The island of Walcheren is thirty-four miles in circumference, including St. Jootsland, and is situated between the mouths of the East and West Scheldt, inclosed by Cadzand on the south, South Beveland and Wolfertsdyck on the east, and North Beveland on the north east. Our division of the fleet sailed from the Downs at half-past ten o'clock A. M. on the 30th, and came to anchor the next afternoon, in the East-Kapelle roads off Walcheren, when we observed the mortar and gun-vessels keeping up a heavy fire on the small town of Ter Veere, whilst a small body of English troops were lying behind the sand-hills, keeping watch on the road towards Middelburg, the capital of the island. Part of the fleet had already entered the Veere Gat, and had landed a large force, with three divisions of sailors (three hundred) the day before, at half-past four in the afternoon, on the Bree-sand, a little more than a mile west of Fort de Haak, the fire of which had been previously silenced by the gun-boats and mortars. The peaceable inhabitants sent a deputation from Middelburg to the head-quarters; the army advanced the next day, the 1st of August, and took possession of that place, drove the enemy into Flushing, and took from them some field-pieces. Gen. Sir John Hope landed his divisions in South Beveland the same day, and took possession of Ter Goes, the capital of the island, which is thirty-five miles long. The French fleet had retired beyond the chain which was drawn across the Scheldt near Fort Lillo. On the 3d, a few vessels were observed leaving Flushing; some boats were sent in chase; the weather was fine, the wind S.S.W., and the flood tide nearly down, which gave every hope of their effecting a safe return. The Raven sloop of war went to their protection, when the enemy's vessels again retreated into Flushing. The wind suddenly flew west in a squall, first blowing hard and then baffling. The boats got safe off, but the fire continued on the sloop for four hours without intermission, round shot passing through her from the Breskens batteries, and grape dropping on board from the ramparts of Flushing. She suffered severely in the hull, masts, and rigging, and had two guns dismounted, the top-mast shot away above the lower caps, the main-mast, bowsprit, and main-boom, rendered unserviceable, the sails and rigging completely cut in pieces, and her Commander, Capt. Hanchett, and eight men, wounded. Night coming on, she grounded on the Ellboog; at daybreak two brigs were sent to her assistance, and at seven she floated.
