remained all night in the port, and it was not until dawn next morning that the troops were landed. The Turks, in the mean time, had been more active; they had also received considerable reinforcements; the day was consumed without General Heideck going on shore, and a large body of Turkish cavalry making its appearance in the afternoon, he issued orders to re-embark the troops, and sailed back to Egina.

The public attention was suddenly diverted from this disgraceful exhibition of European military science by the arrival of Lord Cochrane in Greece. He came, however, in an English yacht, which had been purchased to expedite his departure, but unaccompanied by a single one of the five steamers which were still unfinished in the Thames. His lordship was soon after appointed lord high admiral of Greece; General Church was at the same time named generalissimo of the land forces; and both officers directed all their attention to raising the siege of Athens, which Kutayhi continued to attack with the greatest constancy.

Captain Hastings was now detached for the first time with an independent naval command. The Turks drew their supplies for carrying on the siege of Athens from a great distance in their rear, as all the provinces of Greece were in a state of desolation. This circumstance exposed their lines of communication, both by land and sea, to be attacked by the Greeks in many different points. Volo was one of the principal depots at which the supplies transmitted from Thessalonica and Constantinople were secured; and from this station they were forwarded by the channel of Eubœa to the fortress of Negropont, and thence to Oropos. From Oropos these supplies were transported on horses and mules to the camp of the Pasha at Patissia, near Athens. Captain Hastings was now charged with the duty of cutting off the communications of the Turks between Volo and Oropos, and instructed to use every exertion to capture their transports and destroy their magazines. For this purpose he sailed from Poros with a small squadron, consisting of the Karteria and four hired vessels—the corvette Themistocles, belonging to the Tombazis; the Ares, belonging to the Admiral Miaoulis; and two small schooners.

On the afternoon of a beautiful clear day, the little fleet entered the bay of Volo, in which eight Turkish transports were seen at anchor. It was some time before the enemy was persuaded that the Greek vessels were bearing down to attack them, for they considered the anchorage perfectly defended by two batteries which they had erected on the cape, enclosing the harbour, opposite the castle of Volo. The castle itself is a square fort in a dilapidated condition, with only a few guns mounted.

At half-past four o'clock, the Themistocles and Ares received orders to anchor before the batteries, just out of the reach of musketry, and not to waste a single shot before they had taken up their positions. They were then directed to open a heavy fire of grape and round shot on the enemy. While they were executing these orders, Hastings entered the port, and opened his fire of shells on the intrenchments of the Turks, and of grape on the transports, which were filled with men to prevent their capture. The heavy fire of the Karteria, which poured on the enemy three hundred two-ounce balls from each of its guns, soon threw the Turks into confusion; and the boats were manned, and sent to board the transports. Five vessels being heavily laden, though they had been run aground, were not close to the shore, and these were soon captured; but two brigs being empty, were placed close under the fire of the troops in the intrenchments. Though they were attacked by all the boats of the squadron, they were not taken until after an obstinate resistance. The English boatswain of the Karteria, who was the first to mount the side of one, was wounded; but he succeeded in gaining the deck, and hauling down the Turkish flag. A Turk, however, who had no idea of surrendering to an infidel, rushed at him, and fired a pistol at his head. The ball, fortunately, only grazed his forehead. The Turk then leaped overboard, and endeavoured to swim on shore; but one of the English sailors, considering his conduct so unfair as to merit death, jumped into the sea after him, and, having overtaken him, deliberately cut his throat with a clasp-knife, as he had no other weapon, and then returned on board. The Greek Revolution too often gave occasions for displaying

"The instinct of the first-born Cain,
Which ever lurks somewhere in human hearts."

It was found impossible to get the two brigs afloat; and, as their sails had been landed, it would have been impossible to navigate them. They were therefore burnt; and another smaller vessel, which was so placed that Hastings would not expose his men by attempting to take possession of her, was destroyed by shells. A shell, exploding in her hull, blew her fore-mast into the water. For four hours the Karteria remained in the harbour of Volo. The corvette and brig had so completely silenced the fire of the batteries, that they appeared to be abandoned; while the guns of the castle only kept up an irregular and ill-directed fire on the Karteria. The magazines were all in flames from the effect of the red-hot shot fired into them; and, as night approached, the Karteria made the signal for all the vessels to make sail out of the harbour with a light breeze from the land. The spectacle offered by the bay as it grew dark was peculiarly grand. On the sombre outline of the hills round the gulf, innumerable fires were seen; and a continued discharge of musketry was heard proclaiming the arrival of each little band of troops which reached the camp at Volo. The lurid light thrown out by the flames from the burning magazines, and the reflection of the blazing transports, which were quickly consumed to the water's edge, enabled the steamer, in departing, to destroy the carriages of two guns which the Turks were endeavouring to get ready to salute the departing squadron.

Hastings had expected to find at Volo a large Turkish man-of-war, mounting sixteen heavy guns, and two mortars which had been constructed for the siege of Missolonghi, but which had not even got so far as Volo until after the fall of that place. This vessel was now waiting until the Turks should require her to bombard some seaport in the possession of the Greeks. A Greek fishing-boat came alongside to inform Hastings that the Pasha had ordered this vessel to Tricheri for greater security, where she was moored, with three schooners taken from the Greeks at Psara, in a small bay protected by a battery of twelve guns. In this position, she was considered perfectly safe from the attacks of the whole Greek fleet, aided by the fire-frigate herself, as the Turks called the Karteria. Hastings proceeded immediately to Tricheri, hoping to surprise the enemy by an attack during the night; but he found the Turks on the alert, and their well-directed fire of musketry rendered it impossible to continue the attack with the smallest chance of success.

At daylight next morning, Hastings examined the position of the enemy with care, but he saw there was no hope of capturing the bomb-ketch or any of the schooners; he therefore determined to confine his operations to destroying them. After getting up the steam and heating a few shot, he stood in to about three-quarters of a mile of the Turkish ship, and going slowly round in a large circle, he brought his long guns to bear successively, and fired them with the greatest deliberation. He then moved out of gun-shot of the Turkish battery to observe the effect of his fire. In about half an hour, a quantity of smoke was observed to issue from the large Turkish vessel, which the enemy appeared at first to disregard; but, in a short time, they seemed to discover that their ship was on fire, for they were seen hurrying down and rushing on board in great numbers. The carronades were now reloaded with shells, and the long guns with large grape, and the Karteria stood in to prevent the enemy from continuing his endeavours to extinguish the fire. The attention of the Turks was thus distracted; the flames soon burst through the decks of the ship, and, catching the rigging, rendered all approach to her impossible. In a short time she was a mass of flame; and her guns to the land-side, having been loaded, went off, discharging their shot into the battery formed for her protection. As her upper works burned away, she drifted from her station; but getting again on shore against the rocks, her magazine exploded, and the remains of her hull, with all her guns, sank in deep water. The three schooners also received several shells, and were so injured, as to be rendered unable to put to sea without undergoing great repairs.
