FORE:Our forces in Sicily had an encounter, in the autumn, with those of Murat, King of Naples. Murat was ambitious of driving us out of Sicily, and Ferdinand IV. and his court with us. From spring till September he had an army lying at Scylla, Reggio, and in the hills overlooking the Strait of Messina, but he did not attempt to put across till the 18th of September. Seizing then the opportunity, when our flotilla of gunboats and our cruisers were off the station, he pushed across a body of three thousand five hundred men, under General Cavaignac. These troops were chiefly Neapolitans, but there were two battalions of Corsicans, and they were furnished with an embroidered standard to present to the Corsicans in our service, whom they hoped to induce to desert to them. General Cavaignac managed to land about seven miles to the south of Messina, and attacked the British right wing. Sir John Stuart made haste to bring up other troops to the support of the right, but before he could arrive, Colonel C. Campbell defeated the invaders, taking prisoners a colonel, a lieutenant-colonel, and forty other officers, with eight hundred men. There was a rapid retreat to their boats by the intruders, but the British pursued and cut to pieces great numbers of them, besides what were killed by the Sicilian peasantry. One boat full of soldiers was sunk as it went off, and the Neapolitans in another deserted to their old king.All this time "the great Admiral Vernon," as the Opposition delighted to call him, in disparagement of all the commanders favourable to the Government, lay still with his ships and afforded no assistance to the land troops. When Wentworth bitterly complained of this, to show that it was impossible to operate on the town from the harbour, Vernon sent into the inner harbour the Galicia, a Spanish ship which had been taken. This ship kept up a cannonade on the town for several hours, producing little effect, and was fired on from the town with as little. The men were then brought off in boats, the Galicia's cable was cut, and she was suffered to run upon a shoal, where she soon filled. The troops were now hastily re-embarked; the unhealthy season was at its height, and the men were swept away by fever more rapidly than they had been mowed down on land. The heavy rains had set in, and the troops in a few days were reduced to one half their number. Admiral Vernon instead of undertaking any enterprise which might have retrieved the honour of the British arms, set sail from Jamaica with the forces in July, and anchored in the south part of Cuba in a bay, on which he bestowed the appellation of Cumberland Harbour. Here the remains of that fine fleet and army, capable of achieving the most brilliant conquests under able commanders, were suffered to corrode away under the influence of inactivity, the season, bad salted provisions, and excess of rum.
